VAZ 21043 fuse diagram

Information on the “five” schemes is intended for self-repair of a car in case of minor problems with electrical equipment. The electrical circuits are divided into several blocks (for ease of viewing via a computer or phone), there are files in the form of a single picture with a description of each element - for printing on a printer. Years of production of this model: from 1979 to 2010. At the end of December 2010, AvtoVAZ stopped producing it due to low demand for the VAZ-2105 model. By this time, 2 million cars had already been produced.

VAZ 2105 fuse block diagram, complex or spot replacement

If individual elements of automotive electrical systems refuse to cooperate, an experienced car owner will definitely begin searching in the fuse box. Most likely, one of them, the one responsible for a specific block, has burned out. Due to the fact that the VAZ 2105 fuse diagram is quite simple, finding the problem (if it really lies in a burnt-out fuse element) is easier than ever. It is enough to look into the diagram and find a blown fuse “on the ground”.

In the VAZ 2105, the fuse box (also known as the mounting block) is located under the hood, near the windshield on the left side, when viewed from the driver’s seat. However, it all depends on the year of manufacture of the car (on the first “fives” the fuse box was located inside the cabin, on models of later production it moved under the hood). You can check either “on the ground” or by reading the user manual in more detail.

In order to check the fuses for their functionality, it is enough to remove the cover (by the way, the diagram is always applied to the inside of the cover so that it is always, so to speak, at hand). A screwdriver is enough to remove the cover.

On cars whose year of manufacture is quite distant from the current one, you should check the correct installation of fuses - first of all, from the point of view of compliance with the permissible current in the circuit controlled by the fuse. Unlike the “kopek”, in the “five” the permissible current strength varies for the fuses - from 7.5 amperes for the rear fog lights and signaling device to 20 in the circuit of the rear window heating elements, electric motor and sound signal. More powerful fuses, which inexperienced drivers often try to install, only lead to quick breakdowns, and the cost of repairs turns out to be much higher than the price of even several dozen fuses.

With a lack of knowledge in the field of automotive electrical engineering, the VAZ 2105 fuse box diagram may seem too complicated, although, of course, this is absolutely not the case. In this case, it is better to replace the entire fuse box (especially if you are sure that this is the problem). Replacing the unit as a whole is a little more expensive, but you won’t have to understand the intricacies of the location of each fuse. At least this time.

Block parsing

The VAZ mounting block can become unusable at any time. Therefore, you should always have a fuse diagram in your car in case you need to replace them.

If a certain electrical unit fails, you should not immediately take on the electric motor or spark plugs. There is a high probability that the malfunction has occurred in the safety block.

In the old-style VAZ 21053, the unit is located directly under the dashboard next to the left door, that is, inside the cabin. In the new VAZ 21053, the safety block is located outside under the hood, closer to the windshield, on the driver's side. The latest models of the “five” are most often equipped with an external fuse block.

To open the unit, you need to remove the cover by pushing it upward. On any cover there is a diagram of the VAZ mounting block, which reflects the location of the fuses with a description of the electric current for each of them. In older VAZ 2105 models, the most precise installation of each fuse in accordance with the required current strength is important.

Fuse and relay diagram 2105

Until 1988, the fog lamps in the rear lights and the fog lamp warning lamp were protected by fuse 17 of the mounting block. Since 1988, they began to be protected by a separate fuse, which is located in a plastic case in the wiring harness near the car's fog light switch.
