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).

Problems with the sound signal device
The signaling device mechanism is not protected from moisture getting inside. Why contacts and membrane oxidize. If the external contacts of the wire connecting to the signaling device are oxidized, there is no need to remove it. It is enough to remove the connector and clean the contacts. If this procedure does not help, you will have to remove the alarm device by unscrewing the screws to check the condition of the membrane. Sometimes it is enough to wash the membrane with kerosene or clean it with fine sandpaper. But if a crack or other defect is found on the membrane, then you will have to buy a new signaling device and install it.
Please note that to eliminate the oxidation process inside the signal mechanism, universal lubricant VD-40 helps.
The strength and timbre of the sound of the signaling device is regulated by rotating the adjusting screw on the front wall of its body.

Recommendations for care and maintenance
- Buy original fuses. Domestic or foreign, it doesn’t matter;
- Install strictly in accordance with amperage ratings. Unacceptable with lower or higher current strength. In the first case, this will lead to damage to the module, in the second - to breakdown of the unit, which is attached to the fuse;
- Carefully check the quality of fixation of terminals and limit switches on the board. If loose, tighten and press with pliers. A spark can cause a fire and melting occurs;
- If moisture gets in or condensation forms inside the mounting block, remove the cover, dry it, and if necessary, blow it with a stream of compressed air.
Carry out preventive and diagnostic work in the fuse box with the battery terminals removed in order to prevent a short circuit in the circuit.
The average service life of fuses is 40 – 60 thousand km. The service life of foreign analogues is 10–15% longer. Before replacing, read the instructions and get advice from service station specialists.
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.
Other possible causes of washer malfunction
After the car owner determines which fuse is responsible for the VAZ 2114 windshield washer, it is necessary to check its functionality. If other circuits protected by the fuse operate without changes, this means that the fuse element has not failed. There are a number of other reasons why your windshield washer may not work.
Electrical damage
- The connection between the contact pads of the fuse and the mounting block is broken. A malfunction may occur as a result of violation of the rules for installing a fusible element or the appearance of oxidation. To eliminate the malfunction, it is necessary to restore contact.
- The mounting block installed in the engine compartment has failed. You should replace the unit with a known working one or resolder the contact tracks.
- Broken steering column switch. A malfunction results in the inability to close the circuit and turn on the electric motor. If a breakdown is detected, it is necessary to replace the steering column switch with a known working part.
- Broken wiring. Damage to the wires going to the electric motor in some cases causes the washer to not work. To identify the malfunction, you will need to check the integrity of the wires using a multimeter. The damaged element should be replaced with a new one.
- Relay K3 does not work. The malfunction may be due to a poor connection between the relay contact pads and the fuse box or a broken relay. Parts are replaced by known workers. If necessary, contact pads are cleaned of oxidation.
Mechanical breakdowns
Incorrect operation of the washer may be due to mechanical problems. The most common ones that fail are:
- Pump. The use of low quality fluid leads to rapid wear of pump parts. You can check the performance of the VAZ 2114 windshield washer motor yourself, without the use of specialized equipment. To carry out diagnostics, the pump is removed from the car and connected directly to the battery. If a breakdown is detected, the part should be replaced with a new one.
- Hose. Under the influence of negative environmental factors, microcracks appear on the outer surface of the washer hose. The size of the hole in the nozzle is much smaller than the diameter of the hose. As a result, pressure builds up in the hose while the washer is operating. Together with microcracks, this leads to its rupture. A sign of a malfunction is the normal operation of the pump and the lack of water supply from the nozzles with a simultaneous decrease in the liquid level in the tank. To eliminate the damage, you need to replace the hose with a new one.
- Nozzle. A small hole in the sprayer is provided to supply liquid under pressure to the windshield. Using a low-quality washer leads to clogged nozzles. Troubleshooting involves replacing parts or cleaning them. To ensure proper spraying of the liquid after repairing the injectors, they will need to be adjusted.

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.
