The first thing you need to figure out is why the instrument panel on the VAZ 2114 does not work. If the backlight goes out, there may be several reasons for this:

  • The incandescent lamps burned out, the LED lighting groups stopped working;
  • The connectors have oxidized;
  • The electrical wiring is faulty, there are defects in the circuit;
  • The fuse box has stopped working;
  • Damage appeared on the common contact board;
  • The dimensions system is damaged;
  • There is no minus on the body (weight).

Let's look at the problem: the backlight of the VAZ 2114 instrument panel does not light up

An element such as the dashboard is very important for the driver - because it is thanks to it that he can control the most important parameters of his car while driving. And that is why a serviceable instrument panel ensures not only comfortable driving, but also the safety of the motorist and his passengers.

For a clearer perception of instrument readings on the panel, especially at night, it has a built-in backlight. True, situations often occur when the backlight of the VAZ 2114 fails. We’ll talk about why this happens and how to restore its functionality with your own hands below.

Causes of malfunctions

There are a number of reasons why the instrument lighting of the VAZ 2114 may stop working correctly.

The most common of them are:

  • light bulbs have burned out or diodes have failed (with LED backlighting);
  • contacts and connectors have oxidized;
  • fuses are blown;
  • damage has occurred in the wiring itself;
  • the integrity of the common contact board has been compromised;
  • Lost contact with the “mass”.

Removing the dashboard

To replace the light bulbs in the dashboard of the VAZ 2114, it will first have to be dismantled. Without this action, you will not be able to access the problematic device.

Therefore, now we’ll figure out how to disassemble the instrument panel on a VAZ 2114:

  • Unscrew the three screws, remove the trim and the protrusion from below. It comes out of your car's body bracket;
  • Now remove five more screws located on the right console trim;
  • Remove the screen; Disconnect the negative terminal from the battery;
  • Disconnect the wiring harness connector from the cigarette lighter;
  • Remove the handle from the lever;
  • The fasteners for the electric fan of the heating system, that is, the stove, also have to be removed;
  • Unscrew the steering wheel block bracket fixing bolts;
  • Remove LEDs, lamp sockets and decorative inserts on the panel;
  • Unscrew the hydraulic corrector illumination lamp. For this you will need a key for 21;
  • Now all that remains is to remove the screws at the top and bottom.

Thus, we figured out how to remove the dashboard on your VAZ 2114. Be sure to cover the electrical circuit with something after the measures have been taken to prevent moisture, dust and all kinds of contaminants from getting there.

Proceed to replace the lamps that turned out to be faulty. At the same time, many are interested in how many light bulbs are in the dashboard of the VAZ 2114. There are 13 of them, but only 8 can be replaced. Do not forget to clean the contacts if there are traces of oxidation on them. In some cases, it is not the lamp itself that has to be replaced, but the socket for it.

Replacing the panel backlight

In order to improve the state of light radiation and reduce the wide color variety, you need to place new LEDs in the panel that meet the wishes of the car owner and create optimal conditions for improving the lighting of the device. You can read the designation of the icons on the instrument panel of the VAZ 2114 in our other article.

Before changing the instrument panel lighting on a VAZ 2114, you need to buy a new set of LED lamps and calculate the correct number of diodes for each sensor, for example, for the brake sensor - you need 3 pieces. etc.

After removing the block, the resistor and light bulbs are attached to the VAZ 2114 dashboard in pre-designated places, sockets, according to the strict polarity of the location of the LED heads, which are carefully ground off. After completing the work, power is supplied and the functionality and quality of the backlight is checked.

Next, complete assembly is carried out, all the wiring from the diodes is brought out to the board and carefully attached so that they do not interfere with the installation of the panel.

It is important to carefully monitor the location of the instrument needles so that the drives do not bend or become deformed. The entire structure, lighting of the VAZ 2114 dashboard is fixed with screws. The power supply of the LEDs is connected to the lamp one, the arrows are put on, and the zero indicator is set.

Now you can monitor all sensors and instruments using the on-board computer. If all control identifiers are normal, the panel returns safely to its normal place.

Step-by-step instructions for disassembly

  1. The first step is to remove the left screen. To do this, you need to unscrew 3 screws, as shown in the photo. Once the fasteners are removed, the left dash screen can be removed.

Now the console can be completely removed if replacement is planned. When performing other repair work, it is recommended to navigate by access to the parts of interest. For example, to access the heater stove, it is enough to remove only the lower part of the dashboard.

Causes of malfunctioning dashboard lighting

The instrument panel on the VAZ 2114 is a whole complex of interacting sensors and equipment. Therefore, it is quite difficult to determine exactly why it does not burn. However, the problem in most cases occurs due to one or more of the following malfunctions:

  1. The filaments in the light bulbs burned out or the LED elements were damaged.
  2. A deposit of oxides has formed at the contact points of electrical connections.
  3. Fuses have blown.
  4. Electrical wiring is damaged.
  5. The contact board has failed.
  6. The “ground” on the body has disappeared (negative charge from the battery).

For those who are familiar with the basics of automotive electrics of the VAZ 2114, it will not be difficult to independently find the cause of the breakdown. To do this, you will need to carry out a series of dismantling works and check the availability of power supply in individual components, armed with a tester or voltmeter.

The backlight on the VAZ 2114 dashboard disappeared - why and how to fix it

The dashboard is an important source of information for the driver about the condition of the car. Without it, safe operation of the machine is simply impossible, so the panel must be visible around the clock. At night, the panel is illuminated to help you see it. But it, like any other VAZ 2114 system, can fail. Fortunately, it is quite possible to repair it yourself.

Reasons for turning off the dashboard on the VAZ 2114

Turning off the dashboard lights does not bode well for either the driver or the car. Because this malfunction is usually followed by others. Therefore, the backlight should be repaired immediately.

You should also understand that if the lights on the dashboard go out, then the problem must be looked for somewhere in the on-board electrical system. This means you can’t do without a multimeter, a soldering iron and electrical tape. Here are the main reasons for turning off the backlight:

  • fuse burned out;
  • the light bulbs have burned out (or LEDs - in later VAZ 2114 models the panel is illuminated by them);
  • the wiring in the on-board electrical network is damaged;
  • The common contact board of the instrument panel burned out.

Let's consider these points in more detail.

Burnt fuse

80% of cases when the backlight turns off is due to a blown fuse. It is located in a safety block installed under the steering column of the car. Usually the fuse indicated in the documentation as F10 is lit.

It is he who is responsible for the dashboard lighting, side lights and license plate lighting. On early VAZ 2114 models, fuse F10 was brown or red.

On later cars they started putting green ones. It is not difficult to understand that the fuse has blown. It's enough just to inspect it. The housing of a blown fuse may be slightly blackened or melted, and the conductor inside the housing may be severed. The faulty fuse is replaced with a new one. Typically this solves the problem.

Burnt out light bulbs

Dashboard lights operate under less than ideal conditions. They are regularly exposed to shaking, power surges in the car's electrical network and temperature changes. All this significantly reduces their service life. Especially if these are not LEDs, but ordinary incandescent lamps, which were equipped with the first VAZ 2114 models. There are a total of 19 lamps (but this number also varies depending on the year of manufacture of the car, and the number of lamps should be specified in the technical documentation for the car).

Another reason for light bulbs to burn out is their improper installation. This is most often observed on early VAZ 2114 models, where drivers decide to independently replace obsolete incandescent lamps with new LEDs, making some changes to the electrical circuit. Without proper qualifications, this operation is not so easy to perform. Here's what the sequence for replacing light bulbs looks like.

    The steering column is lowered to the bottom position until it stops. Above it is the dashboard cover with four mounting screws. They are unscrewed with a Phillips screwdriver.

Wiring damage

Problems with electrical wiring are the worst case. To figure this out on your own, the driver needs to have serious knowledge of electrical engineering. In particular, he must be able to read automotive electrical circuits well. Not all car enthusiasts can boast of such skills. It is for this reason that it is better to entrust the search for a damaged section of on-board electrical wiring to a qualified auto electrician.

His actions boil down to the following: he determines the key sections of the circuit and sequentially “rings” them using a multimeter until he finds a broken section of the wiring. Completing this work may take several minutes or several hours - it all depends on where exactly the circuit break occurred.

Panel contact board problems

If all of the above measures do not lead to anything, the last option remains: damage to the contact board in the dashboard. This part is a combination of several microcircuits. It is not possible to repair it in a garage without special diagnostic equipment. So the car owner has only one option - to replace the entire board. You can purchase it at any auto parts store. It costs about 400 rubles. Let us list the stages of its replacement.

  1. First, all the steps mentioned above in the paragraph on replacing light bulbs are performed.
  2. But instead of unscrewing the bulbs, you should unscrew the four bolts at the corners of the rear wall of the dashboard.
  3. The back wall is carefully removed along with the board, which is attached to the wall with plastic latches.

So, the owner of a VAZ 2114 can solve most problems with the dashboard lighting on his own. All that is required is the ability to use a screwdriver. The exception is the case of damaged wiring. It is strongly recommended that you contact an electrician to identify the damaged area. This will save a lot of time and nerves, which, as we know, are not restored.

Solutions

First of all, you need to check the backlight bulb; if it does not work, it needs to be replaced. Also, the reason that the instrument panel does not light up in the VAZ 2114 may be a violation of the integrity of the wiring. She should be called. A damaged fuse and electrical circuit, as a rule, cannot be repaired - they simply need to be replaced. Let's look at quick ways to solve these problems.

One or more light bulbs do not light up

One of the most common reasons why the instrument panel lighting on a VAZ 2114 stopped working is burnt out light bulbs. The electrical circuit in this model is designed in such a way that if one light source fails, all of them stop working. To determine exactly what is broken, you will need to ring the entire system using a tester. Another reason for the lack of lighting may be the independent installation of LEDs instead of standard incandescent lamps. In this case, an error is often made in the distribution of power or the electrical parameters of the led elements are calculated incorrectly.

Main conclusions

When the dashboard on a VAZ 2114 does not light up, it is important to correctly remove the unit, conduct a detailed inspection of the instruments, examine them under a magnifying glass, check the condition of the fuse, and then check the correct power supply to the panel. Then ring the backlight lamp tester and if the fuses or LED lamps are faulty, replace the faulty unit according to the sample and technical specifications of the equipment.

Before replacing the light bulbs in the instrument panel of the VAZ 2114, it is necessary to remove the battery terminals, disassemble the decorative trim of the instrument panel and remove the shield. After troubleshooting work has been completed, it is necessary to check the contacts of the devices. To do this, you need to press the reset button and hold it for a few seconds, turning on the ignition before this action. When all the indicator arrows have checked from zero to maximum values, the VAZ 2114 instrument panel is assembled correctly and is ready for installation in its original place.

Every car owner must follow safety rules when working with vehicle mechanisms and correctly adjust the operation of all units to avoid breakage and damage to parts. Conduct equipment diagnostics in a timely manner, eliminating faulty elements accompanied by qualified support or directly at technical service points.

Troubleshooting steps

To diagnose and repair the backlight system for the instrument panel on a VAZ 2114, you will need a pair of wrenches, sizes 8 and 21, and a set of screwdrivers. The general procedure for dismantling and adjustment work boils down to the following steps:

  1. Remove the trim by first unscrewing the three fastening screws and removing the protrusion from the body part bracket.
  2. Remove the five mounting screws from the right side of the console and remove the screen.
  3. Disconnect the terminal with the battery suitable for the negative power source, as well as the block with the bundle of wires from the cigarette lighter system.
  4. The handle of the lever mechanism is removed.
  5. The stove ventilation system clamp is dismantled.
  6. The screws securing the steering column brackets are removed.
  7. The sockets are unscrewed, the light guide and the decorative panel insert are removed.
  8. The light bulb for illuminating the hydraulic corrector is removed using a 21 key.
  9. Finally, the screws that secure the top and bottom of the instrument panel itself are unscrewed so that it can be removed.

Once the instrument panel is removed, you can begin to find the reason why the backlight is not on. First of all, it is customary to check the lamps on the VAZ 2114. If they are working properly or after replacing the damaged unit the system still does not work, you should clean all contacts from the oxide film. To speed up the process, it is better to use special mixtures such as VD-40.

What's next

After all devices are disconnected from the car, you need to remove the handles from the heater switches.
This can be difficult to do, because they are fixed quite firmly. To install the handles, special latches are used, which are installed inside. There is a small protrusion on each handle that will help us remove them. You just need to get into this hole with the tip of a minus screwdriver, then pick up the latch and lift it up. The further procedure is as follows:

  • The handle of the stove motor is removed. It is enough just to slightly pull it towards you;
  • The torpedo is fastened to the instrument block using several self-tapping screws. They are removed using a “plus” screwdriver;
  • Next, you need to remove the plug. It is fixed with a single self-tapping screw that needs to be removed;
  • The cover is held in place by two fasteners. And again the screwdriver comes to our aid;
  • Let's move on to the cables that are connected to the switches. They must be carefully removed, having previously marked each of them;
  • Next, remove the steering mount bracket bolts;
  • remove the fasteners from the bottom of the bracket. The key to 8 will help us here;
  • remove the light guide;
  • Next in line is the heating system control unit. Unscrew the fasteners and remove the cartridges;
  • in front of us is a decorative insert. We also don’t need it, so we temporarily get rid of it;
  • remove the hydraulic corrector;
  • The last step is to dismantle the upper and lower fasteners.
