The signal does not work on the VAZ 2107: repair from A to Z

The sound signal, also called a horn, plays an important role in ensuring safety on the road, as it makes it possible to attract the attention of other road users. The article discusses the situation when the signal does not work on a VAZ 2107: causes of malfunctions, methods of elimination, the possibility of its repair and replacement.

Possible malfunctions: signs and causes

In order to understand the reasons why the horn does not work, you need to understand the VAZ 2107 signal circuit:

The circuit consists of the following components:

sound devices;
mounting block;
jumpers for contacts installed in place of the relay;
signal switch.

The sound signal is activated by a button located in the center of the steering wheel.

There is a contact ring on the steering wheel, and a spring-loaded contact in the area of the steering column switches. Modern alarm devices are equipped with an adjusting screw for adjusting the volume and a built-in relay (in the mounting block, the relay outputs for the sound signal are short-circuited with a jumper).

no sound when pressing a button;
The sound does not turn off or turns on randomly;
hoarse, quiet or intermittent sound.

The audio system carries low voltage current, so the quality of the connections is important. If there is a large amount of oxides and rust on the contacts, then the passage of current becomes difficult. Klaxons require a powerful current of at least 4-5 A.

It is necessary to carefully monitor the cleanliness of connections and terminals, otherwise repairs will be needed constantly. Since the car body acts as a minus, and oxidation settles on the plus, special attention should be paid to stripping the terminals on the positive red wire.

The negative branch of the chain is the longest, so it is most likely to have a break. To determine the cause of the malfunction, you need to connect the gray-black wire coming from the signaling device to the body, and the positive wire directly to the battery. Then the ignition is turned on. If the sound appears, it means there is a break in the minus value. If there is no sound and the positive terminals are cleaned, then the device has failed.

If the sound signal on a VAZ 2107 does not work, the following malfunctions are possible:

fuse is blown;
contacts and terminals have oxidized;
the relay has failed;
the connections on the jumper, if present, have oxidized;
the paddle on the steering column relay broke;
development of a slip ring.

After diagnostics, the faults found should be eliminated (video author - Alex Life).

Methods for troubleshooting

If a fuse or relay has failed, they must be replaced with new parts. If the slip ring is worn out, then it is unlikely that you can repair the steering wheel, since the slip ring is difficult to find on sale. In this case, the most reasonable thing is to replace the steering wheel.

If the horn makes hoarse sounds or turns on intermittently, you should use a multimeter to check whether the battery is charging and the voltage is flowing to the terminals. If everything is fine with the power supply, the reason may be in the sound device itself. There is a screw on the horn body to adjust the volume. It should be rotated until the wheezing disappears and the sound becomes loud.

If adjusting the volume does not help eliminate the wheezing, you will have to disassemble the device to clean the contacts. You can also replace the membrane. Sometimes hoarse sounds appear when starting the engine. In this case, it is necessary to check the condition of the breaker contacts and the top plate. The contacts should be thoroughly cleaned and the plate replaced if necessary.

Signal interchangeability

If the alarm device cannot be repaired, it must be replaced with another one.

All modern horns can be divided into two types: pneumatic and electromagnetic (video author - Russia 24).

In the first type of sound signals, the air flow moves from the compressor through a pipe, which, under the influence of vibration, begins to make sounds. Pneumatic devices differ in the shape of the tube and the power of sound. The frequency range of the audio signal covers several audio zones. Several pipes can be installed, but they require a powerful compressor.

The feasibility of self-repair

Self-repair is possible if the driver is well versed in electrical engineering. Car enthusiasts who do not have such skills can replace a fuse, relay or clean the terminals.

If the contacts are not oxidized, but burned out, then it is easier to install a new signaling device. If you know how to make a signal on a VAZ 2107, you can do the repairs yourself - this will give you the opportunity to gain experience in electrical repair work and save money at the service station.

If the signal on a VAZ 2107 is lost, it should be repaired as quickly as possible, since its malfunction increases the risk of an accident.

In addition, according to traffic rules, operating a car without a sound signal is prohibited. Therefore, it is impossible to pass a technical inspection with a faulty horn.

This video demonstrates how to diagnose and repair the horn on a VAZ 2107 (the author of the video is DamirBikmetov).

Does the sound signal on the VAZ 2110 not work?

Every car must have a working horn. Thanks to the horn, the driver can prevent an emergency situation on the road and avoid a possible collision. But it often happens that the horn refuses to work. For what reasons does the sound signal on the VAZ 2110 not work and how to fix this problem - read below.

There are several signs of a malfunctioning sound signal on a VAZ 2110 or 2112:

The sound signal has disappeared. The driver presses the steering wheel or the corresponding button located on it, but there is no beep.
The beep appears and disappears. When the driver presses the steering wheel, the signal may start to work, but then immediately disappears.

There may be several reasons why the horn refuses to function:

One of the most common reasons is the failure of a safety device. In this case, the integrity of the horn itself will not be compromised, which greatly simplifies the repair procedure.
Failure of the horn itself. If after replacing the safety device the sound does not appear, you can try to check the functionality of the horn by dismantling it and directly connecting it to the battery. If the device is working, then when connected to the battery it will begin to emit a corresponding signal.
The reason may also be a short circuit in the vehicle's on-board network.
Another cause of the problem may be worn out clamping contacts located on the steering column. This problem often occurs in the cars of our compatriots. In any case, the clamping contacts wear out over time due to use; this cannot be prevented. As an option, you can try to increase the service life of the contacts; to do this, they need to be treated with graphite lubricant from time to time.
Worn slip ring on the steering wheel. As stated above, there is no escape from wear and tear, so sooner or later every car owner will face such a problem. As in the previous case, you can try to increase the service life of the slip ring by applying graphite lubricant to it.
Oxidation of contacts on the steering wheel. With prolonged use, deposits will begin to accumulate on the internal contacts, which makes it impossible to transmit the impulse to activate the horn.

Methods for troubleshooting

If the horn circuit is broken and the horn stops working, then there are several options for solving the problem:

First you need to diagnose the safety device. If this part is burnt out, then you just need to replace it with a new one; the device is located in the mounting block. The replacement process will not take much time; any car enthusiast can cope with this task. If replacing the fuse gave results, but after some time the horn stopped working again, then most likely the reason lies in voltage surges in the on-board network. Overload contributes to accelerated burnout of the fuse element, so you will have to look for the source of the load and solve the problem. To do this, use a multimeter or seek help from an electrician.
If the horn itself malfunctions, the device must be replaced. If diagnostics by direct connection to the battery do not produce results, then most likely the reason lies in the device itself, which needs to be changed.
Short circuit. To diagnose, you will need a multimeter and a little experience. Using a tester, you can find a short circuit, but if you have never encountered such a problem before, it is better to seek help from specialists.
If the clamping contacts or slip ring are worn out, then the failed elements must be replaced. It is not a fact that you will be able to buy new contacts or a ring, so most likely you will have to change the horn assembly.
Another reason why the horn does not work is oxidation of the internal contacts. Over time, as mentioned above, dirt and deposits accumulate on them, which leads to the obstruction of sound. You can try to disassemble the steering wheel of the car, then clean the internal contacts and assemble the steering wheel (the author of the video is the channel Alexander Amochkin Kolomna AAK).

If you are faced with the problem of a non-working horn, then you will probably be wondering how to replace it:

First of all, you need to remove the steering wheel. To do this, remove the trim and unscrew the bolts that secure the steering wheel.
After the steering wheel is removed, you can clean the contact tracks, perhaps this will help solve the problem. Make sure that the wire contacts in the column are as clean as possible .
Unscrew the two screws located under the plastic cover. After dismantling the cover, you will be able to see the contact plate; there is a possibility that the problem lies there. Clean the contacts and check the signal functionality. If the horn does not work, then using a 24mm wrench you will need to unscrew the nut, but you do not need to unscrew it all the way.
Next, the steering wheel itself must be pulled towards you; this will require some effort. You can try to move the wheel by tapping it from different sides. When you feel that the steering wheel has given way, the nut is unscrewed completely.
After dismantling the steering wheel, we proceed to removing the horn. There is a module located under the grille of the radiator unit; it must be removed; to do this, unscrew the nut to 13 and disconnect the connector.
Install a new one, replace the steering wheel and check the operation of the horn.

Is a Volga horn good?

Is it possible to use a signal from the Volga in the “ten”, how to install it and how to connect it yourself? In the VAZ 2110 it is allowed to install a Volga horn, and the latter can be either old or new model. There is no particular difference between these details, except that the tonality will be slightly different. And, of course, the cost. But keep in mind that installation by simply replacing the device will not work.

The bottom line is that two cables are connected to the standard device - one with a negative output, which comes from the button on the steering wheel, and the other with a positive one. The latter is permanently connected; it also powers the ventilation device of the radiator unit.

But in Volga devices, only one cable is used - positive, since the mass in this case is supplied through the body, that is, from the attachment to the vehicle body.

In addition, you must also take into account that both systems use different current consumers - the standard options require no more than 5 amperes, while the Volga ones require 8 amperes each. The result is 16 amperes (video author - Master Bruce).

Accordingly, to correctly connect a product from Volga to a VAZ 2110, you will need a four-pin relay; you have several options for installing it:

in the vehicle interior, in the mounting block with fuses;
in the engine compartment, but in this case, please note that the relay should be securely insulated to prevent moisture from entering.

The feasibility of self-repair

So does it make sense to repair the horn yourself? If we take into account the recommendations described above, then the repair is advisable only if the car owner is as careful as possible when performing it.

After all, during the repair work, there is a high probability that an inexperienced car enthusiast will damage the wiring in the unit or connect the contacts incorrectly.

Therefore, if you have never encountered a repair procedure before, it is better to entrust this matter to specialists or simply replace the horn assembly.

VAZ 2107 signal does not work

The VAZ 2107 signal does not work, such a nuisance is sometimes observed, although this should not be surprising, the car is designed in such a way that various parts that have served their service life periodically fail. A car horn, or as it is also called a “horn,” is a device that synthesizes sound. The first, and the simplest and most common reason is a breakdown of the switch; also, the relay, which is responsible for turning on the sound signal, may burn out.

First of all, when the VAZ 2107 signal does not work, it is necessary to establish the exact cause of the breakdown and check the relay, contact terminals, and the integrity of the electrical wires of the circuit. The contacts are easily restored by regular cleaning, and the wiring and sound relay, in extreme cases, can always be changed. Sometimes the VAZ sound signal does not disappear completely, but works periodically, or begins to make an incomprehensible wheezing sound. In this case, you should check the power supply and battery.

If everything is normal with the voltage, then you need to pay attention to the device itself. On the signal housing of the VAZ 2107 there is a special screw with which you can make sound adjustments. It must be rotated until the signal stops wheezing and becomes loud.

If these manipulations with the position adjusting screw do not correct it, you will have to disassemble the horn to get to its breaker. It is necessary to thoroughly clean all contacts on it, and, if possible, replace the membrane. Sometimes the VAZ signal works adequately, but begins to wheeze only when the power unit is started in the car. In this case, you need to check the top plate and the condition of the breaker contacts; they may need to be replaced. If the contacts of the breaker are simply burnt out, it is easier to install a new signal than to repair it; it seems that this solution will be the most correct. One way or another, there is no point in postponing the repair of the sound signal, because in addition to the inconvenience when driving a VAZ car, the car will not pass a technical inspection at the traffic police.

VAZ 2107 steering wheel signal does not work

Tips for motorists

From a road safety perspective, the horn plays an important role in preventing road accidents. On a VAZ-2107 car, depending on the modification, two sound signals of different tones can be installed behind the radiator of the cooling system, or one sound signal, which will be installed behind the front radiator trim.

To put it into operation, a horn button is installed on the steering wheel, and in the mounting block there is a fuse F7 (20A) and a horn relay RS-528. But on some VAZ-2107 cars this relay will not be installed, and in its place there will simply be stand jumper.

If there is no sound signal, troubleshooting should begin by checking the fuse . You need to look not only whether it has burned out or not, but also the condition of its contacts. The horn relay, if your car has one, can be checked quite simply; when you press the horn button, it should click; if the click is not heard, you will have to replace it.

The sound signals themselves can be checked without removing them from the installation site. To do this, disconnect the wires going to it and connect the horn directly to the battery . If there is no signal, a possible malfunction may be burning of the contacts located inside the audio signal housing or a violation of its adjustment. You can adjust the tone by turning the adjusting screw located at the back of the horn housing and gently turning it in one direction or the other.

Another reason for the signal not working may be the power button itself . You will have to remove it and check the condition of the contacts. Malfunctions that arise in the operation of the sound signal on a VAZ-2107 car can easily be corrected by the driver himself.

Cars are equipped with two sound signals: one high-pitched and the other low-pitched. The sound signals are located in the engine compartment and are mounted on a bracket attached to the left radiator shield.

↑ Scheme for switching on sound signals on a VAZ 2107

1 — sound signals; 2 — mounting block;

3 — sound signal switch on the steering wheel; P3 - relay for turning on sound signals; A - to terminal “30” of the generator

↑ Determining audio signal faults

The causes of sound signal malfunctions may be the following:

the switch does not work or is stuck,
The sound signal or the signal activation relay is damaged.

↑ What to do if the sound signal does not work?

To detect a malfunction, check the reliability of the wire connections, the condition of the switch and relay contacts. If necessary, clean the contacts. Replace faulty horn, switch or relay with new ones.

If the signal strength decreases or wheezing appears, check to see if the battery voltage is low. If it is normal, then adjust the signal by turning the screw on its body in one direction or another until you get a loud and clear sound.

If the adjustment does not eliminate wheezing or the signal operates intermittently, then disassemble the signal and clean the contacts of its breaker.

When assembling the signal, it is necessary to install the same gasket between the membrane and the signal housing so as not to disturb the gap between the core and the armature.

A car horn is a very important detail that ensures traffic safety and helps prevent collisions with other cars and a collision with a pedestrian who suddenly runs out onto the road. Different car models use different horn designs, but in our article we will talk about the original VAZ-2107. From it you will learn on what principle the signal works, what modifications of it can be used in these machines, and also what to do in the event of a breakdown.

Setting up and replacing the signal on a VAZ-2107

The horn can be adjusted without dismantling. This is done this way:

The sound elements are adjusted one by one. You should disconnect the power from the element that is not being configured at this moment.
By rotating the adjusting screw, you can achieve an extremely clear and loud sound signal.
The 2nd sound signal is configured in a similar way, turning off the 1st one in advance.
When replacing a damaged sound signal, the power wires are disconnected from it, and the nut holding the element to the bracket is unscrewed.
All that remains is to install the new signal in reverse order.

In the event that the sound element is functioning, but the signal refuses to work, you need to start looking for the area where the electrical circuit is broken. First of all, we examine the fuse, the rating of which is 16 A or 20 A. It is located in the supply unit F7. This fuse is used to connect the electric motor of the cooling radiator.

When the fuse tends to blow frequently, it is time to increase the rating to 25 A, thereby allowing you to compensate for the load during the simultaneous operation of the sound signal and the fan. If the fuse is intact, the sound signal relay on the VAZ-2107 is examined. To do this, you need to pull it out from the trigger point with a plastic extractor located in the mounting block and check it with a multimeter.

Well, first of all, take a tester and see if there is voltage at the terminals coming to the signal. results to us.

if there is a jumper, then you have an incoming minus to the signal and a constant plus, you need to put a relay instead of the jumper, the wire that goes to the signal, one of them, there will be a constant plus on it, we isolate it, the second wire, there will be a plus on it from the relay, we hook it to the pipe, we connect the second wire from the pipe to ground.

In short, if I put a relay instead of a jumper, then when I press a button on the steering wheel. the relay clicks the signal does not buzz (((

Added after 2 minutes 53 seconds:

and if you measure the voltage on the contacts between which there is a jumper, then when you press the button nothing appears there. and voltage appears only on 2 side contacts and on the top. but on the bottom - no. Why nulf there is a jumper that closes the left contact and the bottom one.

because the usual beeper signal is weak, the one that does not buzz, and the six-tone signal requires the installation of a relay, and on the first cars they installed it, but then, as always, they simplified it and installed a simple beeper, but the CY remained the same, it happened to me too, and the first thing After I picked up the car from the dealership, I installed just such horns, I began to study the diagram and realized that it was a simple modification. As always, the improvements did not improve the car, but worsened it.

Yes, by the way, I didn’t understand something, from tens of them these are six-piece pipes.

Did I understand these correctly??

I just bought a single horn from a dozen and installed it. and I took off the double and stood like that! Well, he seems to be writing normally!

Added after 46 seconds:

nope, not like in the photo. The regular one is the same as it was, only a single one. in the store it says VAZ 2110
