Rear light

In this article we will look at the main reasons why turn signals do not work on such VAZ models as: 2108, 2109,21099, 2113, 2114, 2115. All these models belong to the SAMARA family and have similar electronics. And in general, this article is suitable for all cars, because... The reasons for the malfunction are the same for everyone.

Repairing turn signals in many cases is a simple task. The main thing is to find the cause of the problem.

General information about turn signals

If you read the history of the creation of cars, then initially this part was not included in the package, and drivers installed it additionally for a fee.
In modern cars, turn indicators are often placed on the headlight unit or next to it if they are front ones. The rear turn signal is mounted near the headlight. Repeaters of this necessary part can be placed on wings and mirrors. There is a technology for duplicating mirrors using diode lamps. This is now considered the most progressive. The turn signal consists of the following parts:

mechanical drive (for starting and shutting down);
switch (to connect the lamps to the power source);
relay, for closing and opening a circuit after a certain time.

Some cars have a very good functional solution - triple flashing when touched quickly; drivers really like this quality.

If you don’t have one, you can install a device that will increase the number of signals.

When the turn signal is activated, you hear a characteristic sound. In modern cars it can be changed to a more pleasant one. This car part gives a bright yellow, sometimes mixed with orange, glow. On American models, they are sometimes made red, which leads to an increase in emergency situations on the road, as they are confused with stop signals.

Traditionally, they are included as an indicator of breakdown - “emergency mode”. A turn signal is a kind of language of communication between drivers on the roads. They can be shown the undesirability of overtaking and other circumstances.

Turn signals fired on time are an indicator of your ability to drive a car and control the situation on the road.

Frequent malfunctions of turn signals and emergency lights, and how to fix them

If the turning lights stop working, you need to carry out diagnostics and try to eliminate the identified faults. When you can’t do it yourself, you should contact a car service.

Turn switch

To identify such a breakdown, check the functionality of the contacts when the switch is in different positions. Inspect plastic or metal elements. In this case, melting or carbon deposits may appear. Then the relay clicks, but neither the right nor left turning mechanisms work.

To eliminate the breakdown, the switch is removed and disassembled. After cleaning the contacts, the part is assembled in the reverse order. A photo taken in advance will make the job easier.

Turns relay

A faulty element requires immediate repair. The part is inexpensive, so they buy 2 pieces in reserve. The relay is located in the fuse box in the engine compartment or inside the passenger compartment. The operating instructions help determine the location of the part you are looking for. The mounting block contains an image describing the purpose of the switches and relays.

Faulty lamp blade wiring

Finding the location of the wiring break is made difficult by the fact that the turn signals are connected to the rear parking lights. The cables run throughout the entire cabin, and the lamps are installed on the tailgate.

Most often, electrical wiring is damaged in the following places:

under the thresholds in the area of the front passenger and driver's seats;
in the adapter that supplies wiring to the trunk lid;
in the headlight sockets.

If the left or right turn signal is faulty, you should check the contacts of the light bulbs with a multimeter. If voltage is present, tighten the lamellas of the socket into which the base is inserted. Modern manufacturers supply cars with LED elements.

Despite their long service life individually, when assembled in a line they often burn out. The problem is solved by replacing the design component.

Hazard switch

If this part breaks, the lamps start on both sides simultaneously. On some cars, the rotary control relay is located in the hazard warning light switch. A new button is inexpensive, so it is recommended not to repair it, but to replace it.

Malfunction or software failure of the body control unit

In some models, such as the Lada Priora, the functions of switching the indicators in question are transferred to the body control unit. The advantage is the possibility of centralized control, the disadvantage is the complication of auto repair. To eliminate the breakdown, disassembling the unit is required. Such repairs are performed only in a car service center.

Turn signals do not work on VAZ-2114

Problems with turn signals can occur both in VAZs with a carburetor engine and in models with an 8-valve injector. It gives more power to the engine and other benefits, while making troubleshooting more difficult.

A turn signal may not work well most often due to burnt out electrical contacts or if the integrity is damaged (a problem with the sealant). The instrument panel may indicate that there is a problem. You will notice a discrepancy between the signal and the turn button: the presence of a flashing headlight.

This malfunction is considered simple, but relatively common. If you figure out why this happened, then carry out the repair yourself and without any problems. The electronics here are simple and accessible to any driver who is minimally familiar with the operation of electrical circuits and has attended physics classes at school.

Let's look at the main causes of the malfunction and how to eliminate them:

If there is no turn indicator signal, then in 90% of cases you need to replace the electrical relay or check how the contacts are connected to it. The relay is indicated by the symbol K1. Possible depressurization and liquid ingress. If after replacing the relay with a new one, the malfunction remains, then you need to carefully inspect the fuses. Perhaps one of them has burned out and needs to be replaced; it is better to check the entire unit.
Don't forget to check the quality of fuse F12, as well as how it functions with everyone. Check the functionality of the switch itself, there may well be a malfunction there.
Sometimes the emergency warning button fails. If this is the case, we can easily replace it with another one that works normally.
If the turn signal lamp does not turn on, check the functionality of the device. She could simply burn out.
If it is impossible to turn off the turn signal, a simple action is taken: the switch is replaced.
Frequent blinking indicates problems with the lamp; it is better to replace it. If after replacement the result is the same, then the contacts have probably deteriorated (oxidized) and need to be replaced or cleaned. Sometimes it is a matter of failure of the tracks on the block.
Dim glow. There are several reasons for this phenomenon: a mismatch in the power of the lamp required for a given turn signal. In this case, it is enough to purchase a lamp with the required parameters and replace it.
Atypical relay sounds. With such a malfunction, the turn signals do not turn on according to your wishes. In such a situation, as a rule, the electrical relay should be replaced. It would be ideal if you purchase an original car from the factory that matches the model, so you will achieve long-term good performance.
If the right turn signal does not work, then you need to carefully examine the right headlight. Its electrical board often malfunctions due to oxidation, therefore, the supply of electric current is disrupted. As a result, problems are possible with both the relays and fuses, and accordingly the turn signals stop working.

Power button

Sometimes the alarm system stops working due to the failure of its activation button. When removed, sometimes its defects are visually visible. In order for the light fixture to function again, the part will need to be replaced.

If trouble happens on the road, you can temporarily restore the functionality of the emergency lights without having to buy a new button. To do this, you will need to remove it and disconnect it from the block. Using a paper clip or wire, make a jumper that will close the contacts of the block. The part must be positioned so that the cutout on one of the faces is at the bottom. Insert the jumper into the middle socket in the left row of contacts. Secure its second end into the lower socket of the adjacent row. If everything is done correctly, the hazard warning lights and turn signals will work as normal.

Turn signals are dim

Checking the serviceability of the turn relay

And so let’s look at what to do if the turns of a front-wheel drive VAZ, except for the 2170 Priora, do not work. The operation and troubleshooting of which was discussed in the article “Prior Turning Relay”.

First, make sure that the measuring instruments and control lamps on the instrument panel are working. If they do not work, then check the fuse.

If the devices are working properly, turn on the hazard warning button and check that all the lamps in the direction indicators are blinking. This will allow you to divide the circuit into two parts and speed up troubleshooting.

If the alarm does not work when turned on, then it is necessary to check the serviceability of the turn and alarm relay and the presence of power at its terminal 49. The pin designation is marked on the bottom of the relay, next to the contact legs.

We remove the relay, which is marked in the form of a triangle on the top of the case, from the mounting block, and in the vacated socket, using a test paw, check for the presence of a plus on pin 49. We connect the test lamp to the ground or minus of the battery, and with the other end we touch pin 49, when If the hazard warning button is on, you do not need to turn on the ignition. Lack of power indicates a faulty fuse, alarm button or broken wires, contact tracks of the mounting block and poor contact in the connectors.

If there is a plus on the terminal, then connect terminals 49 and 49A with a copper wire. If the connecting wires and connectors are in good condition, all the direction indicator lamps should light up. This indicates that the turn signal and light signaling relay is faulty. If the lamps do not light up, but there is a plus on pin 49, then there may be a short circuit in the signal lamp circuit and the fuse has blown. A short circuit can also cause the relay to fail. In this case, check the serviceability of the fuse, and if it blows, eliminate the short circuit in the signal lamp circuit.

Checking the hazard warning button.

If the hazard warning lights are working, then the turn signal and hazard warning relays are working properly, but the fault may be in the hazard warning light button. First, check the plus, as described earlier at pin 49 of the relay, with the hazard warning button off and the ignition on.

If there is no plus, then you need to check the serviceability of the alarm button. To do this, you need to remove the button from the socket by prying it off with a thin screwdriver or remove the instrument panel visor. In the contact connector of the button, use a test lamp to check the presence of power at pin 2 (the numbering of pins on the button near the contacts) with the ignition on. If there is no power, repair the broken wire from the instrument panel to the button. If there is power, connect pin 2 to pin 5 in the button socket, with the ignition on, and turn on the direction indicators of either side. If the warning lights on this board light up, replace the faulty hazard warning button.

Fuse

To understand why the emergency lights on the VAZ 2114 do not work, the first thing you need to do is check the fuse responsible for it. It is installed in the mounting block under the hood of the car on the left side. This fusible element is designated F2 . To speed up the search, you can use the electrical diagram number fourteen, where its exact location is drawn.

A burnt out or broken part can sometimes be identified visually by the presence of plaque or damaged elements. You can also check the serviceability of the fuse using a multimeter. There are two diagnostic methods.

For the first method, the measuring device must be switched to voltmeter mode and the car's alarm system must be turned on. By connecting the probes of the device to the outputs on the fuse element, determine the presence of voltage on them. If one of them does not have it, the part needs to be replaced. It is inexpensive and can be changed literally with one movement of the hand. You can even make a replacement on the go. Especially if there is an auto parts store nearby.

You can also diagnose the element with this device in ohmmeter mode. To do this, you need to remove it from the car and attach the probes to the outputs. If the resistance is zero, the part should be replaced.

Often the fuse turns out to be serviceable, but its contacts are oxidized. This happens due to dampness and time. In this case, you should simply clean them.

It is worth noting that some motorists with such a breakdown begin to check the K2 relay. But there is no need to waste time diagnosing it, since in this case the turn indicators would not light up either.

Turn signals do not work on VAZ-2114

Signs and causes of malfunctioning turn signals and emergency signals

These elements of the lighting system stop working due to:

Blown fuse box in the passenger compartment. This problem occurs often. If the car is equipped with a relay that regulates the operation of lighting devices, the cause should be looked for in it. Depending on the make of the car, this part may be located at different distances from the fuses. The diagram attached to the instructions helps you find it.
Short circuits in the on-board network. Because of this, the turn lights do not light up and the hazard warning lights go off instead. The system stops responding to user commands. To detect a breakdown, you will need a multimeter. The driver must understand the electrical circuit.
Failure of the lighting source. In this case, replace the burnt out light bulb.
Broken wiring. This is what owners of outdated VAZ car models face. If the wires are laid in places where there are moving parts, the braid will fray over time. The integrity of the electrical circuit section is compromised.
Failure of the turning light control element or steering column switch. In this case, a thorough diagnosis of the control buttons is required.

The following signs help determine the presence of malfunctions in the optical system of the machine:

The turn signals are on continuously. The symptom appears when the relay breaks down, in particular its electromagnetic component. It often gets stuck in one position, causing it to be unable to return to its original position.
The blinking frequency of the turning lights has changed. The source of this malfunction is not only the relay, but also the wrong type of light bulb. When purchasing new lighting products, take into account the value declared by the car manufacturer.
The optical system is not functioning. Not only the lights do not light up, but also the indicators on the center console. The clicks that occur when the indicators are turned on are not observed. There are many reasons for such malfunctions.

How to check the lighting devices in the Chetyrka?

The verification procedure is carried out as follows:

First you need to make sure that you are using a working fuse. The fuse box is located in the engine compartment, in the compartment between the engine and the windshield, opposite the driver's seat. Bend the latches and remove the cover, then carefully inspect the inside. It contains a diagram that will help you figure out which fuse is responsible for the operation of a particular equipment. Remove the fuse responsible for the functionality of the software and carefully inspect it - if the fuse inside is melted or damaged, the fuse must be replaced. But even if there is no visible damage, you need to insert another one with the appropriate rating into the socket of the removed fuse.
If this does not help restore the software, then check the relay, it is located in the same block. Typically, the turn signal relay has a hazard warning symbol on it, you need to pull it out and replace it with a working one. To do this, it is not necessary to buy a new relay; you need to pull out another working device and install it. If the emergency lights and software do not work, then we continue checking.
Now we need to diagnose the light bulbs, but such a check will be required if only part of the turns does not work. Open the hood or trunk and remove the headlight protection, then remove the light sources from their seats. Install a known working device in place of the removed lamp and check how it works. If there are no changes, we move on.
It is necessary to check the integrity of electrical circuits. To do this, you will need a test lamp with two wires connected to it. One end should be connected to the negative of the battery or the body of the Four, and the second wire is connected to the contact of the electrical circuit being diagnosed. If, as a result of the connection, the lamp begins to light, this indicates that the section of the wire being tested is in good condition. The remaining circuits are checked in the same way. If you find a place where there is no current, then this indicates that there is a fault between the place being tested and the last point where the voltage was. Damaged wires must be replaced.
You also need to check the quality of contacts on all electrical circuits. Check the contacts in the mounting block, on the base in the vehicle's optics, on the light alarm button and on the steering column switch. Often the cause of problems is oxidation; such contacts must be cleaned or replaced.

Dubious savings

After my post about the mysterious current consumer, I suddenly got a subscriber!) Thank you, friend! This post is for you!

Once upon a time there was a man who drove a Korean SUV. Somehow the wires in the fifth door broke, someone repaired them, but my friend drove on, not knowing grief. But again the wires frayed and his fuse blew. One fuse had blown - a new one was installed in its place, and that one had blown. Our hero got tired of this, and he installed a “bug” jumper in place of the fuse. She did not burn out, but honestly passed current through herself to a short circuit. And the wiring with broken insulation began to heat up, and strongly - melting its insulation from the trunk to the mounting block.

As a result: replacement of the wire (disassembly of the interior trim and the fifth door, search and replacement of the burnt-out wire, resoldering of the wires at the bend, assembly. The amount turned out to be quite large. If I had contacted the beetle before installing it, it would have been much cheaper. Moral: be careful with the electrics your car, in case of malfunctions, contact specialists, do not engage in amateur activities such as replacing fuses with fireproof jumpers.

Dim burning

If the turn signals on a VAZ 2115 do not work or the light bulbs are dim, then you need to: 1. Check the light bulbs for compliance with their power; 2. Clean the mass. Heading 2: Clicking of the turn signal relay If you encounter frequent clicking of the indicators, then you should look for the problem in the additional unit, or even more precisely, in the relay contacts. They could oxidize over time and become unusable, or simply not fit tightly. Perhaps the relay turned out to be defective. In this case, it is recommended to install a factory relay.
