VAZ 2107 instrument lighting does not work

The control devices stopped working or they began to “confuse” the readings, the control lamps and lights do not light up - in this case the panel will have to be removed.

Preparing for work

Before starting work, you need to buy replacement light bulbs. You can choose standard ones with or without sockets, as well as LED ones. If it is necessary to replace the incandescent lighting elements responsible for the backlight, then you will need light bulbs of the AMN 12-3-1 (T3W) type. These are ordinary filament bulbs that are installed in the dashboard of VAZs from the factory. If it is necessary to replace indicator lights, then type A 12-1.2 elements are used. Are you choosing LED?

You don't need a lot of tools:

• flat screwdriver;
• Phillips screwdriver;
• pliers.

If you are going to disassemble the panel and repair it, you will additionally need:

• multimeter or probe;
• soldering iron from 40 Watt;
• solder and rosin;
• side cutters;
• small screwdrivers.

Removing the panel from the car

Using a slotted screwdriver, remove the plastic plug on which the heating sign is depicted. This plug is on the right, and under it there is a Phillips screw that needs to be unscrewed. (There are 2 screws under the plug, but only one needs to be unscrewed - the top one, which secures the right side of the dashboard).

Next to the hazard warning button, there is an odometer reset button, which is secured with a plastic nut. The nut must be unscrewed and removed with the washer located behind it. The button is recessed inside the panel.

The right side of the tidy is weakened at this stage, and it remains to perform several additional manipulations in order to completely dismantle the device. To do this, pull out the right side of the device, thereby freeing access to its rear part. Here you need to disconnect all the chips and wires to perform dismantling.

Initially, the power chips for the stove button are disconnected. Be sure to remember the location of the wires. It is recommended to take photos so as not to be confused when assembly is carried out. Next you need to disconnect the speedometer cable. It is secured with a special nut, which can be unscrewed by hand.

All chips connected to the dashboard are disconnected. It is almost impossible to confuse their locations, since they have different fastenings and differ in size.

The supply hose is removed from the economizer fitting. This cable is located on the left side of the device. After all the chips, cables and wires are disconnected from the device, you can dismantle it.

Determining what doesn't work

If the backlight of the VAZ 2107 dashboard does not light up, this may be due to the following factors:

Faulty incandescent lamps

This rarely happens, however, due to the fact that from the factory the lighting of the panel is realized through the use of incandescent lamps, their burnout periodically occurs. The problem can be fixed by replacing the lighting elements, or better yet, installing LEDs. To make a replacement, you will need to dismantle the instrument panel. This is not difficult to do, but it will take a lot of time to disassemble the shield. The panel contains lighting elements, which must be replaced in order to restore the functionality of the VAZ 2107 instrument panel lighting. Before replacing, you should first check the serviceability of each lamp. The design of the shield uses 4 main lighting elements, which are responsible for lighting, as well as additional ones that act as an indication. If you had to disassemble the panel, it is recommended to immediately change them to LED ones.

Brightness control

The malfunction may be hidden in the part that is responsible for adjusting the backlight intensity. Although this part fails extremely rarely, its malfunction cannot be ruled out, especially if it has been established that the incandescent lamps are in good working order and do not need to be replaced. The light brightness control is located directly on the right side of the steering wheel near the headlight range control. If diagnostics have shown that this particular part is the reason that the backlight does not light, then it should be replaced.

Circuit breakers

The search for the reason why there is no instrument lighting on the seven should begin directly with the fuses. These elements protect the circuit from voltage surges, and as soon as a large current flows in the circuit or a short circuit occurs, the fuse link blows. If such a malfunction occurs, replace the fuse and check the power circuit.

Absence or poor contact at the point where the chip connects to the power wire

The reason for the lack of contact may be that the chip is not tightly pressed to the terminal block of the instrument panel. Poor contact occurs when contacts become oxidized. You can fix such breakdowns yourself by cleaning the contacts from oxides.

In addition to the main faults, there are additional ones, for example, damage to the power cable. If you have a multimeter in your arsenal, then identifying such a malfunction will not be difficult. Even if you don’t have a multimeter, it’s not at all necessary to contact a car service to fix the problem; you can use a probe with a light bulb.

Dashboard lighting for VAZ 2107: what lamps are needed and how to replace them

In order to replace the lamps in the lighting fixtures of your car, it is not at all necessary to go to a service station and pay a highly qualified specialist. All operations can be done independently with minimal effort and money. Today we will talk about replacing light bulbs in the dashboard (DP) of a VAZ 2107 car.

Location of lamps on the instrument panel of the VAZ 2107

Before we start replacing the light bulbs, let’s see where they are located on the PCB board and what the VAZ 2107 is responsible for illuminating or indicating.

Layout of dashboard lamps on a VAZ 2107, where:

1. Fuel level.
2. Instrument lighting.
3. The direction indicators are on.
4. Engine control controller malfunction.
5. Exterior lighting is on.
6. Emergency oil pressure.
7. The parking (hand) brake is on.
8. High beam headlights are on.
9. Battery charge indicator lamp.

Removing the instrument panel and preparing for replacement

To change the lamps in the instrument panel, the latter will have to be removed. It cannot be said that the PP can be removed with one movement of the hand: the designers of the VAZ 2107 made dismantling a little more difficult than on other cars of the VAZ family. Nevertheless, dismantling the PP is quite feasible in a garage or even a parking lot. In this case, the operation does not require any special knowledge. The tools we will need are:

• small flat screwdriver or knife;
• crosshead screwdriver.

Tips for motorists

When the instruments and warning lights on the instrument panel stop working, the driver of any car, including the VAZ-2107, becomes uncomfortable in the cabin of his car, since he will not have enough information that the instrument panel provides, as when starting the engine , and while driving.

The first thing drivers usually do is check fuse F10 (10A) , located in the mounting block and the condition of its terminals. If the fuse has not blown, then the cause of the failure of the instrument panel will have to be looked for in it itself. Therefore, we remove the instrument panel and in the left corner we look for two double black wires that are attached to the car body. This is “ground”, we check whether there is good contact and whether the fastening nut is tightened.

At the same time, immediately see if the pads are completely recessed, and you can also disconnect them and check the condition of the contacts. It happens that during installation they were bent, but due to vibrations they move away from each other and the instrument panel stops working.

But the most common reason for instrument panel failure is that the pins are attached to the instrument panel circuit board using rivets, and this connection is not reliable. As a result, the contact is lost, and the instrument panel stops working completely or works periodically, then turns on and off. This is especially evident in winter, until the interior of the car warms up, the shield does not work, and when a certain positive temperature is reached, due to the expansion of the metal of the rivets, contact is restored.

To eliminate this reason, you will have to drill out the aluminum rivets that hold the switching board and get to the connectors of the pads. Considering that the connector blades are riveted with copper rivets and not soldered, this is why contact is lost, which can be restored using an ordinary soldering iron. Then this disease of the instrument panel of the VAZ-2107 car will disappear forever. When assembling, you can use self-tapping screws instead of drilled aluminum rivets.

Why doesn't it light up?

• First, remove the cover of the mounting block and make sure that the fuse is intact. The fuse markings are located on the inner surface of the cover. You should look for fuse F16 or F5, depending on the year of manufacture of your VAZ 2109.
• If the fuse is intact, be sure to check whether the contacts of the fuse you are looking for have not oxidized. It is not uncommon for shields to fail due to broken contact.
• Check if there is power to the dashboard. To do this, you will need a warning light and the ignition on. Disconnect connector X4 in the mounting block and check for voltage at pin 3. The disadvantage of the VAZ 2109 design is that when it rains, the mounting block immediately becomes wet. This causes oxidation of the contacts in the pads, which causes the electrics to stop working. Sometimes not only the contact is oxidized, but also the board of the Nine mounting block.

If none of the above actions yielded results, you will have to be disappointed. After all, now you need to remove the dashboard and check the condition of the wiring, contacts, and negative connections. Here it is better to trust a professional electrician or set aside a whole day to troubleshoot problems yourself. There is no need to rush here.

Dimensions and instrument lights do not light up

Guys, tell me where to look for the problem.

The situation is this: a VAZ 2103 car, the dashboard from 2107 installed mirrors with dimensions and turn signals. connected the whole thing. worked without problems. but today an opportunity happened:

I went to work in the morning, turned on the headlights and low beams, everything was fine for 25-30 minutes, and then suddenly the instrument lighting went off. scales and sensors work, there is no backlight, and the low beam light does not light up. The lights on the mirrors and the front lower right hand light also stopped lighting up. At the same time, the remaining dimensions are on and the low beam is on. When you turn on the high beam, it lights up and the light on the panel also lights up.

I suspect there is a short to ground somewhere. tell me where and what to look for.

There is also a problem with the heated rear window. connected according to the circuit through a relay, power is supplied to the glass heating, checked with a tester. but - in 20-25 minutes of driving, only thin strips thaw from fogging (the thickness of the heating threads themselves is slightly thicker).

thanks for the help

Fuse box VAZ-2107

The VAZ-2107 fuse box is located in the engine compartment, to the right of the engine (if you look in the direction of travel of the car). It contains the main fuses and relays. To check whether any of them have burned out, you need to open the hood and the plastic cover of the block, on which the names of the fuses and their nominal values ​​​​should be indicated.

R1 - relay for turning on the heated rear window . If the heating does not work, check this relay, as well as fuse F5, replace the burnt or faulty ones. If the relay and fuse are working, check the contacts for connecting the wires to the heating strips on the rear window (on the side closer to the side doors)

R2 - headlight high beam relay . Works in conjunction with fuses F12 and F13. If only one headlight does not shine on high beams, most likely the problem is in the lamp, which is time to be replaced or in fuse F12 or F13 (right/left headlight, respectively)

R3 - headlight low beam relay . Works in conjunction with fuses F16 and F17. If the low beam does not work in both headlights, it is most likely the problem with this relay. First of all, replace it with a working one. If it doesn’t help, both lamps could have burned out (this happens) or their fuses.

1 — connector for the relay for turning on the headlight cleaners and washers . If your car does not have these devices, then the presence of a relay is not necessary.

2 — connector for the horn relay . In the figure, a jumper is installed so that the sound signal works without this relay.

3 — connector for the cooling system fan motor relay . In the figure, a jumper is installed so that the fan operates without this relay. Be careful with this connector. Failure to contact the jumper in the absence of a relay can cause the fan to fail, and this can lead to overheating of the coolant and, accordingly, the engine. When the first signs of overheating appear (according to the temperature sensor and boiling of the liquid), turn off the engine as soon as possible.

4 — tweezers for replacing fuses 5 — spare fuses 6 — tweezers for replacing relays

Try to always have spare fuses of different ratings, so that if they blow out on the road, you don’t have to look for the nearest car shop.

General tuning aspects

By tuning the dashboard of a VAZ 2107, you can change not only the appearance, but also improve its performance (video author - Auto overhaul).

For night time, the electronic instrument panel on the VAZ 2107 can be equipped with good backlighting. You can get creative and use overlays on the instrument panel to improve the appearance of the dashboard. You can make new scales for VAZ 2107 instruments yourself or order them printed.

If you have finances for a VAZ 2107, it is better to entrust tuning to professionals who will do everything efficiently and quickly. You can do it yourself, just be patient and if something doesn’t work, you need to look for the reasons and fix it.

Emergency situations determined by the dashboard indicator

The VAZ 2107 instrument panel allows you to detect most malfunctions in vehicle systems without leaving the driver's seat.

• The low oil pressure light comes on. You should immediately turn off the engine, stop and check the oil level in the crankcase. If necessary, add oil and then start the engine. If the oil level is sufficient and the lamp is on, you cannot continue driving. The car needs to be towed to the repair site. Otherwise, the bearings (crankshaft bearings) will wear out or rotate and the engine will knock or jam, which will require expensive overhauls.
• The battery warning light comes on. In this situation, you can continue driving, but you should take into account that you won’t be able to travel far, especially at night, as the battery will quickly discharge. You need to start by checking the condition of the terminals. If they are oxidized, clean them. If the terminals are in order, it is necessary to check the functionality of the generator or voltage regulator relay (often the reason for the lack of charge lies precisely in the latter).
• If the brake fluid level warning light comes on, you should stop immediately. It is unacceptable to continue driving with faulty brakes. After stopping, it is necessary to add brake fluid and check the functionality of the brake system. If the brakes work, you can drive to the repair site yourself. Otherwise, you need to fix the breakdown on site or call a tow truck.

• If the coolant temperature gauge needle is in the red zone of the scale, you need to stop to let the engine cool down. When the temperature drops, you can check the condition of the pipes and the coolant level. If the level is normal, then you can try to go to a service station to find out the cause of the breakdown. Most often this is a malfunction of the thermostat or radiator fan. The VAZ 2107 panel is not equipped with an alarm or an additional lamp that lights up when the engine overheats. Therefore, inexperienced drivers often do not notice this problem, which can lead to antifreeze boiling away or even jamming the engine.

Instrument panel lighting

1. We disassemble and remove the instrument panel to get to the board with the lighting and alarm lamps. You can change them without completely removing it, but you need to act carefully so as not to break the wiring
2. Turn the light bulb socket that needs to be changed a quarter turn and remove it.

3. The lamp is pulled out in the same way as the socket - by turning it 90 degrees.

Video instructions for replacing instrument panel light bulbs on a “classic”:

In some modifications of the VAZ 2107, baseless lamps can be used. Therefore, it is better to check which ones you have installed, buy them, and only then disassemble the dashboard. Such a light bulb is simply pulled out of the socket without rotation.

You can buy it on the market together with cartridges for installation in a panel. In this case, it is enough to remove it from the “tidy” board and install a new light bulb assembly with a socket - simple and reliable, but they are more expensive.

Instrument lighting of VAZ 2107 does not work

Everyone understands that the illumination of our devices (speedometer, tachometer, etc. leaves much to be desired. In reality, it works very poorly. I would even say disgusting. In the dark, it is impossible to look at the instruments without tears. There are several cardinal solutions here, right up to changing the composition of the devices of the VAZ 2105 to the “Volgov” one, but this is not an economical option and will not suit many people.That’s why we will now fix this perfectly and on a budget.

So we buy these Blue LEDs

Pay attention to the LED lens made in the form of a funnel, such a lens scatters the light of the LED and it is advisable to take specifically such diodes. Why blue? There is a very exciting effect with blue LEDs. It seems as if the arrow and scales of the devices are shining. like foreign cars. There is no such effect with snow-white LEDs. I don’t know about the other colors. How many diodes will be needed? I have a modified composition of devices, for small devices of the VAZ 2104 I used one diode each, and for large ones (speedometer and tachometer) 4 diodes and one diode lamp each. A diode lamp looks like this

Popular faults

If we talk about the dashboard of VAZ 2109 cars, then they are characterized by certain problems. We will tell you about them, and also tell you how to act correctly in a given situation.

The instrument panel of the VAZ 2109 is not so complicated that you cannot figure it out on your own. But in the absence of experience, it is better to entrust the repair to specialists, or to enlist the support of a partner who understands this matter.
