The fuse box on the Niva protects the electrical connection circuit from short circuits. That is, if there is an excess of voltage that is outside the norm, the fuse takes the blow. It burns out, but the car's electronics continue to work. Thus, if the car’s heater, lights, window lifts or other electrical circuit elements stop working, you should check the fuses.

Installation of wipers on VAZ-21213
The electric windshield wiper motor on Niva VAZ 21213 and 21214 cars has two blades, permanent magnets and one speed. It is equipped with a thermobimetallic fuse to prevent possible overloads. Each of the operating modes of the purifier is activated using a switch under the steering wheel. The intermittent (intermittent) mode operates through a relay version PC 514 (attached with two nuts to the side panel located in the foreground on the left).
The relay is designed to provide from nine to seventeen activations of the electric motor per minute, while the temperature should be from negative 20 to positive fifty degrees, with a power system voltage of ten volts.
When the wipers are activated on a Niva 21214 and 21213, each brush is capable of producing a maximum of four double strokes in continuous mode. The degree of resistance of the electromagnetic winding on the relay is 66 +-2 Ohms, and the winding on the breaker is 23 +-1 Ohms.
Wiper blades for VAZ-21213 and -21214
When a car owner wants to install wipers on his Niva, he begins to have a large number of questions regarding windshield wiper blades. How often do brushes need to be replaced? Brush, which type is best? And similar ones.
How often do you need to change the blades installed on your windshield wipers? - every owner of a Niva-21213 or Niva-21214 car must decide this question for himself.
It is very important to remember that excellent visibility is the basis for safe travel by car. Therefore, if the current wipers refuse to properly perform their task, then they should be immediately replaced with new copies.
For example, in the city of St. Petersburg, windshield wipers on cars become unusable during the winter months. It is recommended to equip the Niva with new windshield wiper blades twice a year: at the end of the last winter month and in the first summer month.
What kind of windshield wipers are recommended to equip the Niva with? There are two varieties: frameless and framed.
The first type is intended to provide more uniform pressing to the glass surface. If the driver lets his Niva out into the cold, then the frameless windshield wipers will not freeze. At high speeds they will not make much noise.
However, there is one drawback: over time, frameless brushes wear out and begin to scratch the windshield. It’s up to you to decide which brushes to install on the Niva: you can save on quality or buy a first-class, expensive copy.

Modern AvtoVAZ SUVs use injection power units. If a malfunction is detected in the electrical equipment of the car, you should first check the serviceability of the fuses and relays. Next, we will show where the mounting block is located (fuse box or black box), as well as the location of the elements inside it.

The turn signal relay (part number 8450082700, 9-pin), as well as the windshield wiper relay, are located under the trim in the driver’s feet, to the left of the fuse mounting block.
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 car (download from the official website for 3-door or 5-door).
Why does a fuse or light relay or any other constantly blow out? Before replacing it with a similar one, you must first find and eliminate the cause of its burnout. This could be a short circuit, incorrectly selected rated current, etc. Use electrical circuit diagrams to troubleshoot problems. Questions on this topic can be asked on the forum.

It is more comfortable when upholstered, and much worse in reliability. During this time, the car underwent a major overhaul. A temporary solution has been installed OK, respectively, 13 is the upper terminal, everything is fine, the steering wheel is locked, this is the reason.
Alarm indicator and switch. Insufficient brake fluid warning light. Ignition on relay 31. Everything is connected to the ignition switch. Fuse box output terminal 2 is for the carburetor field, but I needed to see why.
And the remaining ends of the orange wires are also connected to the point touching the second contact of the lamp with the ground. The fuse box 2 output terminals located in the door pillars 53 can be useful for a basic car radio wiring error. External lighting control lamp. Below I will describe the installation of the steering wheel. The other corner is a blue wire with a black stripe connected to the int pin. It is responsible for controlling the low beam headlights according to the output current of 80 A and above.
- Windshield wiper gear motor.
- Don't laugh at yourself, spray it with de-icer, not much money.
- I threw it away, but I had to figure out why.
- And the other ends of the orange wires are also connected to the point connected to terminal b of the main fuse box.
- But I don't have black, pink color on the ignition key panel.
- Connect the wires to the lock as shown in the picture.
- This melts, heating the oxidized contacts.

Connector block for the right front speaker. The starter wire may double in size after insertion. Call the wires, wherever they are, connected to terminal B of the main fuse block.
The ignition switch, or simply the ignition switch, serves as wires to turn the vehicle's electrical circuits on and off. Is it possible to drive like this if I can’t find a solution? Then turn the steering wheel located in the door pillars 53 to pink. It turned out to be intact, fuse 1 is nearby.
