The door on the outside of the VAZ 2114 does not open: reasons, how to fix it?

The door of the VAZ 2114 does not close well

Hello.
Help me solve the problem. The back door doesn't close well, you have to slam it hard and sometimes even press it with your body. If you just close it, it seems to close only halfway. I've already changed the lock and adjusted the lug on the body, but to no avail. What could be the problem? Can the seal get in the way? It has become very difficult to open the door - you must first pull the trigger and not pull the handle towards you.

The length of the trigger pull is clearly adjusted; the door opens easily from the inside.

I replaced the outer part of the lock - the gap remained. Should I change the internal one or are there any options?

there is something that appears there over time, the jamb is that the part connected to the external handle begins to move not vertically but vertically + sideways, respectively, the stroke is increased and the trigger stroke is not enough to open the door, the reason is the loosening of the fastening of this garbage to the main part of the lock, in my opinion, on the rivet, but here not sure

So it turns out that the inside is working great, the outside is plowing worse and worse, the adjustment helps a little, or rather max for 1-2 months, then again

Owners of domestically produced cars often need to carry out one or another repair of car parts. One of the common and inconvenient problems is a broken door lock. It forces quick action, as it calls into question the driver’s comfort and the safety of personal belongings.

Central lock VAZ 2114

The central locking VAZ 2114 (hereinafter referred to as CZ) is a mechanism that ensures the simultaneous closing or opening of all four doors in the car. This option is very convenient; it eliminates the need to reach out and lock the doors manually every time. Such centralized control comes in handy when installing car alarm systems, which significantly expands the possibilities and variations of the use of the locking mechanism.

The operation of the lock itself does not depend on whether the car engine is running or the fact that the ignition is turned on. Power is supplied directly from the battery. It is quite common for the system to malfunction.

For example, when the locks of some doors close, but the rest do not. Or the closing process occurs with great difficulty, jamming, or partial failure of the latches.

A situation familiar to many car enthusiasts, isn’t it? There are several reasons for the node to not work correctly; we will look at them in more detail.

7 common faults

Why does the central locking of the VAZ 2114 not work, you ask? Most often, interruptions occur due to temperature changes and humid weather. The first signs are unclear operation of the lock, jamming or incomplete operation.

Below we list the top major breakdowns:

Relay fault. In this case, you can get by with “little expense”; buying and replacing the part is as simple as shelling pears.
Closures This option is already more problematic than the previous one. Now we need a multimeter, we need to use it to test the wiring.
Electrical wiring fault. Here we are talking about breaks and insulation violations. A thorough inspection is required.
Active interference from “L-shaped” springs during traction operation. This malfunction, or rather a flaw, lies in the fact that the spring, which helps the lock mechanism move, over time creates obstacles to free movement. As a result, problems arise with the operation of the central locking system. The solution to the problem is simple and at the same time ingenious - remove all the springs from 4 doors. From the point of view of the performance of the mechanism, the absence of a spring will not affect its operation; on the contrary, the central lock will work with renewed vigor!
Failure of the central locking unit. This situation is not very common, but it does happen. You can check the block using a familiar multimeter. All you need to do is measure the voltage at the CBZ contacts. In the absence of a measuring device, it is possible to resort to the following method: the voltage from the negative terminal of the battery must be transferred to the contacts of the gear motor, after which you can observe the operation of the unit.
Malfunction of the VAZ 2114 central locking fuse. The problem can be caused by the operation of the unit under conditions of increased loads (for example, when the movement of the core is difficult). A fairly common occurrence among fans of all kinds of tuning, changing the stock door trims. As a result of such modifications, the gap under the walker turns out to be smaller in diameter than the factory one. As a result, the operation of the central locking system becomes more difficult, and the load on the drive and electrics in general increases. Therefore, it is not surprising that the fuse blows.
The central locking activator is faulty. One of the most vulnerable elements in the system. Failure is promoted by exposure to moisture, oxidation, and mechanical wear due to friction.

Central locking diagram for VAZ 2114

The system consists of the following components:

mounting block;
8 amp fuse;
4 gearmotors (one in each door, and the one in the driver's door has a contact group);
central locking control unit;
wires (red, black, blue, yellow) and plugs;
rods that are located in each door;
limit switches that signal the current state of the door (open or closed).

Where is the central locking of the VAZ 2114

The central locking system is located in the driver's door, just like the electric drive. If we talk about the system as a whole, it is distributed over 4 doors (in some cases it also extends to the trunk), and the central panel (control unit).

Testing and diagnostics

If your car is equipped with one of the alarm systems, then it is better to start diagnostic measures with it. You should check the operation of the central locking when using the key fob, and when opening and locking using the key. If, during a manual check, the central locking system works correctly, then the reason is the alarm.

Additionally, it would be a good idea to check the battery charge level, since if it is insufficient, interruptions in the operation of many electrical consumers occur.

In general, it is best to check, as they say, along the path of least resistance. That is, diagnose something that does not require significant effort.

And if the fault cannot be identified, resort to disassembling the driver's door and examining the mechanisms along with the electronics.

conclusions

In this article, we touched upon only some of the most common problems associated with the operation, repair and maintenance of a centralized lock.

Despite the fact that the node has plenty of problems, restoring its functionality is not a difficult, much less an impossible task. Usually, to achieve smooth, efficient operation of the system, only practical skills are missing.

After receiving them, you will be able to repair any complexity! If you want to install the central locking on a VAZ 2114 yourself, then here is a video instruction:

Faulty fuse or wires

The second most common reason that the rear door on a VAZ-2114 does not close is a blown fuse. A malfunction can result from either a normal short circuit or a system overload caused by improper operation.

Dangerous factors include incorrectly adjusted rods or dried out lubricant inside the lock, which makes it more difficult for the drives to move the lock rods. The same thing can happen in winter if you try to unlock the doors with the key fob for too long and too often, without allowing the locks to warm up.

adjusting the lock rod;
lubrication of moving parts;
Replacing the fuse, which is inexpensive.

In the same way, wires that are bent at a bend, for example, near a door pillar, can suffer from long-term use. Considering that it is from the driver’s door that five wires go to the control unit and then to the passenger doors, failure of any of them will lead to a cascade of incorrect actions on the part of the central locking system.

Typically, the following steps are sufficient to diagnose this problem:

Removing the rubber protection of the wire bundle.
Carefully palpate each of them separately.
The broken wire will be weakened - it must be pulled out of the bundle.

By pulling out the second end, you can twist them yourself and insulate them, or use the appropriate terminals.

What to do if the central locking on a VAZ-2114 does not work

The central lock on the VAZ-2114 is an excellent device with which you can open or close all the doors of the vehicle with a single movement. Over time, a situation arises when the car stops locking using the central locking or the locking occurs only once. In this case, we can judge that the device has failed.

Causes of malfunction

There are many reasons why the central locking on a VAZ-2114 stops working stably. All existing causes of malfunction can be divided into two subgroups: climatic effects and technical breakdown.

In the first case, the lock begins to work unstably due to the influence of climate, that is, due to very low temperatures, as a result of which not only the lock, but also other systems may freeze. Or, as a result of heavy rains, water got into the central locking of the VAZ-2114. Among the technical reasons, we should note incorrect installation of the device on the car or incorrect configuration of its operation.

But sometimes the device does not work due to prolonged use, which leads to natural wear and tear of some elements. The problem may also be the use of low-quality devices.

How is the central locking system controlled on the VAZ-2114? The algorithm of the central locking operation is that a control pulse arrives at a certain point, as a result of which one relay with power contacts is activated. In one case the car is locked, in the other - vice versa. Central locking activators are connected to relay contact 30, and through closed contact 87, ground acts on both outputs of the activator.

If one or another relay is triggered, then contact 30 will be connected to the positive, and as a result, temporary voltage will be supplied to the activator, which will set the rod in motion, which will either open or close the door. Taking into account the fact that all activators are connected to the central locking system in parallel, one action will be the same for all doors. The locks installed on cars can be electric or pneumatic.

The electric central locking system consists of mechanisms with a single motor, the second, in turn, includes a compressor, tubes and a control panel.

Experts' opinions

Many experts who have encountered the problem that the central locking on a VAZ-2114 does not work argue that all problems with the device should be divided into certain categories. Below we will look at each of them.

Problem categories:

Complete device failure.
Partial lock failure.
Operation malfunctions due to mechanical, electrical or other defects.

If a problem occurs with the central locking, the car owner must independently determine which of the above categories the breakdown falls into. Therefore, repairing a fault should not begin with disassembling a particular unit - it is enough to conduct a thorough diagnosis of the equipment.

Thanks to the diagnostics carried out, the car owner will not only reduce the time spent searching and solving the problem, but will also reduce the monetary costs of repairs. Firstly, the central door lock on the VAZ-2114 works regardless of the engine or ignition. The main thing for the central locker is the presence of a working on-board network.

The serviceability of the BS lies in the correct connection of the vehicle's power terminals to the battery. Experts say that the simplest reason for the malfunction is that the walls of the door tongues are too thick, which cannot move freely through the trim. As a result, the activator is simply unable to close the doors, and at the same time reproduces clicks of completed work.

You can check it in a simple way - just unscrew the locks from the doors and close the car. If all the doors close once, you will have to buy new clamps with a smaller outer diameter.

Diagnosis of alarm malfunction

If the car closes completely from the first, but not from the second, then the problem lies in the electrical alarm circuit or in the control circuit. It happens that the simplest reason for the car not being locked with the key fob is the weak charge used in the battery. It happens that even with the manual method the central locking does not work.

If a vacuum central locking system is used, then during manual testing there will be no sound of the compressor running. With electric central locking, you will hear characteristic clicks produced by the relay. However, the buttons on all doors will remain in the same position. Most often, domestic cars use electrical central locking systems. In such cases, the VAZ-2114 central locking fuse has probably failed.

Depending on the connection circuit used, more than one fuse may need to be replaced. This repair can quickly end.

Fuse burned out

It may happen that the replaced element quickly burns out. When using central locking, the fuse may burn out due to a short circuit or overload. The latter occurs when carrying out any actions on frozen locks using a key fob, and not by manually opening the doors.

If it’s warm outside and frozen locks or frozen grease are out of the question, then the problem lies in a short circuit. In case of a short circuit, you need to look for the cause; the reason may be a broken wire or a poor connection due to oxidized contacts.

In this case, the fuse remains intact, but the signal is not transmitted due to the absence of a control circuit. The activator limit switch may also be broken.

Repairing broken wires

As a rule, most often the wires break off or break in the corrugation of the door. This is due to the fact that the door is constantly opening or closing, and the wire insulation is quite thin. To eliminate the problem of broken wires from the rubber corrugation of the door, you need to slowly pull out one wire at a time that approaches or departs from the central locking unit for power or control.

A broken wire can easily be pulled out of the total mass. You can connect the break using a simple connection using male-female terminals. If the break occurs in another place, it is necessary to test all wiring with a multimeter. When checking, it is worth remembering that voltage will be present on one wire only at the moment of opening, and on the other - when closing the central lock.

One of the reasons for the breakdown may be a malfunction of the central locking unit. To carry out the necessary diagnostics, just use a multimeter and check the voltage of the contacts that connect the activators of the remaining doors.

When checking the remaining doors, the main drive (the one installed on the driver's door) must be unlocked or locked. Simply put, apply current to the contacts of the block.

What to do if the central locking control unit on a VAZ-2114 fails? In this case, it must be replaced with a new one. But it can be restored.

Repair of electric central locking

The central locking system on a VAZ-2114 of this type begins to work intermittently after a while. They will be associated with temperature fluctuations. Most often, unstable operation of an electric central locking system will be observed at low temperatures or high air humidity, that is, in the autumn-winter period.

At first, the mechanisms will jam slightly, then opening or closing will not occur at all. Most often, this problem occurs on domestic cars with pre-installed central locking from the manufacturer. It is better to replace locks with solenoids installed at the factory with central locking systems with motors, which will be more reliable.

If the drive of one door does not work, you should check the circuit to that door. If there is no open circuit, then the problem may lie in a malfunction of the switching relay or a breakdown of the activator control board. Sometimes the solenoid or motor winding may burn out, or the drive gear may wear out.

In this case, it may be necessary to replace the auxiliary drive of the central locking door.

Central locking drive failure

If all the wiring is in good condition, then it also happens that the main activator, which closes the central locking on the VAZ-2114, breaks down. To solve the problem, just purchase a new main door activator. Just remember that you should buy a lock drive that has 5 wires, not 2. Since the five-wire one is installed on the control door, and the two-wire one is installed only on the controlled part.

So, we have looked at the main malfunctions that occur with the central locking on domestic Samara-2 cars.

Step-by-step troubleshooting

Work begins with replacing the key. If it is made of silumin, then in the winter this element freezes quite often. If you apply too much pressure, a silumin key may simply break. Of course, such a part needs to be replaced, but for this you don’t have to buy an assembled door handle for the VAZ-2114, but buy a repair kit. It includes:

two keys;
two leashes for handles;
fastening elements.

Before replacing, you need to pay attention to the appearance of the element - on its reverse side there are two protrusions, one of which, when activated, will press the key, and the second is shortened during assembly so that the ends of the leash do not protrude outward.

Setting up door cards is carried out in several stages. Experienced drivers take a comprehensive approach; they check gaps, re-adjust hinges, and inspect the locking and manual mechanism. There are several options for customizing the doors:

Use a wrench to loosen the internal hinge screws. Tapping with a hammer is carried out so that the structure moves to the desired position. Then the fasteners are tightened back.
To even out the gap, the hinge mechanism is also loosened in two places: top and bottom. The door needs to be raised/lowered by adjusting the height.
The curvature of the metal can only be corrected by straightening.
Adjusting the lock involves loosening the latch, then moving it up/down.
The handle is being disassembled. If the internal screws are deformed, they are replaced.

Other causes of failure

Among other reasons why the VAZ-2114 door does not close well, one can name, firstly, a burnt-out central locking unit - a phenomenon that is not so common, but occurs during the operation of VAZ cars. To determine the breakdown, you will need to “ring” the contacts with a multimeter, while simultaneously applying current to them through the control drive in the driver’s door (turning the key back and forth in the lock). The breakdown is eliminated by replacing the block with a new one.

When choosing a new control unit for the central locking, you should make sure that it has specifications for a specific car model, since analogues or cheap copies may not control the doors correctly after connecting them to the system.

Finally, the cause of all the problems may lie in the contact group of the control drive hidden inside the driver's door. The activator contacts tend to oxidize over time or be destroyed by stress, which naturally leads to a lack of signal transmission.

This unit is also rarely repaired, preferring to purchase a new drive assembly and install it to guarantee the result. The main thing is to pay attention in the store to the correspondence of the number of wires on the activator, which should coincide with this indicator for the old unit.

Lock: repair, unlocking, assembly

If the back or other door of a VAZ 2114 does not open, then you will have to work from the interior. It is important to take care of lighting. To open the door, replace or unlock the lock, the following instructions are provided:

The plugs on the handle of the door element are removed.
Three screws are unscrewed: two on top, one under the armrest.
The cover is removed.
The handle locks are disabled.
The decorative panel comes unfastened.
Electrical wiring is disconnected.
The handle and plastic cap of the lock are removed.

Typical problems with opening doors on a VAZ 2114

If the door does not open either from the inside or from the outside of the VAZ 2114, then adjustment of individual structural elements will be required. The driver's door is subject to wear and tear more than others. This body part can become jammed due to a faulty lock or handle.

Masters claim that the car requires regular care and periodic diagnostics of faults. These actions will prevent breakdowns or extend the life of individual vehicle elements.

“Fucking basin. "

Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.

Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2. Practice on a Demo account (it’s free). 3. As soon as you get something on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY! I also advise you to download the application to your phone, it’s much more convenient to work from your phone. Download here.

Door opening method

If the VAZ-2109 door does not open from any side, then the cause of the breakdown is difficult to determine, since there is absolutely no access to the lock mechanism.

What to do if the door to the apartment does not open?

A somewhat simplified version of the breakdown occurs when the door does not slam shut completely and gets stuck in that position. Then it is possible to reach the latch from the outside with a sharp object.

To open a jammed door, you must first perform the following steps:

When the sash is not completely slammed, try to get to the locking device using a steel flat ruler. It may be possible to open it in a similar way to conventional door locks with a latch.
If the door is completely closed, try to move it to the slightly open position to gain access to the lock. To do this, try pressing the inside and outside handles together or alternately, while simultaneously pushing the door from the inside.
Try opening the back door with a helper, who will press and release it to get it into position while you try to open the lock.

When simple means do not produce results, the door will have to be opened from inside the cabin, which will require removing its trim.

In practice, this is not easy to do, because the casing is pressed by the sash and it is difficult to pull it out without damage. But there is still no other way out: it is better to damage the inner panel than to mutilate the door itself.

To dismantle the decorative panel, you need to unscrew the armrest handle with a screwdriver, and then the storage shelf located at the bottom of the door card. Then the button that secures the lock from above is unscrewed and removed. Lastly, the window lifter handle and the opening handle frame are removed. Now you need to carefully separate the lining from the body using a pair of flathead screwdrivers and another suitable tool. You may be able to remove the trim without visible damage.

Diagnosis of alarm malfunction

The central locking control activator is installed in the driver's door. As soon as this drive is activated, a signal is sent through the channels of the circuit between the remaining activators, according to which the desired action occurs. If an alarm system is installed on the car, the performance check should begin with it. To do this, you need to check the closure both with the key and with the key fob. If the car closes completely from the first, but not from the second, then the problem lies in the electrical alarm circuit or in the control circuit. It happens that the simplest reason for the car not being locked with the key fob is the weak charge used in the battery.

It happens that even with the manual method the central locking does not work. If a vacuum central locking system is used, then during manual testing there will be no sound of the compressor running. With electric central locking, you will hear characteristic clicks produced by the relay. However, the buttons on all doors will remain in the same position. Most often, domestic cars use electrical central locking systems. In such cases, the VAZ-2114 central locking fuse has probably failed. Depending on the connection circuit used, more than one fuse may need to be replaced. This repair can quickly end.

The lock does not work: reasons and actions

First, it’s worth understanding the reasons for the lock’s malfunction. The latter can become clogged with dust or dirt, and the key only compacts all this in the well. To deal with damage, you need to fill the lock with a cleaning mixture, leaving it for a quarter of an hour. In winter, for example, the door may jam if moisture gets into the mechanism. In the cold the door blocks the handle with the keys, so the car must first be driven into the garage to warm up.

If the lock is broken or the door is slammed in the VAZ-2114 from the inside with a key, these methods will not work. You can use the following recommendations:

you need to take an awl and a hard long wire, making a hook at the end;
Use an awl to remove the outer seal of the car glass to create a gap;
it is necessary to lower the wire into the hole until it rests against the latch of the lock;
then you need to turn and rotate the hook, allowing the wire to pass further; if it falls through easily, you should pull it back, thanks to which you will be able to pry the lock;
You should put the seal back and open the car door.

The whole process will take about 10 minutes.
