According to traffic regulations, it is prohibited to operate a vehicle with a non-functioning sound signal. It serves to prevent emergency situations on the road when road users, for one reason or another, do not see each other. Therefore, a sudden failure of this device can play a cruel joke on the car owner. If such a malfunction is detected, do not put off repairing the horn for a long time. We will tell you about the main reasons for the breakdown, most of which you can handle on your own.
Why are fuses needed?
Fuses are elements of an electrical circuit that protect devices from voltage surges. They consist of a plastic case, two contacts and a working element.
The principle of their operation is simple: each element has an operating voltage, and if this value is exceeded, it will immediately burn out and the circuit will open. In fact, the protective component takes the blow, protecting electrical appliances from damage. Its purchase is much cheaper than replacing one or more consumers, which, among other things, can affect the control of the car.
The cigarette lighter in Lada Vesta has a fuse that blows more often than others. Usually the reason for this is connecting devices with high current consumption or several devices at once through a tee.
Wiring is not ok
Have you checked all the elements in the chain, but there is still no sound? This means that the problem lies in the car's electrical wiring. At this stage, you will have to stock up on a tester to “check” the circuits. You need to make sure that there is voltage at the signal button, for which you will have to open the steering wheel cover. If your car does not have airbags, then there will be no problems, but if they are present, the task will become much more complicated. Therefore, in such a situation, it is better to contact a car service so as not to accidentally activate the “airbag”.

Lada Vesta fuse box with description (engine compartment
The required box is located above the battery, on the right side of the air filter. On the cover of the unit you can see warning signs in the form of a crossed out figure of a man with a hose and a lightning bolt.
To remove the cover, bend the two latches at the top and bottom. Be careful because... they are very fragile.

The contents of this mounting block are as follows:

How to set up bluetooth on Vesta
Let's take a closer look at how to enable bluetooth on Vesta.
The Bluetooth connection algorithm in the Lada Vesta station wagon will be something like this. First of all, turn on the smartphone, find the Bluetooth function in it and switch it to operating mode. The next step is to turn on the car radio. When new equipment is found under the name Vesta, they connect to it. The factory password for Bluetooth from the manufacturer is 0000. After connecting the phone to the MMS for the first time, the password will not be needed in the future.
Lada Vesta fuse box with description (interior)
This mounting block is located in a place familiar to drivers - near the left foot. Actually, the space around the trunk opening button and the headlight adjustment control is the cover of the mounting block.
First, remove the plastic clips (nails) that secure the cover to the upholstery. One of them is located on the side of the ignition switch, the other is in the lower left part of the cover (may be absent on some cars). Next, turn the 3 plastic handles at the bottom and pull the lid, releasing all the holders.
Schematic layout
In the interior mounting block you will see the following picture:

How to install a Volga signal
Remove the front bumper (instructions for XRAY, Vesta, Grant, Priora, Kalina, Largus). If it was decided not to remove the standard sound signal (if necessary, you can return to the initial version), then we are looking for a suitable place to install signals from the Volga. Most often they are placed on the front bumper amplifier (on standard mounting bolts), behind the radiator grille or under the headlights on brackets.
Replacing the fuse
In one of the tables, find a device that has stopped working - next to it there will be a designation of a supposedly burnt-out element. At the same time, you will understand where the fuse box is located.
Open the block cover, find and remove the problematic fuse, following the diagrams. The same algorithm applies to a failed relay.
If the contact inside is broken, it means it has burned out. However, this is not always noticeable, so it is better to do a continuity test with a tester.
Before replacing, be sure to find out the cause of the burnout.
The new protective component must match all the characteristics of the old one: the same format, color and current limit designation.
HOW TO CONNECT THE VOLGA SIGNAL
Standard sound signals of LADA cars consume no more than 5A, and Volga horns consume 7A each. In this regard, to connect them it is necessary to use a 4-pin relay. The Volga signal connection diagram is universal for all cars:
Before starting work, it is recommended to disconnect the negative terminal from the battery. All wires are laid in corrugation. We place the relay in a place protected from moisture and dirt. The whole process is also shown in the video:
About the guarantee. If you independently modify the car in terms of electrical components, there is a possibility of refusing warranty service for the car. Therefore, the installation of signals from Volga should be carried out at a service center, where after connection they will be ready to provide a document confirming the quality of work. You can also contact an authorized dealer for such modifications.
Mounting block Lada Vesta in the car interior
The mounting block is located in a familiar place - near the driver’s left foot. To access the relays and fuses:
- turn the plastic handles (3 pieces) holding the unit cover from below;
- remove the lock on the upper right side of the cover;
- Pull the bottom of the cover, disconnect its upper holders to the instrument panel and remove the unit cover.

Addition from car owners
More information about fuses and relays is provided by unnown:
In Table 1, the data of the original relays is highlighted in color. I tried to collect the main characteristics (min required) of possible relay analogues, similar in size, design and characteristics. Where there are empty cells in the table, there is no data. Equivalent R is the actual measurement from the relay contacts. Of course, my data is not a panacea for all ills. Data collected from manufacturers' sources (data sheet) and from online store catalogs.
Before replacing a fuse, you must first determine the cause of its blown. The manufacturer does not allow the use of fuses that differ in current rating from those recommended in the tables below. This can lead to malfunctions in the operation of Vesta's electrical equipment, short circuits and even a car fire!
Attention!
The relay and fuse diagram may differ depending on the configuration and production date of the vehicle. Current diagrams of the mounting block are presented in the operating manual for the date of manufacture of the vehicle (download the manual).
Let us remind you that you can quickly find the necessary material through the contents of Lada Vesta.

Are you satisfied with the operation of the standard sound signal on the LADA model? Are you ready to install a Volga horn? Let us remind you that we previously looked at other methods that can make operating a car more comfortable. For example, installing a gas tank cap bracket or how to make a flip-flop ignition key.
