The performance of key components and mechanisms in your car is the basis for its safe operation. Such important devices installed on board domestic vehicles include a sound signal.
The Volzhsky auto industry, releasing new models of its cars, equips them with standard signaling devices of type 20.3721. Similar signals are also installed on the Lada Granta. But due to its low sound quality and frequent breakdowns (especially after moisture), many car enthusiasts strive to install a higher quality and “melodic” signal on the Grant.
As an alternative, Volga signals on Granta are especially popular, tested by time and the experience of many drivers. The signal from the Volga actually sounds louder and is more reliable in operation, but replacing the standard signal with a Volga signal requires the driver to have some knowledge of electrical equipment. If you follow the rules for installing electrical wiring, the installation of signals from the Volga to Grant will be done quickly and as correctly as possible.
Replacing the signal on Grant - from simple to complex
There can be a great many reasons why the signal on Grant does not work:
— a break in the current-carrying signal wiring harness; — poor contact with the vehicle ground; — malfunction of the signal itself or its unstable operation; — the signal activation button is broken.
Every car enthusiast can find out why the signal on Grant disappeared on his own. To do this, you only need attentiveness and the correct sequence of actions.
Despite the ease of installation of signaling devices, many car enthusiasts have a reasonable question - how to install signals on the Grant without damaging the electrical equipment of the car?
Everything is very simple. To replace a faulty or poorly functioning signal on a Lada Granta, first of all, you will need to disconnect the minus terminal from the power source. Although they say that replacing the sound signal on a Grant without removing the bumper is possible, it is better to remove the bumper itself to avoid damage.
Next, you need to gain access to the left radiator mounting post, because it is where the signal to the Grant is normally installed. Using your hand, squeeze the latch of the signal contact connector and disconnect the supply wires.
Using a socket set to “13”, unscrew the nut securing the signal and remove the sound signal itself. Installation of signals on the Grant is carried out in the opposite order of removal. Most often, car enthusiasts install horns from a Volga car.
Loud sound, excellent quality and the absence of wheezing characteristic of the Grant signal have established Volgov signals as the best alternative to standard devices. And in fact, installing Volgov signals on Granta is no different from installing a native signal.
Signal pair: installation features
When the question arises about what signal to put on the Grant, you should proceed from the experience of advanced car owners. On forums dedicated to automotive topics, you will find a lot of advice regarding choosing a signal for Grants.
Some advise installing only Volga signals, others like signaling devices from Hella, and still others are happy with the standard signal. There are the same disagreements regarding the number of signals, but the overwhelming majority recommend using a two-tone signal.
Installation of a two-tone signal on Grant is carried out in the same order as installation of a standard signal. Two wires are connected to the positive wire, which will power both signals, and the mount works great as a ground. In this case, it is extremely important to ensure reliable contact at the terminals of both signals and at the junction of the vehicle ground and the signal itself.
Tips for motorists
Installed sound signal (type 20.3721 or SZ-3-1), on a Lada Granta passenger car (Lada Granta), one tone. It is located behind the radiator trim on the left side of the car. The production of sound signals, unfortunately, is not of constant quality, which leads to their failure. Some Lada Granta owners have already replaced them a couple of times.
The sound signal is activated through the K8 relay, which is located in the mounting block in the cabin to the left of the steering column. The electrical circuit of the sound signal is protected by fuse F20, rated for a current of fifteen amperes. This fuse also protects the cigarette lighter, trunk lock and diagnostic connector circuits. Most often, it fails due to the fact that drivers use the cigarette lighter socket as a socket, inserting plugs of a smaller diameter into it, which leads to a short circuit in this electrical circuit. And since the fuse has blown, the horn will also not work, and the trunk will not open.
If the sound signal fails, in addition to the fuse in the mounting block, you also need to check the operation of the relay. This can be done in two ways. Or you remove this relay and install a similar known-good relay in its place. However, it should be noted that removing the sound signal relay from the socket is quite inconvenient. The second way to check this relay is to use a jumper, which you close contacts 87 and 30 in the relay socket. If the signal works, it means it is working, and the relay will have to be changed. And if the signal does not work, then the relay has nothing to do with it. Then you will have to remove the bumper of the Lada Granta to get to the sound signal and disconnect the plug from it to check whether voltage is supplied to its terminals.
To do this, you will need a tester or test lamp, preferably 21 watts. We measure the voltage at the contacts of the block and if it is there, then you will have to remove the sound signal itself and replace it with a new one or open it and look for the cause of the failure inside the electrical signal circuit. If there is no voltage, then you will have to ring the wires from the horn block to the mounting block.
Another possible problem is related to the sound signal, when it turns on independently, without the driver pressing a button to turn it on. If you cannot immediately find this reason, then in order for the signal to stop working, remove relay K8 from the socket.
To prevent failure of electrical equipment and devices, the car's electrical wiring contains an element called the Grant Liftback fuse box.
If it is installed incorrectly, then a normal short circuit in any of the electrical components will lead to a fire in the wiring, which can cause internal damage and even spontaneous combustion of the machine. Therefore, the installation of this element requires a special approach and caution.
Common causes of malfunctions
All that remains is to talk about why such situations arise and what the motorist himself needs to do in order to restore the functionality of the horn.
Since a car signal consists of a fairly large number of components, the reasons must be looked for in them. To do this, it is good to understand the device, design and principle of operation of the warning system.
- Blown fuse. A trivial but common problem. The fuse is located in a special block. Look for information in the instruction manual. Sometimes simply replacing the fuse is enough;
- Burnt out relay. Since the horn is powered through a fuse and a relay, the latter is also necessarily checked in the mounting block, and changed if the problem is with it;
- Broken horn. If everything is fine with the relay and fuse, the problem may be in the device itself. To check, you can take the element and directly supply power through the battery. When the horn is working, the signal appears;
- Short circuit. The place to start your search is with the safety socket. And then move along the chain;
- The contact ring on the steering wheel is worn out. It will need to be replaced if necessary;
- The clamping contacts on the column are worn out. A characteristic feature of domestic cars;
- The contacts have oxidized. Check the contact group for rust or signs of oxidation;
- The winding on the horn has burned out. The problem is solved by replacement;
- Violation of electrical contact;
- The cable on the steering wheel where there is an airbag is broken.
In the vast majority of cases, and if desired, most of the possible problems can be solved on your own.
But for this you need to know how to use a tester or multimeter. These are truly integral tools that help determine the source of problems, check the condition of the electrical circuit, the power supply to the horn and other points.
In the worst case scenario, you will have to carry out a comprehensive replacement, or even install a new horn or a new steering wheel. But this happens quite rarely.
Most often, motorists are faced with banal oxidation and contact failure due to rust. The problem is resolved by stripping the contacts and then reconnecting them.
If for some reason you cannot find the problem yourself, or do not dare to take on the task of correcting the current situation yourself, contact experienced specialists. They will quickly carry out diagnostics, find the source of trouble, and fix the breakdown. But directly for your money.
Have you ever encountered a failure of the steering wheel signal? How did you troubleshoot the problem and what was the cause of the problem? Did you manage to do it yourself?

Why the sound signal stopped working: where to look for the reason
Hi all! I can’t say that car horn malfunctions occur very often and everywhere. But we cannot exclude a situation in which the signal does not work.
Car horns are safety features. Moreover, they must be present in all vehicles and be in good condition. This will allow you to give a timely signal to other road users, inform about the approach, and prevent collisions and other dangerous situations.
But at some point it happens that the sound signal located on the steering wheel suddenly stops working. It is necessary to address the issue of diagnostics as soon as possible, since it is dangerous to continue operating the car with a non-working horn.
How it works
Before looking for reasons and finding ways out of the current situation, it would be useful to understand the principle of operation and structure of the signal.
Structurally, the horn includes a fairly extensive list of elements, among which are:
- anchor;
- kernel;
- core;
- tungsten contacts;
- frame;
- capacitor;
- relay;
- activation button;
- resonant disk;
- membrane;
- contact relays, etc.
When the driver presses a special button, current flows through the winding, thereby magnetizing the core and tightening the armature. Together with the anchor, the rod moves, bending the membrane.
Due to a special nut, the contact group opens and the electrical circuit breaks. Next, a number of horn elements return to their original position. At the same time, it closes the contacts again, and current flows to the winding. Opening occurs the moment the driver presses the button.
For the driver himself, everything is much simpler. He just presses a button and the machine emits a loud, characteristic signal.
Similar systems, having different signals, but identical operating principles, are used:
- on Niva;
- on Gazelle;
- VAZ 2110 cars;
- VAZ 2107;
- VAZ 2114;
- Renault Logan;
- Renault Sandero;
- Lada Priora;
- Daewoo Lanos;
- Lada Kalina;
- Chevrolet Lacetti;
- Skoda Fabia, etc.
If the sound signal suddenly stops working, or shows obvious signs of malfunction, action should be taken immediately.
The motorist should know what the signs of problems are and the main reasons for the horn’s failure to emit warning sounds.
Symptoms of problems
How can you even determine that the horn is not working or has some kind of malfunction? It's actually extremely simple.
There are 2 main signs of problems with a car horn:
- The signal doesn't work at all. When you press the button, the driver, like other road users, hear absolutely nothing. This is a clear indication that the system has failed;
- The signal appears periodically. There is also a slightly different situation when the horn does not go off with every press. That is, they pressed it once, everything works, but when you try to honk again, the horn goes silent, there is no reaction to the press. Then the situation repeats itself.
