Author: Ivan Baranov

If any equipment on a car fails, the first thing you need to do is check whether the fuse is intact. This is not difficult to do and even a novice motorist can do it, and there is no point in going to a service station for this. A simple replacement can cost you a pretty penny. To do this, just find the VAZ 2121 Niva fuse box, which the designers placed in a very accessible place.

Electrical fuses on cars are changed if they blow out, without fail observing their rating. But other situations also happen on a VAZ 2121 Niva. For example, many motorists complain that sometimes electrical fuses simply fall out of the block. That is why it is recommended to replace the old unit with a new one, in which the safety elements hold up much better.

Where is the DTOZH of the VAZ 2123 engine?

The coolant temperature sensor is an electrical resistor with a built-in thermometer. The device is called a thermistor. The principle of operation is simple: when the temperature changes, the resistance changes, which affects the executive part of the system. To measure the thermistor, use a multimeter set to resistance.

Relay and fuse diagram for VAZ Niva

Car owners are well aware that the VAZ 21214, 21213 (Niva) fuse box is a critical detail that requires detailed study. Knowledge of the electrical circuit allows you to avoid many problems and carry out timely diagnosis of breakdowns. Since the family has existed for many decades, it has managed to go through a number of radical changes - the transition from carburetor to injection engines, for example. This did not entail a radical change in the location and content of the mounting blocks, of which there are two in the cabin and one under the hood.

VAZ Niva fuse diagram for injector

The Niva with fuel injection has today almost completely replaced the carburetor models of the family. With the transition to a new injection system, the manufacturer tried to minimize the inconvenience for the car owner and not radically change the location of the mounting blocks, as well as their filling with protective elements. Traditionally, there are two of them in the cabin. Another one, in the back, is responsible for controlling the engine.

Fuse box VAZ 21214 Niva with description

In the interior of the VAZ 21214 Niva with fuel injection there are two fuse blocks. One of them is located in the traditional place - to the left of the driver's hand and the dashboard. But the second one is located below, near the central tunnel, on the passenger side. In the updated models, it was in this block that the fuses responsible for various types of headlights were placed.
Both blocks are connected to each other. The total number of fuses in the upper one is ten, while at the bottom there are six, including reserve ones.

Removal and replacement process

In order to replace a blown electrical fuse, special knowledge and skills are not required. Everything is very simple.

Required Tools

To work, we will need the most common tools that any driver always has at hand, namely:

A set of keys that every car enthusiast should have

Stages

• Before starting replacement work, you need to disconnect the negative battery cable.
• Next, using a screwdriver, unscrew the screws that secure the casing and remove it.
• We look at the diagram to see where the blown fuse is located.
• We find it in the block and remove it.
• We take the same one at face value and install it in place of the extracted one.
• Attention! On the back of the block there is an electric fan fuse with a rating of 30 A, its body is painted green. The other elements are rated 15A and are blue.
• If we do not plan to change the block, then the work is finished and all we have to do is install the casing in place and secure it with screws.
• But if you decide to put the system with fuses in order and replace the old block with a new one, then we need to use an 8-mm socket to unscrew a couple of nuts that secure the block.
• Now we remove the block itself.
• Disconnect the block with wires.
• We change the block.
• We install fuses in it.
• We secure it with nuts.
• We return the casing to its place and tighten the screws.
• This completes the work with electrical fuses on the VAZ 2121 Niva.

Attention! If the fuse blows again, then it is necessary to look at the entire circuit, and specifically at the consumer for which this fuse element is responsible.

Never use homemade jumpers or a fuse of a different rating instead of a blown one.

This video uses the example of a VAZ six to show some reasons for replacing the block. As you can see, during operation the body was deformed and melting was noticeable.

Like the video, everything is very simple in terms of time; such work will take no more than half an hour, instead of two or three hours of standing at a service station and spending extra money.

(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. Also, the turn signal relay can be located behind the instrument cluster, or under the center console closer to the left side.

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.

Location

All fuses are located in a special block, which is located under the dashboard on the driver's side. In order to gain access to them, you need to remove the cover, which is secured with two screws, removing which you can see 8 electromagnetic relays and 20 protective elements. The main task of the relay is to relieve the switch contact of the device, since they consume current for which the switches are not designed.

Before installing a new element, it is necessary to understand the reason why it failed and eliminate it, otherwise they will constantly burn out. This can be done using a special tester, as well as an electrical circuit diagram. If you do not have the necessary device or do not understand the circuit, then it is better to contact a specialist.

Let's take a closer look at what each device is responsible for:

The Niva Chevrolet mounting block also has relays that are responsible for:

• K1 is usually not used and a special jumper is placed in its place
• K2 is responsible for turning on the wipers
• K3 thanks to it the emergency lights and turn signals are turned on
• K4 is responsible for turning on the low beam
• K5 provides power to the low light
• K6 relay for heated rear window, ventilation and heating system, washer
• K7 heated rear window
• K8 is a backup

There is also a separate block that controls the operation of the engine and has the following circuit:

Every driver should have a printed Chevrolet Niva fuse diagram in his car, this will make it possible to reduce the time of searching for the right device.

Lada 4×4 3D › Logbook › Extras. Niva starter relay

Hello friends! I wrote about my problem with starting the car earlier, the essence is simple: you turn the key, and in response there are only clicks. I didn’t know what it was, the car had this problem since it was purchased in November 2015. Since then, there have been no hypotheses, no matter what has not changed (explosive wires, starter retractor, switch), in addition, all the places where the minus is attached to the body have been cleaned. Nothing helped. We thought and wondered, consulted for a long time - what to do? I asked a question here, they gave me different advice, and so my friend and I decided to install an additional relay on the starter. Maybe it will help! And let me tell you, it helped! To solve the problem, we bought: a 4-pin 30A relay, “mothers, fathers”, 1.5 wire (taken with a reserve), heat shrink. We prepared and assembled everything according to the diagram, all that remains is installation.
