Possible causes of malfunction
The most common reason why an electric lighter and a record player stop working at the same time is a blown fuse. The fuse link in VAZs of these models is common for the circuits of the car player, rear window heater, interior heater and electric lighter. If a short circuit or malfunction occurs in each of these devices, the insert is destroyed and all listed circuits are switched off.
The reasons why the cigarette lighter and radio fuse fails are often as follows:
- destruction of the fuse element due to a short circuit or malfunction of devices connected through it;
- contact failure in the safety panel (due to shaking, mechanical impact, etc.);
- oxidation or burnout of contacts due to frequent power surges in the network;
- burnout of the cigarette lighter lamp;
- loose contact or burnt out spiral.
To determine the malfunction, you need to visually inspect and check with a tester the fuse-link and the devices whose circuits it disconnects.
Main nuances
So:
- Before connecting the car radio, you must carefully study the instructions, since incorrect actions will lead to equipment breakdown or even fire.
Connecting a VAZ 2109 car radio
- In modern players with automatic tuning, due to the wiring features of domestic cars designed for older models, settings may fail when turning the ignition key.
Note: therefore, it is also necessary to study the features of VAZ cars.
Troubleshooting the cigarette lighter and radio
Before starting repairs, you must find the fuse. Open the rectangular hatch to the left of the steering column of vehicles of the indicated models. Inside it there is a block of all fuse links of automotive electrical wiring. The element in the socket marked F4 is responsible for the operation of the cigarette lighter and radio on the VAZ-2114.
If the fuse looks normal externally, you can determine the open circuit in this place with a simple screwdriver tester. The light on the probe lights up when the element is working. Otherwise, you need to find a new 20 A insert in the repair kit, remove the faulty part from the socket and insert a new one. In most cases the problem is resolved.
If the safety element is working or has been replaced, but the cigarette lighter and radio do not work on the VAZ-2114, do the following:
- Check the radio's own fuse. It turns off only the player, so the inspection is carried out in the case when, after replacing the element in the block, only the cigarette lighter and electrical equipment for heating work (general: body and heating system), but the tape recorder is silent. The burnout of its safety element may indicate a breakdown in the music console, so it is recommended to have it checked in a workshop.
- Inspect and check the contacts of the fuse socket in the block. This is done if, after replacing the insert, the functionality of all devices is not restored. Tighten loose contacts and clean them from carbon deposits.
- Inspect the cigarette lighter and check it with a tester. The peculiarity of the backlight lamp is its serial connection into the electrical circuit. Its burnout causes a break in the circuit of the entire device, and additional electrical appliances connected to the socket (for example, charging a phone) do not work. A working cigarette lighter will work after replacing the lamp.
- Burnout of the heating coil is determined with a tester by applying its probes to the cigarette lighter contacts. In a faulty device, the resistance scale (Ohm) will display the value 0 (short circuit) or 1 (burnout). Indirect evidence of a malfunction is the additional devices connected to the socket: if the coil of the cigarette lighter itself burns out, then its socket remains operational and the phone will charge normally. The malfunction can only be eliminated by replacing the device. When purchasing a new one, it is advisable to immediately check its performance.
Sometimes devices stop working due to a break in the wires running from the fuse block to the cigarette lighter or radio. But in this case, only 1 device is always turned off, and the rest, connected through the same element, operate normally.
Trouble-shooting
Having established the reason why the VAZ cigarette lighter and radio are not working, we correct the detected breakdown. The list is given in accordance with the listed faults.
- We remove the fuse box (the hatch on the left side of the steering column of the car). We remove the device marked F4 (20 ampere fuse), test it for serviceability with a simple screwdriver probe, if this moment is not visually determined. And we replace it with a new one from the mandatory kit for such cases.
- Check the conductivity of the contacts with a probe. If they are loose, tighten them.
- Strip or resolder the contacts, depending on the situation.
Paradoxically, a burnt-out light bulb breaks the contact circuit (a kind of fuse). Replace it with a working one of the same power.
A short circuit most often occurs due to a loose cigarette lighter socket and a malfunction of its heating coil. If you have the opportunity, then replace them with new ones or restore them to proper condition.
Expert advice
Professional automotive electrical repair technicians complain that even when carrying out repairs that are so insignificant in scope and complexity on their own. Some car owners manage to violate basic rules, thereby significantly aggravating the problem and transferring it to another, more complex (and expensive) repair category.
It is for this reason that we provide several recommendations for replacing and repairing car cigarette lighters.
No replacing fuses with improvised means (despite the advice of so-called experienced drivers). A single case of such a replacement cannot serve as a reason for its re-use.
A definite no to any direct connections (twists). All work must be done using a soldering iron.
When purchasing a new cigarette lighter from an unknown retail outlet, if possible, check its serviceability and quality, using a tester and visually.
Before working on any electrical appliance, be sure to de-energize the vehicle's electrical system. Otherwise, in addition to shorting, you expose yourself to the risk of electric shock.
Do not neglect to carefully study the instructions and any available information.
Don't be overly confident. If you doubt your capabilities, seek help from professionals.
Do not think that this problem is typical only for VAZ 2114 (2115, 2109, 2110, 21099) cars. The same malfunctions with some (minor) differences are often found in imported passenger cars. As an example, we can cite the Daewoo Matiz, Renault Logan, Toyota Corolla and a number of other models of various brands.
Additional Tips
The cigarette lighter socket in the VAZ-2115, as well as 14, 09 and other models is designed to power the following household appliances:
- phone charger;
- tablet or laptop;
- pump for car wheels;
- car vacuum cleaner and other household appliances with a special connector and the ability to be powered from a 12 V network.
When such devices are turned on for a long period of time or when moving, the contacts overheat and burn. Frequent use of the cigarette lighter socket leads to its rapid failure and can cause the fuse common with the radio to blow out.
If, after replacing fuse element F4, the functionality of the radio is not restored, the cause may be a blown starter fuse.
Replacing this insert (No. 14) sometimes quickly solves the problem. To prevent the starter safety insert from burning out, when performing work using the cigarette lighter while parked (for example, inflating a tire, cleaning the interior) or listening to the radio, you need to start the car to idle.
You cannot replace blown fuses with bugs. Homemade inserts are unable to melt in time in the event of a malfunction in the electrical circuit or devices. This may cause the wiring to catch fire.
When repairing contacts, it is not recommended to twist the wires. This method causes local heating of the contact and can also lead to a fire. In automotive circuits, you need to solder all contacts well or use special fastening connectors.
Additional recommendations
First of all, you need to avoid the temptation to solve the problem quickly by replacing the faulty fuse with something that comes to hand that can close the necessary contacts in the block.
For the same reason - in order not to provoke a more serious breakdown (fire, short circuit or melting) - you cannot get by with simply twisting the wires: you should definitely use a soldering iron with solder.
You should be careful when buying a new fuse or, especially, a cigarette lighter - low-quality counterfeits or uncertified products can fail immediately, so they should be checked in the store with a tester under load.
Finally, before starting work on repairing electrical appliances, it is strictly recommended to turn off the power to the car by removing the terminals from the battery. If you are unsure of your abilities, it is better to contact a professional car service center, or at least carefully study the relevant instructions (you can find them for any VAZ model, including 2114, on the Internet).
Why the cigarette lighter and radio do not work on the VAZ-2114
VAZ cars, including the 2114 model, are distinguished by ease of maintenance and reliability. However, even these sometimes break down. For example, the following may occur: the radio tape recorder fails and at the same time the cigarette lighter stops working. These two troubles confuse many, but in fact, the simultaneous failure of the mentioned nodes is a very characteristic sign that greatly facilitates the search for the cause. How to find out why the cigarette lighter along with the radio stopped working, and what to do in this situation - we will tell you further.
What does the radio have to do with it?
There are situations when the radio and cigarette lighter of the VAZ-2114
simultaneously. You say: what connection could there be here? That's right, it shouldn't exist. But some “electricians” or car owners themselves connect the power of the radio to the cigarette lighter contacts. This is much easier than running wires to the battery terminals. So it turns out that when the cigarette lighter fuse blows, the radio stops working. In this case, it is better to contact a qualified auto electrician to correct the situation.
Car cigarette lighter - features
A few decades ago, the unit in question performed only its main and then only function - it allowed you to light a cigarette. Much has changed since those times, and now its socket is used more often as a universal socket that allows power from the on-board network:
- smartphones;
- navigators;
- tablet computers;
- video recorders;
- vacuum cleaners;
- compressors, etc.
Thus, the functionality of the cigarette lighter (or rather, its socket) has increased significantly. The problems of the element in question arise from the low reliability of the connection and the transmission of excessively high power current. The cigarette lighter socket is not very suitable for powering household appliances and is not able to provide proper contact.
Vibrations, the weight of adapters and careless movements - both by the driver and passengers - often lead to the connection being broken and sparking occurring. The socket clamps are also gradually loosened. All this can lead to a short circuit, damaging both the electrical circuit of the VAZ itself and its individual elements.
Functions and design of the VAZ-2114 cigarette lighter
Drivers often use a device such as a cigarette lighter for other than its intended purpose - as a 12 V car socket. How is this possible? To understand this, you need to know the design of the cigarette lighter. Its constituent elements are:
- the socket, which serves to connect to the ground of the vehicle, is equipped with a central terminal for connection to the “+” conductive on-board circuit;
- insert with nichrome spiral.
Both the socket and the insert are enclosed in a metal case, on which there is a power button that acts as a handle. When you press the handle button, the current begins to move along the nichrome spiral, heating it. You can light a cigarette this way.
But if you remove the insert with the nichrome spiral from the glass socket, the cigarette lighter will become a twelve-volt socket. You will need a suitable cylinder-shaped plug for this. It is not difficult to find: modern electrical appliances for cars are equipped with similar plugs for ease of use. It is from connecting various electronic devices, such as a car vacuum cleaner or a compressor for inflating tires, to the cigarette lighter socket that the fuse of this device can fail.
Why does the radio fail?
On the VAZ-2114, the mentioned reproducing device is connected to the same circuit as the cigarette lighter. Thus, if its common elements are damaged, then both devices will not work.
This, by the way, is not all - in addition to the cigarette lighter and radio itself, other quite important devices are connected to the same circuit:
- cabin stove;
- heated rear window;
- backlight
For this reason, having identified a failure of the first two devices, we advise you to immediately check whether the others are working.
In most cases, failure of the VAZ-2114 cigarette lighter (and along with it the radio) occurs due to a blown fuse. After all, since they have one electrical circuit, it is protected by a common device. The problem is that its fuse link is not always able to withstand the load arising from the parallel operation of several consumers - accordingly, it simply burns out. Short circuits occurring in any of the loops can lead to a similar result. These are not all the reasons causing problems.
So, in particular, circuit failure is sometimes caused by:
- oxidation of contact groups in connecting terminals or safety block;
- break of one or more common wires;
- burnout of the backlight lamp.
To find the root cause of the problem, you must check all the above options and fix the problem found.
In general, the work is not very complicated, and the knowledge gained in physics lessons in high school is enough to complete it. If you are not confident in your abilities, we recommend asking for help from a more experienced car enthusiast or going to a service station. In this case, you are guaranteed to avoid mistakes, which often lead to more serious problems and, consequently, unnecessary costs.
Next, we will consider each reason and how to eliminate it in more detail.
Why does a fuse blow?
Having determined that the cigarette lighter on a VAZ-2114 does not work due to a blown fuse, it is worth thinking about the cause of this malfunction, because with normal operation of the on-board network, the fuse link can last for years. Its failure can be caused by a short circuit in the motor circuits of the interior heater, windshield washer, glove compartment light, or rear window heating relay. The fact is that the safety of all these circuits is ensured by the same fuse that ensures the safe operation of the cigarette lighter.
Another reason for the fuse link to burn out may be the inattention or negligence of the car owner himself when operating additional electrical appliances. If you recently vacuumed the interior of your car or inflated the tires with a compressor, connecting the equipment to a “car socket,” and then the VAZ-2114 cigarette lighter stopped working, you can be sure that it was these devices that contributed to the failure of the fuse.
Why does the cigarette lighter on the VAZ 2110 not work?
When using such devices, it is necessary to take into account the amount of current consumed and not allow it to be greater than that of the machine’s on-board network.
Fuse
As noted above, the first thing you should look at if the cigarette lighter or the same radio fails is the fuse. This device is designed to protect not only devices connected to the on-board power supply, but also the electrical network itself.
The required element is located in a block located in the car interior to the left of the steering wheel, and is designated as F4. Its standard rating is 20 amperes, but even this safety margin is not always enough if the car owner regularly overloads the system with too voracious consumers.
The fuse should be held up to the light. If there are no signs of burn-through, then it must be checked with a tester (installed on ohms).
When a break in the fuse link is detected, the element is replaced with a functional one, and in the absence of one, it is permissible to install a temporary external jumper. Its cross-section is 0.51 square. To make a “bug”, 5-6 veins taken from any power wire are suitable.
After replacing the fuse, you need to check whether the cigarette lighter and stereo system work. If they still show no signs of life, then you will have to look further.
Where to look for a blown fuse
Has the cigarette lighter on your VAZ-2114 stopped working and there is no voltage at its contacts? Start your diagnosis by checking the fuse. To do this, you don’t have to disassemble anything, and the only tools you need are a multimeter in tester mode or a homemade tester made from a lamp and two wires.
A natural question that arises in a situation when the VAZ-2114 cigarette lighter does not work: “Which fuse should be checked and where to look for it? “
In the Samara model fourteen, this protection element is located in the mounting block located in the engine compartment of the car. Open the hood and in the far right corner (looking at the windshield) you will see a black plastic box. This is the car's mounting block.
The cigarette lighter fuse, depending on the modification of the car, may be designated as F4 or F7. It is designed for a maximum current of 30 A (in some modifications its rating can be 20 A).
Contacts
Any detachable connection by default is a weak point in the electrical circuit.
Therefore, immediately after the fuses, you should check the condition of the contacts, because their malfunction can also be the reason why the devices discussed in the article do not work in your VAZ. In domestic cars, the terminals of the fuse socket or connecting blocks often fail. If they are poorly connected or contaminated, the contact resistance increases and, accordingly, the metal elements heat up. This effect provokes the melting of the plastic, which, in turn, flows between the contacts and creates an insulating layer.
To find such a malfunction, it is enough to inspect the pads, starting with the safety ones and ending with those that go to the devices. It is very difficult not to notice traces of burning. Similarly, oxidation and simply poor contact contacts worsen conductivity. In the first case, the metal elements of the terminals must be cleaned with a regular school rubber band, and in the second case, the clamps must be adjusted.
What can happen to the cigarette lighter
If the cigarette lighter in your VAZ-2114 does not work, you will prefer only two circumstances: either the integrity of the nichrome spiral is broken, or there is no voltage on the contacts of the glass. An ordinary auto tester, in other words, a multimeter turned on and working in voltmeter mode, will help you find the problem.
Attach one probe of the device to the positive terminal of the glass, and bring the second one to its body. The voltmeter should show battery voltage. Here you can simply change the insert with the spiral, and the cigarette lighter works like new again. If there is no voltage on the contacts, you need to continue to find the problem.
KEY-DOP
Wires
Broken wiring is a very common problem in domestic cars. Often it is impossible to determine by eye where exactly the malfunction has occurred, and therefore a multimeter should be used.
Testing starts from the fuse if the radio or cigarette lighter fails at the same time, and from one of the devices when it is the only one that does not work.
Once a faulty core is discovered, it must be replaced immediately - we do not recommend twisting it or wrapping it with electrical tape. As noted above, any connection becomes a weak point in the chain.
Which fuse controls the radio?
As protection of electrical circuits for all cars, incl. on the VAZ-2110 and VAZ-2112, low-fusible fuses are installed, which blow out, protecting the electrical network from a short circuit. Depending on the load of electrical circuits, they are distinguished by the rated current strength, the value of which is indicated on them. Not only the safety jumpers are marked, but also the connector sockets in which these low-melting membranes are located.
The VAZ radio fuse with a current of 20 A and marked F4 is located in the compartment on the right side of the steering mechanism. This element is responsible not only for the car radio, but also for the right fog lamp.
Sometimes on the same vehicle models, but of different years of manufacture, the markings of devices responsible for the electrical circuit are different. Thus, a car radio is often connected to the power system via fuses F10 or F4, where F10 is a backup connector used in the event of any breakdown.
How to use a cigarette lighter so that it works for a long time
If you use your cigarette lighter correctly, you will maintain its usability for a long time.
First of all, you should not connect to it powerful consumers such as a compressor, which many now use to inflate wheels or blow air into the power unit. It is more correct to power this device through a rechargeable battery.
In this way, you will protect the wiring and fuses from overloads, and, therefore, they will not overheat, burn out or melt. Some craftsmen install a separate socket in the car for such devices - this is very forward-thinking and effective.
Also try not to stick adapters into the VAZ socket if it turns out that they are too thick - this will quickly break the core, which is made of ceramic.
Design and purpose of the cigarette lighter
Some car models simply do not have a cigarette lighter. Drivers of these cars light cigarettes from ordinary lighters, and to connect electronic gadgets in such cars a 12-volt socket is used. But in domestically produced machines, AP is an integral structural element.
New AP for VAZ 2114
If we talk directly about the device, then the AP is a power outlet; a separate circuit with a safety element is allocated for it. The VAZ 2114 cigarette lighter itself consists of a special nichrome spiral. This element heats up when voltage is applied to it, so much so that touching it can cause a burn.
A thermal relay is located in the design socket. The purpose of this component is to turn off the coil when its temperature reaches its maximum. The thermal relay opens the contacts of the device, after which the ejection mechanism comes into operation.
Why the cigarette lighter and radio do not work on the VAZ-2114
Some components that belong to the electrical system are interconnected, so drivers often have complaints that the cigarette lighter and radio in the VAZ-2114 car do not work at the same time ✔. Often the cause of a malfunction is the connection of devices whose power exceeds the permitted value.
What is the Samara cigarette lighter of the fourteenth model
The design of the cigarette lighter for the VAZ-2114 is the same as for other cars. It consists of a glass (socket) and an insert. The socket is an iron cylinder, the walls of which are connected to the “ground” of the car. It is also equipped with a central terminal connected to the “plus” of the on-board circuit.
The main element of the insert is a nichrome spiral. It is enclosed in an iron case with a plastic button-handle. The insert is located inside the glass. In the off position, its body is in contact only with ground. When you press the button, the insert goes deeper into the glass, where one of the spiral contacts comes into contact with its central terminal, completing the circuit. It is held in the socket thanks to two special bimetallic “ears”. The current passing inside the spiral heats it red hot. For this reason, we can actually light a cigarette.
Why does the cigarette lighter on the VAZ 2114 not work?
The device turns off automatically. When the glass is heated to a certain temperature, the “ears” unclench and release the insert. In this case, a corresponding click is heard, notifying the driver that the device has turned off and is ready for use.
Basic fuse faults
Fuses in cars play an essential role, protecting electrical appliances from power surges and short circuits. They take on the impact of such factors and maintain the working condition of the electrical appliance, while burning out themselves. But if this happens regularly, you need to check the fuse box and determine the cause of the breakdown.
Bad contacts
One of the most common reasons for a situation where a fuse does not work is related to the contact group. With frequent voltage surges in most VAZ cars, contacts burn out and plastic melts, which can interrupt the contact of parts. A similar condition is also observed when the contacts have oxidized and become coated.
Broken wiring
When operating a car, malfunctions such as broken wires often occur. To determine for yourself where the accident occurred, you will need a special device (multimeter, tester) with which to check the working condition of the contacts. To find an open circuit, the device is set to ohmmeter mode, and the leads are connected to the circuit being tested. In the place where the wiring is broken, there is high resistance.
Are you a car driver?! Then you can take this simple test and find out. Go to test »
Short circuit
A short circuit occurs when the contacts in the block are strongly oxidized and crossed due to frequent use of the cigarette lighter socket. This condition is indicated by a fuse blowing shortly after replacing it. To determine the short circuit zone, you need:
- Inspect the entire area for damage.
- Disconnect the section being tested from the main wiring.
- Use a multimeter to set the dialing mode.
If there is a short circuit in the area being tested, the device beeps.
Bulb burnout
The contacts of the light bulb are in a common electrical circuit, so when it burns out, the cigarette lighter and radio on the VAZ also stop working. The reason for their burnout may be high voltage, breaks or short circuits in the wiring, water or poor fastening.
VOLTAGE REGULATOR
It is not difficult to find where the VAZ 2114 generator relay is located. This device is located at the back of the generator itself under a plastic cover. Where is the charging relay located on the VAZ 2114 - a question for backfilling. The fact is that the charging relay, generator relay and voltage regulator on the VAZ 14th are generally one and the same single device. It is also called a relay regulator.
What happens if the voltage in an electrical circuit drops below 13.2 Volts? The battery will stop charging, and after a fairly short period of time the starter will no longer have enough power to crank the engine to start. What if it is over 14.7 Volts? Then elements of the electrical circuit may fail, for example, the radio or one of the engine sensors (mass air flow sensor, phase sensor, etc.) will burn out.
The charging relay on the VAZ 2114 looks like a large black tablet, at the end of which there are two graphite brushes (brush assembly). If there is little or no charging, the voltage regulator is checked.
Voltage regulator location
DIAGNOSTICS OF RELAY REGULATOR
Checking the functionality of the generator on a VAZ 2114 always begins by measuring the voltage of the on-board circuit with the engine running. The most convenient way to measure is with a digital multimeter:
- We set up the multimeter to measure voltage and set the upper limit to 20 Volts;
- We connect the probes of the device to the battery and measure the voltage with the engine turned off. The voltmeter should show somewhere between 12.5 and 13 volts;
- We start the engine, the readings of the device with a good working generator should increase to about 14 Volts (maybe a little more);
- With the engine running, turn on the load (high beam, dimensions, heated rear window, heater motor at maximum speed). We look at the readings of the multimeter - the device should not show less than 13.2 Volts at idle, but it is better if this indicator is in the range of 13.8-13.9.
Checking the generator voltage regulator can also be carried out on a removed device. The device assembled with the brush assembly is checked. For this:
- We connect the mass terminal (minus) of the “tablet” with a wire to the minus of the battery.
- We supply power (12-14 Volts) to terminals “B” and “C” from the battery.
- We connect a 1-3 Watt car lamp to graphite brushes. If the relay-regulator is working properly, the lamp should light up.
There is another way to check the operation of the voltage regulator - when you need to check what the regulator's response threshold is at the upper limit. To do this, we increase the voltage in the circuit, for example, in parallel we add two or three 1.5 V AA batteries to the circuit. We need to increase the voltage to more than 16 volts, we connect everything else according to the same circuit. In this case, if the charging relay is working properly, the lamp should no longer light up.
Summarizing the results of both checks, we draw the following conclusions:
- If the lamp lights up during the first check, but does not light up during the second, then the voltage regulator is working;
- If the lamp lights up during both tests, the regulator has a breakdown;
- If it does not light up in either case, there is a break in the device between the brushes or contacts.
REPLACEMENT
We proceed as follows:
- Disconnect the battery terminals;
- We unscrew the nut by 10 with a wrench and move aside the positive wires going to the generator (red and black);
- We pull off the chip with a thin wire;
- Remove the rear plastic cover of the generator. It is attached to three clamps, and to remove it, the clamps must be bent;
- The relay regulator is mounted on two screws. Take a Phillips screwdriver and unscrew the screws;
- The “tablet” remains hanging on the wire. Carefully pull out the plug from the device and dismantle the regulator;
- We install the new part in the reverse order.
You can replace the relay regulator by removing the generator; here everyone chooses the method that will be most convenient.
Repair
Finding the reason why the cigarette lighter and radio failed on a VAZ-2114 is not so difficult. Often the problem is hidden in the contact group or in the fuse box.
To eliminate breakdowns associated with poor contacts, you should start by checking all the contact blocks of the wires that go from the fuse box to the cigarette lighter and radio. Insufficient contact and its oxidation lead to breakdown of elements.
Broken wiring cannot be repaired, it can only be replaced with a new one. Some motorists try to solve the problem using the old and proven method, connecting the damaged area with insulating tape. However, experts do not recommend repairing the wiring in such a way that new faults in the form of a short circuit do not appear in the future.
You can solve the short circuit problem by replacing the socket with a better one.
The use of cheap products leads to breakdowns after a short period of time.
To repair the interior lighting, you need to replace the burnt-out element. If the situation repeats frequently, it is recommended to eliminate the cause: buy suitable light bulbs taking into account the voltage, check the wiring and the socket for attaching the light bulbs.
Why it breaks and what to do
Experts say that there are only 2 reasons leading to cigarette lighter failure:
- fuse blown;
- loss of any contact.
In the first case, you will need to replace the melted protective device with a working one. It is located directly in the mounting block. So, if you have:
- low instrument panel (that is, an older car), then this is F4 or F10;
- high panel – 11.
It is worth noting that in this situation the following will also stop working:
- rear window heating element;
- socket for extension cord.
In early cars the fuse rating was 20 amperes, in new ones it was only 16.
By the way, the stove is powered through F7 in old models, 4 in new ones.
The blown fuse is removed with the battery disconnected and replaced with a new one. It is important to monitor his condition for some time. If it burns out again, then you should look for the cause in a short circuit.
If contact is lost, you must:
- inspect the cigarette lighter socket;
- make sure that all wires are holding well;
- use a tester to check the voltage (black and red wires - should be 12 volts).
If everything is in order, then you should look for the problem in the socket. If there is no electricity, inspect the wiring for integrity.
It is important to understand that the cigarette lighter itself has a certain margin of safety, and not every load will pass without leaving a mark on it. If the norm is exceeded, the risk of breakdown increases. Therefore, you need to be more attentive to the selection of gadgets, giving preference to the most energy-saving ones.
Design features of the fuse box on the VAZ-2114
Structurally, it turned out that along the contact line the radio and cigarette lighter lie in the same branch, and therefore, as practice shows, if one does not work, then the second should not work either.
And since this is AvtoVAZ, there is nothing surprising here and the problem can arise quite often.
The connection between the radio and the cigarette lighter in the design is direct. So, several electrical devices are connected to one branch of the electrical circuit at once and, in addition to those already mentioned, the rear window heating and the interior heater can be connected.
Why don't the radio and cigarette lighter work?
Removed mounting block from the car.
Since the radio and cigarette lighter are electrical devices and are fed into one branch of the on-board network, then, most likely, faults must be looked for in the electrical part.
The main cause of the malfunction is the fuse , which cannot withstand the load that the user puts on it. Thus, connecting additional devices may cause a short circuit, which will cause the fuse to burn. But, as practice shows, these are not all problems that will be associated with a non-working radio and cigarette lighter.
So, let's consider what other reasons may arise due to operation:
- Connecting contacts to the safety group.
- Oxidation of contacts.
- Broken wire.
- Short circuit.
- Backlight bulb burnout.
VAZ 2114 cigarette lighter fuse: location, breakdowns and their elimination
Sometimes motorists are faced with the fact that the cigarette lighter on a VAZ 2114 does not work. This seemingly minor problem can lead to very big difficulties on the road. Indeed, nowadays a car cigarette lighter not only serves its intended purpose, but is also used to connect various chargers (for example, for smartphones) and to power some electronic devices directly (for example, navigators).
That is why it is so important to understand the electronic circuit of the cigarette lighter and be able to repair it in a timely manner. We'll talk about how to do this today.
Methods for solving the problem
Now that the main causes have been sorted out, you can move directly to elimination methods.
It is worth warning that if the motorist does not understand the design or is not sure that he can repair the fault on his own, then it is recommended to turn to a professional car service center.
So, let's look at what ways to deal with the malfunction.
Fuse
Disassembled dashboard while searching for fuse and cigarette lighter faults.
The most common cause of malfunction or inoperability of the electrical circuit of individual elements is the notorious fuse.
This is where you need to look for the cause first.
The fuse box socket – F4 – is responsible for the radio and cigarette lighter. The fuse marking in it should be 20A.
But it does not always withstand the load placed on it. Thus, frequent and large use of additional devices can lead to frequent burnout of this element. Therefore, to check it is worth removing and inspecting the fuse itself. If necessary, the element is replaced with new ones and if everything works, then the reason has been found. But if the problem does not go away, then you should look for it in other places.
Contacts
Checking the contact group of fuses for malfunction
A contact group is another common cause of a non-functioning electrical circuit. In most VAZs, the connecting contacts of the fuse with the block or in the circuit of the wire block oxidize or burn out, and molten plastic can interrupt the contacts.
To troubleshoot the problem, you need to check all the contact blocks of the wires that go from the radio and cigarette lighter to the fuse box. So, it is oxidation and insufficient contact that can lead to the inoperability of the elements.
Wiring
Another reason could be broken power wires. So, in order to find and fix the fault, you will need a tester that will test the wiring and find a broken wire . It is recommended not to fasten the wire using the old “old-fashioned method” using electrical tape, but to replace it with a new one. This will take little time, so it’s better to do everything in such a way that you get a short circuit and cause big problems.
Short circuit
Location of frequent failure of the cigarette lighter socket.
The worst thing that can happen is a short circuit. The reason for this phenomenon is that frequent use of the cigarette lighter loosens the socket and this can lead to the contacts crossing and causing a short circuit.
The standard cigarette lighter is just a disaster for the VAZ-2114.
Here, the treatment for the malfunction is quite simple - replacing the socket. But, often motorists take a low-quality and cheap product, which repeats the procedure after a short time.
Bulb
Cigarette lighter illumination at night VAZ-2114.
The backlight bulb is located in the same electrical circuit, so the burnout of this element causes a malfunction of the radio and the cigarette lighter at the same time. So, if you replace the element, you can correct the situation.
Fuse and relay box
The fuse and relay box is located on the left, lower part of the instrument panel. It is accessible by pressing the button and folding the lid down. To remove fuses, there are special non-conductive pliers in the upper left part of the mounting block.
1 - K5 - high beam relay. If the high beams in two headlights do not work, check this relay. If one of the high beam headlights does not work, check fuses F3 and F13, as well as the lamps and the high beam switch.
2 - K4 - low beam relay. If the low beam in both headlights does not work, check this relay. If only one low beam headlight does not work, check fuses F2 and F12, as well as the lamps themselves and the light switch.
3 - K1 - lamp health control relay.
4 - non-conductive tweezers for removing fuses.
5 - power window relay. If your power windows stop working, check this relay. It could also be in fuse F5, or in the window lift drive system itself. To get to the mechanism, you need to remove the door trim. Check the electric motor, the appearance of the gears and the absence of binding of the mechanism.
6 - K3 - turn signal and hazard warning relay. If your turn signals or hazard lights do not work, check this relay and fuse F16, as well as the turn signal lamps themselves and their switch.
7 - starter relay. If the car does not start and the starter does not turn, check this relay. It could also be a dead battery, as well as the starter mechanism itself.
8 - backup fuses.
9 - fog lamp relay. If the fog lights do not work, check this relay and fuses F4 and F14. Also check their connection diagram, the serviceability of the wiring and connectors, as well as the lamps in the headlights and the power button.
10 - K2 - windshield wiper and washer relay. If your windshield wipers or windshield washer are not working, check this relay. Also check the wiper motor, washer pump and washer fluid level in the washer reservoir.
11 - K7 - rear window heating relay. If the heating does not work and the rear window fogs up, check this relay and fuses F8 and F9. Also check the connection contacts to the terminal points of the heating elements (at the edges of the glass at the rear pillars). If everything is in order, but the heating does not work, the issue may be in the wiring (the wires are frayed or something else).
12 - K6 - add. relay, ignition relay. If your ignition does not turn on or is having problems with it, check this relay. This relay protects the ignition switch contacts from burning. Also check the ignition switch itself and the contact group.
