Dear car owners! The other day I encountered, at first glance, a simple, but for me not obvious problem: the lights on a VAZ 2114 do not light up. The problem bothers me regularly, a year ago the lights and feet stopped lighting up, I cleaned the contacts and ground, it seemed to help for a while. Then it worsens again! Today only the turn lights are on, that's all. Where could the cause of this unpleasant problem for me be hidden?
Hello! I myself recently dealt with side lights, I had to do a lot of work, but in the end I solved my problem. I'll help you too. First check the lamps, perhaps they are simply burnt out, which is why the side lights do not work (corny, but it happens so often!). Another possibility: the fuse has blown. It needs to be replaced if this is exactly what happened. You need to climb into the mounting block and find F10 there. When it burns out, both side lights do not light up, as well as the license plate lights.
Nothing complicated, I hope you can figure it out. Go ahead. We check the contacts. They could have oxidized, which is why the dimensions do not work. We carry out a visual inspection of all the pads, take them out and put them back in. This is exactly how I solved my problem. I cleaned the contacts and everything was fine. If cleaning does not help, then we check the button itself. It may not work, unscrew it and look. Has the wire fallen off? So it doesn't work!
The most serious reason is a short circuit. But even here you can cope on your own. We take a regular light bulb and connect two wires to it: plus and minus. Next, we take out the fuse and connect the wires from the lamp in place of its contacts. If it starts to burn, it means there is definitely a short circuit somewhere. The only way to find the short circuit is to turn off everything connected to the fuse in order.
Where does it short out most often?
I will try to make your task a little easier in finding the location of the short circuit, if, of course, this is appropriate in your case. But, if all the methods described above did not bring a positive result, then this is the only option left. The wires that go to the license plate lights, as well as to the trunk roof, most often fray and short out there. This wiring needs to be treated with electrical tape, and nothing else.
Another problem area is the wiring on the back of the fender under the carpet. There, too, you need to look at everything carefully, and, if necessary, wrap it with electrical tape. Yes, there are cases when both light bulbs burn out, but drivers refuse to believe it, checking everything but the lights themselves. Start with them. That's all, good luck!
Tips for motorists
When driving a VAZ-2115 passenger car, regardless of the time of day, the side lights, as well as the headlights, must be turned on. This is a requirement of the Russian Traffic Rules that every driver must comply with. Therefore, the electrical circuits of side lights and brake lights operate through the K4 lamp control relay, the task of which is to warn the driver with a light and sound signal that at least one of the lamps of the above listed electrical circuits is not turned on. This will force the driver to get out of the car and determine which side light lamp is not on and begin to search for the problem.
On a VAZ-2115 car, the side light lamps in the rear lights often stop working. This is due to the occurrence of leaks in the lamps, as a result of which moisture gets inside, which leads to oxidation of the plug of the block or the track on the flexible circuit board, through which voltage is supplied to the lamp contacts.
There are cases when, after moving the exterior lighting switch to the first position, not a single side light lamp lights up. The search for such a malfunction will have to begin by checking the presence of voltage at terminal 1 of this switch. It should be +12 volts, even with the ignition off.
If this terminal is de-energized, then you will need to sequentially check the voltage at terminal 6 of connector X8, and then at terminal 6 of connector X1 of the mounting block. If there is voltage at these terminals, the culprit for the lack of power at terminal 1 of the outdoor lighting switch will be the pink wire connecting it to terminal 6 of connector X1 of the mounting block.
Well, if there is voltage at terminal 1 of the external lighting switch, the culprit for the side lamps not turning on may be the switch itself or the K4 lamp control relay. To make sure that the switch is out of order, you need to move it to the first on position and check for voltage at its terminal 2. If there is no voltage at this terminal, then the outdoor lighting switch will have to be replaced.
If fuse F10 (7.5 A) blows, the front and rear side lamps on the left side of the VAZ-2115 car will not light up, and if fuse F11 (7.5 A) fails, both side light bulbs on the right side of this vehicle will not light up. car. The blown fuse F10 can be determined instantly, without even looking into the mounting block, since the backlight lamps for switches, heater control levers, cigarette lighter, and ashtray immediately turn off, because it also protects these electrical circuits.

When driving at night or in fog, side lights are indispensable, especially if they are located at the rear. When moving or while parked, they show other motorists where your vehicle is. If the rear lights on a VAZ-2114 car do not light up, then it will not be difficult to do the repair yourself. To do this, just find out the reason and follow the instructions below, or watch the video.
Features of the operation of dimensions on the VAZ 2114
Being the ideological heir of the first generation, the “fourteenth” inherited from it many technological solutions, including external lighting devices. Thus, the dimensions on the VAZ 2114 are located in the corner areas of the body at the front and rear, which, according to technical regulations, are included in the general blocks of lamps and headlights.
At the same time, there are several features that should be noted when describing the side lights on the VAZ 2114:
- on/off is carried out by a button in the exterior light control module;
- when the lights are on, the switch is illuminated by a green indicator diode;
- The rear lights of the VAZ 2114, unlike the front ones, light up in red, in accordance with Russian road safety standards.
A dedicated fuse block is responsible for the correct operation of the side lamps on this Lada, which can be found in the engine compartment next to the engine. Accordingly, most often motorists who notice non-functioning dimensions on the left or right side of the car are faced with a failed fuse.
The easiest way to diagnose the failure of fuse F10, since it simultaneously acts as a warning lamp, whereas if a pair of dimensions on the left side of the car is not working, fuse F11 will most likely have to be replaced.
Features of this tuning
The brake light in the spoiler has a number of advantages:
- It's stylish, that's why they buy spoilers. Without a spoiler, the VAZ looks like a simple classic car, even a kind of retro, but with a spoiler it looks quite original.
- The spoiler best conveys the stop signal, and you can come up with any animation that attracts attention, but you need to be careful with this.
- The spoiler has a low price, and almost every driver can install it independently.
- The spoiler is installed once for many years, so it is beautiful and profitable.
- The brake light on the spoiler is more visible, so even from a road safety standpoint, the spoiler wins.
Although the spoiler is a decoration of the car, it is difficult to say why it is installed on the VAZ. Most likely, this is due to the fact that the car of the classic brand looks modernized and stylish compared to the standard version.
Causes of malfunctioning rear lights
Troubleshooting a situation with non-working side lights is the primary task of the car owner, as this not only creates a dangerous situation on the road, but also, in the end, is fraught with a fine from the traffic police.
To find out why the dimensions of the VAZ 2114 do not light up, you need to focus on three main factors:
- Burnt out lamp.
- Loose contact of the power wire.
- Broken wiring leading to the gauge.
The first case is the most common, and the problem is solved by simply replacing the light bulb, fortunately, they are sold everywhere and cost little money.
You can confirm the second reason without disassembling the device by simply tapping on the size: the moment you press it to the contact, the lamp will light up, and vice versa, it will go out in the free position. If disassembling the device did not reveal any oxidation with carbon deposits, a burnt-out lamp or a loose terminal, but the rear marker of the VAZ 2114 still does not light up, we can talk about faulty wiring.
What is especially important to control at the rear dimensions
If the control light on the key does not light up, but the dimensions work, then first look at the panel wiring. Remove the key block from the socket, then wipe the contacts with alcohol. If the dimensions on the right side do not work simultaneously with the warning lamp, then check the fuse. It is worth noting that they rarely fail, since the VAZ-2114 began to install wide options that have a reliable contact pad.
If F10 or F11 still breaks down frequently, then it is necessary to check the mounting block; it may be faulty. If this unit is in working order, then check the entire electrical circuit. Sometimes constant failure of fuses indicates a short circuit in the wiring, which can lead to a car fire for no apparent reason.

Side lights are lamps that let another car know about your dimensions. For example, stopping at the side of the road on the highway and turning off the ignition, the low beam goes out, but the dimensions remain. And according to traffic rules, for your information, parking on the side of the road is allowed only with the lights turned on.
In this article we will look at the main reasons why the lights on the VAZ 2114 do not light up. This article is suitable for all samar owners, both the first generation and the latest.
Replacing a broken light bulb
To repair the rear lights of a VAZ 2114, you need to follow a number of simple recommendations:
- turn off the vehicle's power supply;
- open the trunk, remove the decorative trim;
- Squeeze the latches and remove the contact panel of the entire flashlight;
- press down the faulty lamp and turn it counterclockwise to remove it.
Next, it is advisable to “ring” the lamp with a tester to make sure that it was its malfunction that was the cause of the problem, after which it should be replaced with a new analogue, and you can begin assembling the lamp in the reverse order.
Some Lada owners, faced with the fact that the dimensions on their VAZ 2114 do not work, do not bother and change the entire headlamp assembly - especially since they are not so expensive. This can be considered a convenient solution, since such a replacement eliminates for some time the possibility of failure of other lamps in the flashlight, in addition to the marker lamp.
In some situations, the breakdown of the dimensions does not represent a complete non-functionality of the lights, but simply a weaker glow, which indicates a problem with the supply of current to the contacts. To fix the problem, it is enough to clean the entire contact group in the control unit under the hood, and if that doesn’t help, you will have to check each group leading to the rear light separately.
Why do the indicator lights light up?
This malfunction that you reported is familiar to many Lada owners. To get rid of it, you have several ways:
- First, you need to check the electrical circuit of your car. This is done using a multimeter. The breakdown may consist of an open circuit or short circuit of one of the windings. In this case, it is better to seek help from a qualified electrician if you do not know how to check the network yourself. But if you have knowledge and are confident in your abilities, then detecting a break or short circuit will not be difficult for you.
- Secondly, it would be a good idea to check the functionality of the dimensions themselves by inserting light bulbs of a different rating in their place. Sometimes, if the rating does not match, the corresponding icon may light up on the dashboard. In general, this does not pose any threat to the Lada owner, but such lamps usually fail faster.
Fuse box in a VAZ car
- Thirdly, it is advisable to check the relay responsible for the operation of the dimensions. Perhaps that is where the problem lies. Open the hood, find the fuse box, on the back cover of which there will be a diagram of the arrangement of the elements. Remove the relay and install a known working part in its place. There is a possibility that your problem lies precisely in the relay or in some differences between the original and what is installed on your machine.
In any case, we recommend that you contact a qualified professional. Only an experienced electrician can quickly and easily detect a breakdown.
Additional Tips
Sometimes VAZ 2114 owners are faced with the opposite situation, when the rear lights themselves work, but the indicator on the power button does not: this is almost always a sign of a faulty wiring in the interior panel. You can deal with the problem by removing the entire key block and thoroughly wiping its contacts.
In general, the side lights on this VAZ model should not often fail, since the contact pads for their fuses were specially increased in width in order to ensure a tight connection.
In addition, experts advise that in frequent breakdowns of dimensions there is a malfunction in the mounting block itself or its electrical circuit. Such a problem must be eliminated as soon as possible to eliminate the risk of a wiring fire.
Finally, you should pay attention to the tightness of the entire rear light unit and prevent moisture from getting inside, which can easily cause the lamp contacts to sour.
