Why does the VAZ 2114 instrument panel not work? Mass problem of our auto industry

The search for possible reasons why the VAZ 2114 instrument panel does not work periodically worries one or the other owner of cars of this model. Of course, if you do not see a single parameter on the dashboard, you can only go, as they say, by touch. True, there are certain specialists who still managed to somehow crawl to the base without any evidence, but somehow I don’t want to follow their example.

And is it necessary to create additional troubles and the risk of an accident on the road? So most of those with whom this incident happened still get to work (or where they were going there) by public transport in order to return to solving the problem in the evening on their own or with the help of a familiar auto repairman.

Why does the VAZ 2114 instrument panel not work? Offhand, several reasons can be named at once. However, they may not be an exhaustive list, as individual characteristics of the car may appear. We will try to talk about this and many other, no less interesting, in our today's article.

The most common breakdown

Before digging into the interior of the car, check how securely the ground wire leading to the front panel is fixed. A restless passenger in front often simply pulls him out of his seat with his feet. So that the situation does not repeat itself, after fixing it is worth isolating the wire from reach.
The situation is a little more complicated

Its symptoms are very characteristic:

• Pointers don't work all: speedometer, tachometer, odometer, fuel level recorder, ;
• The rest of the set of equipment - optics, radio, even the backlight of the panel turn on normally and do not act up;
• The ignition works in a mode, the car does not refuse to start;
• Almost 100% F3 fuse blown. It is located in the mounting block, it will be necessary to change it. But first you need to find out why he covered himself, otherwise the new one delivered will suffer the same fate. In most cases, a short circuit is to blame for the burnout. On well-used VAZ-2114 after each wash. Instead of carrying a spare with you, you need to figure out where the moisture comes from.

If the fuse is intact, this is not a reason to immediately leave it alone. It will not be superfluous to remove it and check the contacts: with a live fuse, but oxidized terminals, the circuit will be interrupted, and the tidy will stop showing any signs of life.

Next weak link: It is the ignition relay. It is located to the left of the steering column, fixed on a hairpin, so to speak, upside down. You need to remove it and try to directly make contact with the wires. With obvious signs of revival on the dashboard, it immediately becomes clear that the time has come to change the relay.

Hard case

So far, situations have been dealt with when the torpedo still showed some signs of life. If non-working power windows, turn signals, windshield wipers are added to the devices, it is no longer a matter of relays and fuses.

There may be 2 options:

• Burnt contacts on the ignition switch. In principle, after installing the relay (still on the VAZ-2109 version), such a problem occurs infrequently. However, the possibility remains. The lock is removed, the contacts are checked, if necessary, they are cleaned;
• Mounting block. Tracks may be burned out on its board. Saved only by replacing with a new one. However, it costs by no means cosmic, and the installation is available in independent execution.

Special situations

General signs do not always indicate specific breakdowns. There may be exceptions.

If some devices refuse to work, it is quite possible that this is their personal problem. You have to parse a specific pointer. It could crack a gear that should be replaced.

Also, why does the VAZ 2114 instrument panel not work? If the fuel gauge and tachometer are capricious (they function, then they don’t react at all), the contacts and the mounting block are normal - you need to arrange a small check.

Reset is pressed and held, the ignition is turned on in parallel. The raised arrows indicate the need for further searches. Lifeless - that microcracks appeared in the shield itself. We'll have to remove it and examine under a magnifying glass all the rations and tracks. In principle, these are all the main options. If the ringing of all the listed components and parts did not lead to the revival of the instrument panel, your case is individual, and you will have to determine the situation in a company with an experienced auto mechanic.
