What to do if the brake lights on a VAZ-2110 do not light up

Driving out onto the road with such a problem is prohibited by traffic rules. This will create problems not only for you and your car, but also for other road users. This model provides monitoring of the status of the brake light lamps; when a malfunction occurs, the signal lamp flashes. However, work stoppage can be caused by other reasons. That's what we'll talk about in this article.

A failure can occur on the way, the service is far away, but you need to continue moving. Therefore, any driver should know the approximate causes of failures and what to do in this case. For in-depth testing, it is advisable to have an autotester or multimeter. In extreme cases, a control light can help out. It is advisable to print and carry with you a list of fuses and the circuits they protect.

Why the brake lights don't light up: how to quickly find and eliminate the cause

Good day everyone and good mood! Surely many drivers have encountered a situation where the brake lights are not on. It may seem to some that there is nothing serious or dangerous in this, and supposedly they can continue to operate a car with such a malfunction without any problems. It's a delusion.

The operation of all lighting equipment on a car plays a huge role. This applies not only to the headlights, but also to the signal lights. Not long ago we discussed the issue of adjusting the low beam. But now the issue is more serious, since it concerns the malfunction of lighting equipment.

In addition to the likelihood of causing an accident, faulty stops also entail the imposition of a monetary fine by traffic police officers. The main emphasis should be on personal safety.

It is recommended to solve the problem as soon as it is noticed. If, in the event of a failure of the sound signal, it is sometimes difficult to cope with the repair yourself, it is most often possible to do without the intervention of specialists and payment for services to car service employees.

Main reasons

Almost all problems related to automotive electrical systems can be solved in approximately the same way. You need to look for a potential or probable cause of malfunctions in the problematic object itself, or understand the system responsible for supplying power.

The situation is exactly the same with devices called brake lights. If they stop working, then you should look for the reason in one of the following points:

• There were problems with the fuse. It has oxidized or completely failed;
• There are faults in the lamps themselves or in one lamp, depending on how many stops are not working;
• The reason lies in the mechanism responsible for turning on the warning signal when the brake is applied;
• In the socket where the stop light is installed, the contacts have oxidized;
• More serious problems appeared related to damage to the wiring.

Based on the stated reasons why the feet may stop working, we can draw a completely objective conclusion. A truly serious malfunction concerns only wear or damage to the electrical wiring. Solving such a problem with your own hands is not always correct.

When the rear brake lights (left and right) or the additional central brake light repeater fail, do not rush to look for an auto electrician and offer him money to fix the problem.

There is a high probability that you will be able to do everything on your own. You will only need a standard set of tools for a motorist, as well as an understanding of how the lighting equipment in general works in your vehicle. Start with the most likely and fairly simple to solve possible malfunctions. Only if it turns out that the problem is bad or damaged electrical wiring, then it makes sense to visit a good car service center. It is better to entrust such tasks to experienced craftsmen. The main components for restoring the operation of brake lights on your own, you will need a spare working lamp, a control unit or a multimeter, as well as suitable tools.

It would be a good idea to study the owner's manual and understand how to get to the stops on your car.

Fuse

The first place to start is by searching for the mounting block in which the fuse responsible for the brake light is located.

Moreover, each machine has its own electrical circuit and specific location of fuses.

These can vary significantly depending on the vehicle, such as:

• VAZ 2110;
• VAZ 2107;
• Toyota Rav 4;
• Ford Fusion;
• VAZ 2114;
• VAZ 2115;
• Ford Focus;
• Chevrolet Lacetti;
• Lada Granta;
• Hyundai Accent;
• Renault Logan;
• Hyundai Solaris, etc.

A blown fuse quite often causes the failure of a number of equipment, including lighting devices. Check fuses visually and using a multimeter.

But there is a simple and effective way to check that takes a minimum of time. To do this, start the engine and hold down the horn button. This is not suitable for all car models, but on many vehicles the same fuse is often responsible for the sound signal and brake lights.

If this is not the case, we continue our search further.

Brake lamps and their sockets

Next, you should switch to the brake lights themselves. In most cars, to gain access to the feet, the luggage compartment is opened, the rear light bulb is removed, after which you can get to the feet themselves.

But the dismantling process may differ on different brands and models. Here, start from your car specifically; if necessary, look for hints in the operating manual. There are examples of cars where you can get to the brake light without removing the rear optics at all. You still have one main task ahead of you. It consists of gaining physical access to the faulty device, the lamp and the socket in which it is located. Not everyone can try to determine the problem by eye. Here it is better to take a different route.

The optimal solution would be to use new, similar lamps instead of potentially faulty ones. Therefore, you will have to buy a light bulb in advance and screw it in. If you can't find a lamp of a similar size, use a marker or turn signal repeater. Make sure these conditional controls work first.

When everything worked after installing the new lamps, you found the reason. You can confidently buy new matching stop lamps, replace old ones and reassemble the unit in reverse order.

It is extremely important to take into account one feature. Some modern cars have such a principle of operation of brake lights, in which when one car brake light fails for one reason or another, the second one automatically stops functioning. That is, sometimes checking one lamp does not give a result, since in fact the chances are 50/50 of replacing the burnt lamp, and not the one that simply turned off in tandem.

If replacing the light bulbs did not give anything, check the sockets themselves. It happens that they oxidize, this breaks contact, and the device does not turn on, although power is supplied to it. Also make sure that the socket is connected to the vehicle wiring. If necessary, the contacts are disconnected, cleaned with fine-grained sandpaper, and then returned to their place. Even during this procedure, it is recommended to apply a special lubricant to the contacts after cleaning.

One more thing. When checking the sockets, it is also worth taking new light bulbs. It happens that due to oxidation of the cartridge, the lighting device itself fails. That is, in fact, 2 malfunctions occur simultaneously.

Problems with the switch

The brake light on a car lights up the moment the driver presses the brake pedal with his foot while sitting behind the wheel. When pressed in this way, the force is transferred to a special mechanism. It is popularly called a frog. It is also a limit switch and it is also a classic brake light switch.

There are 3 main reasons why a frog or limit switch may not work:

• contacts have oxidized;
• carbon deposits appeared;
• corrosion has formed.

Despite the slightly different processes, the essence of the problem is the same. It can be eliminated by stripping the frog, or by replacing the stop switch.

If none of the options are suitable, there is a high probability that the problem lies in damage to the vehicle's electrical wiring. Here it’s up to you to decide whether to try to resolve the issue on your own, or seek help from qualified specialists.

Considering the complexity of the electrical circuits of modern cars, a better solution would be to visit a trusted auto electrician. But the final choice is yours.

Common problems with brake lights

There may be several reasons:

• blown fuse;
• faulty sensor;
• frayed or broken power cord.

The most common cause is a blown fuse responsible for protecting the signal light circuit. This fuse is located on a block built to the left of the steering column. This capacitor can withstand a current of 7.5 amperes, as evidenced by the inscription on it. It is located in the bottom row, fourth from the right edge.

If after replacing this circuit element the problem has not been resolved, other possible causes of failure should be considered.

The next troubleshooting point is to check the brake light sensor. To do this, you need to check whether voltage is entering and exiting the sensor. In this case, you need to use a control lamp. If the lamp does not light up when connected in front of the sensor, then the problem may be in the wires going to the sensor. If the lamp works before the sensor, but not after, then the problem lies in this part. You can also simply disconnect the input and output of the sensor and close it “directly” using a copper wire; if after these manipulations the lights in the brake lights light up, then the reason is precisely in the sensor. The sensor cannot be repaired, and the only way out is to replace this part with a new one.

Damaged wires may also be the cause, this will be especially noticeable if the just replaced fuse blows out - this means that the wire is frayed and there is a contact to ground. If the fuse blows without pressing the brake pedal, the wire before the sensor is damaged, and if it blows after pressing, the wire after the sensor is damaged. If there is no voltage, perhaps the wire is simply broken and does not short to ground. When troubleshooting, you should pay special attention to bends and possible areas of damage to the wires.

The next cause of problems is burnt-out LEDs in the brake light; there have been cases when both burned out at once. To replace the light bulbs, you need to remove the flashlight board by squeezing it from the sides and pulling it slightly towards you. Next, you should visually inspect the light bulbs; perhaps a visual inspection will already answer the question about the reason for the non-working brake light. After this, you should replace the old lamps with new ones.

Methods for troubleshooting

Troubleshooting is not a complicated process and even novice car enthusiasts can do it (the author of the video is Avtoelektika VC).

Using a multimeter, you need to test the wiring. Damaged or torn sections should be replaced intact or soldered. If there are traces of oxidation processes on the contacts, they need to be cleaned.

If the LEDs burn out, they need to be replaced in pairs. If the breaker fails, it must be replaced with a new one, as it cannot be repaired. Before replacing, turn off the vehicle's power by removing the negative terminal from the battery. Then disconnect the power wires from the breaker. Next, you need to loosen the lock nut and unscrew the main nut securing the switch to the bracket.

Replacing the brake light switch

Before installation, the new frog should be checked for functionality. This can be done using an ohmmeter. We connect the device to the device and measure the resistance. When the contact is closed, the resistance should be zero. If you press the rod, the contacts should open; the resistance in this case tends to infinity.

Why do the brake lights on the VAZ-2112 not light up or work, what should I do?

On all cars of the Tenth Family, the power lines for the lights contain many elements. There are lamp health relays, switches and fuses. Therefore, if the brake lights on a VAZ-2112 do not light up, you need to check the entire chain. But the reason may look simple: sometimes the lamps do not turn on because the socket does not contact ground. Circuits are easy to analyze, but finding the cause of a breakdown is difficult. Let's look into the details.

If one of the lamps does not light, it is simply replaced. See the example in the video - you need a P21 W

Additional Tips

Before each trip, especially over long distances, you should check the functionality of all lighting equipment, including brake lights. In order to reduce the likelihood of breakdowns along the way, you need to periodically check the condition of the sockets and bases of the rear light bulbs, and periodically clean them of oxides and dirt.

In case a breakdown does occur, you should always have an additional set of light bulbs and 10 amp fuses in your car, as well as a multimeter to check them.

Standard version of the brake light operating diagram

Power is supplied to fuse F17 from the battery, then the current goes to limit switch contact 11, and then, if the limit switch is closed, a circuit is formed with the filament of lamps 7. But note: part of the circuit is relay K1, more precisely, its contacts 5 and 4.

Basic network diagram

If the brake lights do not light up, on the VAZ-2112, as on all Tens, check one fuse. It is called F17 and is located in the mounting block to the left of the driver.

Main mounting block

It is important to know: voltage is always present at one of the fuse terminals. Check it out!

A few words about the “serviceability relay”

The lamp health relay is called K1, and it is the largest in the mounting block. If you remove this relay, then when you press the pedal you can dial the voltage at terminal 5 (but not 4). Look at the diagram again, and it will become clear what we are talking about.

The largest relay in the block

All relay contacts are numbered. Check the voltage at the block terminals:

• 6 – “mass” potential;
• 2 – voltage “+12”, but only after turning on the ignition;
• 5 – “+12” by pressing the pedal;
• 4 – the terminal rings like a ground tap.

If the potential “0” is not generated at terminal “4,” it means that the lamp filaments are burnt out or there is a break in the wiring. Now consider something else: the ground potential has been detected, but the lamps do not light. This is where suspicions of a short circuit arise.

Fault localization

Understanding the operating principle allows you to determine exactly why the brake lights may not light up:

• The fuse has blown. In the diagram, the fuses are marked with the letter F (from English - Fuse) and the serial number of the seat in the fuse block, for example, F3;
• poor contact at connectors;
• the light bulbs have burned out, but since the lights are connected in parallel, the likelihood that 2 lamps will burn out at once is extremely low;
• poor contact on the negative terminal of the lights. In this case, problems may begin not only with the feet, but also with the lighting of the remaining lamps in the lanterns;
• Damage to the negative track in the lamp board. From the total mass directly to the brake light lamp, the minus goes along a special path on the board. The path may collapse from water or mechanical impact;
• malfunction of the brake light switch, the so-called frog;
• broken wiring, oxidation of contacts.

Troubleshooting algorithm

To detect a fault in the electrical network, you will need a multimeter or a tester, which you can make yourself

Previously, we told you how to use a multimeter, so we won’t focus on that.

The sequence of searching for the cause of the breakdown:

• Check the fuse for the brake light circuit. The location diagram of the fuse links can be found in the repair and operating manual for your car; often the symbol of the protected circuits is located on the back of the cover covering the fuse mounting block. If the installed fuse of the required rating immediately blows, there is a short circuit (short circuit) in the circuit. Please note that the fuse can protect not only the feet, but also other circuits. Installing a fuse with an increased rating is fraught with the risk of a car fire;
• If oxidation is detected on the terminals, clean the contacts mechanically or use an aerosol contact cleaner.
• Having turned on the ignition first and holding the brake pedal depressed, check whether there is power on the positive wire that goes from the limit switch to the rear light connector. If there is power, there is a malfunction in the lights themselves;
• check whether the positive signal is coming from the mounting block to the limit switch. If + comes, but when you press the brake pedal it does not appear on the second terminal of the limit switch, then the problem is in the “frog”;
• If there is no + at the limit switch terminal, examine the circuit up to the mounting block. If the wire is intact and securely fastened in the connectors, then the problem is in the mounting block.

We turn on the brake lights forcibly

Relay K1 is successfully replaced with a pad with jumpers. In Fig. 1 just shows its diagram. If there is no such platform, you can temporarily close contacts 4-5. First, check everything mentioned above.

Have an observer watch what happens to the lamps. Press the pedal with one touch and release it. If the lamps do not turn on, check that the fuse is working properly. It's burned out, which means you're looking for a short circuit.

How to and how not to check the “0 Volt” potential

Let’s agree right away that we only work with a voltmeter. Voltage “+12” is caused by connecting one probe to ground. The presence of potential “zero” is checked differently: any of the probes is connected to a terminal with positive voltage, and then the second probe is connected to the wire being tested.

How to connect a voltmeter

Consider the error: one probe is connected to ground, the second to the terminal being tested, and vol. Here they conclude that there is a “mass” potential, but this is wrong! If the contact with ground is broken, the device will also show “0”. That is, the number “0” does not contain information.

Where to start checking

The power supply circuit for the brake light lamps is protected by 7.5 Ampere fuse F17, but in addition to them, it also powers interior lighting lamps, ignition switch illumination, a clock or a computer. In the event that all this does not work, you should check this protective device. If a fuse is blown, try to determine the cause of the failure before installing a new one. If there is a short circuit in the circuit, then burnout will occur indefinitely until the cause of the short circuit is found and eliminated.

Next, you should check the serviceability of the brake light switch, which is installed on the brake pedal bracket. One of the two suitable wires must have on-board voltage. It can be checked with a device or a test lamp. If there is power, check the operation of the switch. To do this, disconnect the wires from it and connect them together with a piece of wire, after which you can see whether the lamps are on or not. The appearance of light will confirm the failure of the switch; its absence suggests continuing the search.

Wiring test for non-working brake lights (ground test)

Let's look at the basic diagram: the brake lights and the reversing lamps have a common ground pin. If contact with this pin is broken, the reverse lamps will not turn on. Well, brake lights too.

Connector for connecting “internal” lights

On the left side there is a connector through which the wiring goes to the fifth door. The connector has black and red wires. Check the voltages on them. Most often the ground on the black wire does not ring. But maybe the connector itself needs to be cleaned.

Usually, if the ground breaks, another pin is used - the one that is connected to the glass heating coil.

If the “plus” does not come to the red wire, we check the “frog”. It's simple here:

1. Disconnect the connector with two wires from the limit switch;
2. Using 17mm wrenches, loosen the two nuts: holding the lower nut, rotate the upper one;

Removing the frog brake

By the way, one of the connector terminals receives a voltage of “12 Volts”. Check it!

If all the steps do not lead to results, there is only one thing left: contact a qualified electrician. We wish you success.

What else to pay attention to

Very often, the appearance of such malfunctions occurs due to the fault of the rear lights, or more precisely, in the places where the connectors with wires and lamp sockets are connected. Using a measuring device or a test lamp, check the presence of power at the rear light connectors with the brake pedal pressed or the wires on the switch connected to each other. If it is missing, you should carefully check the condition of the wiring harness.

Oxidation of contacts in connectors or sockets of electric lamps can be removed using available means. It is not advisable to use sandpaper for this, even very fine sandpaper. Alcohol-containing liquids are best suited for this, as they remove the resulting oxidation.

Installation process

Ready-made kits usually contain an installation diagram for the VAZ 2110. However, you should understand that adjustments may need to be made during the process.

Before starting installation work, you need to make sure there is space for them. If it is not provided for in your model, then you should think about it and decide on it yourself. It is recommended to do this through the front bumper.

The installation procedure is as follows:

1. At the very beginning we lay out the wiring for the fog lights. It is laid in the same way as the main wiring - along the wing, through the left side (under the hood).
2. After this, you need to supply power to the button, which will need to be placed on the dashboard. According to the standard, power is supplied from the fuse on the right dimensions. However, you can go the other way by connecting power to the light switch. You can take power from the output to the dimensions, but this method should be used last, since the battery may discharge prematurely if you forget to turn off the PTF.
3. We connect the plug together with the headlights. If the lights do not light up, then there was some error in the circuit. Each component of the network should be carefully checked. Often the problem is in the relay. To identify it, you need to make sure there is a click; if there is none, the relay should be completely changed.

It is quite simple to check that the headlights are set correctly and are working correctly: drive out onto the road and turn on the headlights.

If the light is directed slightly downward, but illuminates both the road surface and the side of the road equally well, everything is installed correctly.

The reverse lights of the VAZ 2110 do not light up - what to do?

Leaving your garage one evening, you notice that nothing lights the way. The situation, frankly speaking, is unpleasant and makes you think about it. After all, the rear lights of a VAZ 2110 should be on in normal mode. This means that there is some kind of malfunction that needs to be found and eliminated. Who knows what the reason is, we will have to figure it out. If the reverse lights of a VAZ 2110 do not light up, then, in all likelihood, it is possible that they have simply burned out. Maybe it's a simple failure of a fuse or sensor.

Signs of trouble

If the odometer suddenly refuses to work, and the speedometer works jerkily, or “lies” regarding speed and mileage, these are direct indications that the speed sensor or its drive is failing. It is also possible that there is a problem in the electrical circuit, the connector is failing, the pinout is mixed up, if the operation of this system has been interfered with, etc.

In addition, an indirect indication of a malfunction may be that the car stalls at idle (although there may be other reasons for this).

Naturally, if the speedometer begins to give deliberately false readings, and the “CHECK ENGINE” light is on on the dashboard, then the reason is the speed sensor.

Reasons why the reverse lamps do not light up

It is not difficult to see that when the reverse light on a VAZ2110 does not light up, the reasons can be of a very different nature. But be that as it may, everything needs to be corrected, and for this the cause must be eliminated.

To do this you need to do the following:

• It is necessary to determine the condition of fuse No. 19. It is designed for a power of 7.5 A. Its location is the rear light board of the VAZ 2110 mounting block under the dashboard.
• Next you need to make sure that the light bulbs are working properly. If it turns out that there are no problems with them, you need to check the reverse sensor.

In the latter case, the question of its location may arise. When viewing the car from the front, it is on the right side. If we consider it in projection in the direction of travel, then it will be located in the gearbox, in its lower left part.

Car enthusiasts gave this sensor its name, calling it a frog. It is nothing more than a regular switch. The gearbox has a hole where this sensor is placed. Its working surface looks inside the box. From the outside, in the normal position, the contacts are open. When reverse gear is engaged, a special shield presses on the working surface of the sensor, which leads to the closure of the contacts. This provides power to the reversing lights. The sensor differs from a conventional switch in its special design. The device is sealed and resistant to significant mechanical loads.

CIRCUIT BREAKERS

To protect against voltage surges and other influences on the electrical component, a side light fuse is also included in the circuit along with the light bulbs and the button. At the moment of overvoltage, it burns out, but due to this everything else in the circuit remains intact. It is usually located in the engine compartment, where in the VAZ 2114 there is a place for a whole fuse block for all electrical networks in the car.

Since all of them have markings, we can easily find the parts that we need: F10 is responsible for the safety of the lamps on the left side of the car, and F11 for the right. Thus, in the event of a failure of one half, for example, when the rear left indicator does not light up, the right side of the car will remain operational and will do its job. And if the size fuse blows, then replacing it is, in principle, quite simple - this is considered the simplest malfunction of this kind.

Checking the functionality of the sensor (frog)

When you manage to find it, you need to check its performance status:

1. The wires connected to it must be disconnected.
2. A tester is connected to their ends. The device is switched to “resistance” mode and the measurement is carried out.
3. Then reverse gear is engaged.
4. The ignition is switched to the on state.
5. The instrument readings are taken.

The device may show 0 Ohm. This means that there are no problems with it. If there are other indicators, it needs to be replaced. This must be done not only when the VAZ 2110 does not have reverse gear on, but also when the lights are on and reverse gear is not engaged.

Algorithm of actions when replacing a sensor

Changing it is not particularly difficult, but you need to do the following:

• To replace the car, you need to put it in a pit or drive it onto an overpass.
• If there is engine protection, it must be removed.
• You should first prepare some kind of container for the oil, since the moment the sensor is unscrewed, a certain part of the oil will leak out.
• Then you need to unscrew the wires that are connected to the sensor.
• The old sensor must be removed and a new device installed in its place.
• The oil that leaked out during the sensor replacement process must be added to the box.
• Next, the wires are connected. They must first be wiped dry to remove any oil that has got on them.
• Then you should start the car and check for light from the bulbs when reverse is engaged.

Such measures are one of the options for eliminating the problem in which the reverse lights of the VAZ 2110 do not light up.

Lamp replacement procedure

If not a VAZ 2112, then the light bulb may have burned out and needs to be replaced.

The replacement process consists of the following steps:

1. Disconnect the negative terminal on the battery. Replacing high and low beam lamps is the same, the only difference is the holes in which they are installed.
2. To access the element to be replaced, you need to remove the rubber plug.
3. Next, you should disconnect the wire block from the light bulb.
4. Then you need to find the retainer that holds the springs and carefully remove it from the grooves.
5. Now you can remove the light bulb from the socket.
6. The next step is to insert a new light bulb.
7. We assemble in the reverse order of removal.
8. To replace, you need to remove the casing by unscrewing 4 bolts. The lamp is unscrewed by grasping the socket and turning it counterclockwise until it stops.
9. Next, we insert a new light element and reassemble it.

1. Remove the rubber plug.

Lower the latch down.

3. Remove the element from the socket.

After installing the lamps, you need to check their functionality.

Other causes of rear light malfunctions

But it may also happen that the reverse light on the VAZ 2110 does not light up, and the sensor is not the reason for this. Then it might be a nutritional issue. It also needs to be checked. When turned on, no power is supplied, which means you should look for a break in the wiring. Check the area where the fuse is connected to the sensor and the section where the sensor is connected to the lamp.

When reverse gear is engaged on a VAZ 2110, the white light bulbs should light up at the same time.

Their purpose is to perform the following functions:

1. parking is much more convenient with lit lights;
2. burning lights give pedestrians an indication that the car is about to reverse;
3. Reversing lights are used to prevent emergency situations.

If a problem arises in which the reverse lights do not turn on, you can try to fix the problem yourself, or contact a car service center.

The problem can be resolved on your own, since the reasons for this, as a rule, are the following situations:

• The light bulb just burned out. In this case, it must be replaced. But before replacing, it is recommended to check the integrity of the wiring in order to eliminate the possibility of a situation in which a short circuit occurs.
• The reason may also be that there is no voltage on the flashlight board.
• The fuse that is installed to protect against short circuit has blown. It just needs to be changed. The fuse doesn't just blow. This means that this is due to some problem in the circuit. To do this, you need to “ring” each section and determine the location of the problem.
• Contacts may burn. Because of this, the light bulb will stop lighting. In this case, the burnt contacts should be cleaned.
• It is possible that the electrical cable is damaged. A malfunction can be detected by visual inspection or instrumentally using a multimeter.
• If the car is operated for a long time in conditions of high humidity, this can lead to oxidation of the contacts. As a result, the reversing lights will no longer work normally.
• The reason may lie in the incorrect operation of the gearbox mechanism. It is this mechanism that should lead to the inclusion of the rear lights.
• The malfunction may be caused by a broken reverse sensor. It is not at all necessary to take your car for professional diagnostics. You can check its performance yourself. To do this, the sensor must be removed and the ends of the wires connected to each other. If the light starts to light up, then the problem is in the sensor.

Malfunction of the lights themselves

If during the check from the fuse box to the limit switch no problems are found, then you should move on. Now you should test the wiring from the second limit switch connector to the stop connectors with a tester. If it is working, then you need to check the board. The printed circuit board on which the taillights are mounted is not ideal, and is one of the biggest problems of all VAZ cars.

Its tracks often burn out or peel off, causing the lights to stop working. This problem can be solved in two ways - either re-solder the tracks (which can be done with a regular soldering iron, although not in road conditions) or replace the board with a new one (most motorists choose the second option).

Tail lights of VAZ 2114

Another reason why the VAZ 2114 brake lights do not work may be oxidation of the lamp sockets. In order to eliminate this problem, it is enough to clean all contacts from oxides that have appeared on them.

This is best done in one of the following ways:

• small grit sandpaper;
• WD-40 solution;
• kerosene;
• purified gasoline (“galosh”).

You should absolutely not use gasoline or other solvents to clean contacts.

The last option for faulty stops is the light bulbs themselves. It makes no sense to give any detailed advice here - you just need to replace the burnt out light bulbs with new ones.

By following all the tips listed above, the car enthusiast gets the opportunity to check the entire electrical circuit of the brake lights, starting from the fuse box and ending with the bulbs in the lamps. Thanks to this, the guarantee that the fault will be accurately detected and eliminated is 100%.

Modification of the rear lights of the VAZ 2110

Often, to fix the problem, it is necessary to modify the rear lights of the VAZ 2110. To do this, you first need to dismantle the old reverse lights. If the lamp simply burns out, then replacing it will not be a problem.

It won't be difficult to replace a blown fuse. But replacing a failed sensor is much more difficult. The algorithm of actions has already been announced within the framework of this article. But to replace it, you will need to drive the car into a pit or overpass. Without this, fixing the problem will be problematic.

Having read this review, the reader now has an idea of ​​what could cause the reverse lights to turn off. If practical skills allow, this problem can be solved independently. Anyone who is not very familiar with the structure of the car and does not have practical repair skills is recommended to contact a service center, where qualified specialists will help solve the problem.

PRICES OF COMPONENTS

There is also a separate section for prices for all the parts that may be needed when repairing this part of the car, because if the side lights on a VAZ 2114 or the fuses have blown, they will still have to be replaced with new ones. In any case, all the components are quite cheap, all we might need:

• Marker lamp;
• Fuse;
• Power button;
• A whole fuse block.

Today, an ordinary white light bulb costs up to 30 rubles; of course, the price depends on the individual pricing policy of a particular seller. Individual fuses can be selected for up to 50 rubles, unless, of course, you want to install a higher quality option. Button, if you look for exactly the same one as the original one, you will have to pay up to 300 rubles. In some situations, more serious problems may arise and you will have to change the entire unit, this is quite an expensive proposition, together with all the wires it will cost up to 1000 rubles.
