Today, every car, regardless of type, is equipped with special protection for all electrical systems. This protection is called a fuse. They are installed so that in the event of a short circuit or malfunction, the system can turn off via a fuse, thereby protecting itself from breakdown. Fuses are used for every electrical circuit, from a small light bulb to an engine's ignition system. More important engine systems are equipped with special relays, they protect various pumps, electric motors and other powerful sources of electricity consumption.
The fuse is a small structure consisting of a plastic casing with a fusible element inside. If a short circuit occurs, the thin contact melts under the influence of current, which interrupts the electric current. The simplest electrical fuse is a thin copper wire inserted into a circuit. If the upper limit of the supplied current increases, the contact begins to melt and interrupts the flow of electricity. Here there is a description of all fuses and relays for VAZ 2113, 2114, 2115 models of injection and carburetor types, old and new models.
Interpretation of fuses and relays of injection models
The main electrical fuse module 2114-3722010-60 is located under the front engine compartment. This arrangement allows for quick access to all electrical systems of the car.
Block location
Please note that the location of the electrical fuse module may depend on the type of equipment and year of manufacture of the vehicle. As a rule, this is the upper right part of the engine compartment, under the front windshield. The mounting block is made of plastic in the form of a rectangular box. To protect against accidental opening, the box is equipped with special latches. To open the module, you need to snap off the two protective brackets and lift the top plastic protection. Under the cover are all the main control relays and electrical fuses of the vehicle.
To quickly remove the fuse, special plastic pliers are located on the plastic protection cover. With their help, you can very easily get any element. You need to grab the top edge of the plastic case with pliers and carefully lift the element.
For the convenience of the user, on the top plastic cover there is a complete diagram, made in the form of a schematic image, which shows all the electrical fuses and relays indicating the current strength (A).

Additional items
Under the hood
Additional headlight wiper fuses (2A rating) protect the motor windings. They are located on the supply wires next to the gearmotors.
The starter activation relay 113.3747 or 90.3747-10 is located in the engine compartment on the right mudguard.
In the cabin
The windshield wiper relay (PC-514) is mounted under the panel on the left under the trim.
The ignition relay and the hazard warning and turn signal relays are installed on the front panel behind the instrument panel. The ignition relay (113.3747-10 or 90.3747-10) and the hazard warning and turn signal relays (23.3747 or 231.3747) have a bracket for direct mounting on the body.
The fog lamp fuse is located in the gear shift compartment, not far from the radio.
Starter, ignition, rear fog lamp relay
In order to carry out quick checks and repairs, the ignition system relay is installed under the front dashboard of the car, behind the hood release handle. It is located just below the central dashboard. The module is closed with a plastic plug, which must be opened slightly to test for functionality.
Starter, ignition, rear fog lamp relay
Next to the indicated relay, there is a similar one for the rear fog lights and the starter.
The main task of the relay when igniting is to reduce the applied load to the contacts. When the engine starts, the relay turns off some electrical circuits in the vehicle system. The system is used not only in injection, but also in carburetor engines.
In the event of a malfunction or malfunction in the ignition system, it is necessary to monitor the operation of the relay. For this purpose, open the box and carefully remove the desired element. It is attached using contacts to special grooves. The first thing to do is look at the oxidation of the contacts, if necessary, clean them with a soft cloth or treat them with a special liquid.
To check functionality, you need to use a regular multimeter. We connect to incoming connections and check the numbers. If there is no short circuit when current is applied, it means the element is not working. Replacement is carried out in a similar manner. It is necessary to use a standard element with the number of amperes indicated on the housing.
The device of wipers: what are they made of?
The device of the wipers is quite simple and consists of:
- trapezoid, transmitting movement from the motor;
- an electric motor driving the device;
- a pump that pumps washer into the device;
- tank for storing washer fluid;
- windshield wiper part with brushes at the end, mounted on a trapezoidal base.
Weak points of wipers
Weak points of wipers
In the entire device of wipers, the weakest point is the motor - its breakdown requires replacement. It is advisable to replace the relay along with it. The trapezoid can be restored in some cases. But what if the reason for the failure lies in the fuse or relay?
How to determine a faulty relay and fuse
The lack of movement of the wipers usually indicates a malfunction of the electric motor. Movement of the trapezoid while the glass remains dirty indicates damage to the pumping device or liquid tank.
Next, electronic faults are checked.
- When removing the instrument panel, you need to find the relay screwed to the body part.
- If the electrical elements do not work, the relay must be replaced - it cannot be repaired.
- You also need to check the fuse.
Front fog lamp relay
Front fog lights are not standard equipment on the model and are equipped depending on the configuration. The relay itself (if there are fog lights) is located in the engine compartment on the left mudguard.
Front fog lamp relay
Important! To access the relay, you must remove the battery! Without performing this manipulation, it will be difficult to remove and check its functionality.
Replacing a faulty element is very simple. You need to take a Phillips screwdriver (with a short handle), unscrew the bolt securing the relay to the car body, and check the element for malfunction. If it fails, we buy a new one and put everything in the reverse order.
Location of fuses on the diagram for VAZ 2110, 2111, 2112
Today we will look at the location of fuses in VAZ cars of the tenth family, namely models 2110, 21102, 21103, 2111, 2112. We will also show where the fuses and relays are located on the diagram and talk about the purpose of each of them and how to replace the fuses with your own hands. We will also touch on the most common problems with fuses among owners of these cars, diagnostic methods and replacement.
I would like to say that car electrical systems, in particular fuses and relays in the VAZ 2110, 21102, 21103, 2111, 2112, are quite reliable. The service life depends on operating conditions and timely diagnosis and replacement with high-quality components.
Let's figure out why fuses are needed in a car. First of all, they are responsible for the safety of the wiring and other systems of the machine. It is important to understand that each specific fuse is responsible only for its task and in the event of a short circuit or failure, a fire is practically excluded. A specific fuse blows and this does not cause a chain failure of other systems.
Depending on the problem of failure of any component or part of the car for which the electrician is responsible, you need to understand whether the car can be operated with this malfunction or not. The traffic rules contain a list of faults that you cannot operate a car with. If you discover, for example, that the headlights have failed or the wipers are not working at all, you should immediately correct the problem. Well, you can drive a car with non-working power windows. By the way, if someone suddenly needs a high-quality website for business, then these guys make good websites WebFormata.ru
