Replacing a VAZ 2107 torpedo with your own hands: instructions for replacing the panel and individual instruments

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.

What are the reasons for the dashboard backlight not working on the VAZ 2107?

The situation when, when the instrument panel backlight is turned on, it does not work, is definitely unpleasant. If this happens, then it is necessary to fix the breakdown as quickly as possible, since operating a car at night is not at all uncommon, but a common occurrence. If the backlight of the VAZ 2107 dashboard does not light up, this may be due to the following factors:

1. 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 perform its tuning.

These are the main reasons for the malfunction of the instrument panel lighting on the VAZ 2107. 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.

What lamps to install in the instrument panel for lighting

One of the common causes of malfunction is burnout of incandescent lamps. To restore the functionality of the tidy lighting, you will need to disassemble it and replace the lamps. Due to the fact that the illumination of the instrument panel of VAZs is realized through the use of conventional incandescent lamps, many car owners seek to modernize this design. Let's find out which lamps to install in the tidy to restore the lighting functionality.

• 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.

If there is a problem with the incandescent lamps of the VAZ 2107 tidy burning out, then it makes no sense to buy the same elements, since their main advantage is their low price. However, they have a short service life, and their glow quality is poor. That is why it is recommended to immediately install LED lamps in the backlight of the seven’s instrument panel.

This is interesting! If you change the incandescent lamp indicating the battery charge, you will need to solder a resistor of the appropriate value to the LED. If you simply replace the halogen charge indicator with an LED lighting element, the battery will not charge correctly.

As can be seen from the material, it is not at all difficult to troubleshoot the backlight of the instrument panel of the seven. To do this, it is necessary to properly approach the identification of the causes of the breakdown and carry out troubleshooting. If there is a desire, the tidy can be tuned not only by screwing in LED lamps instead of halogens, but also by adding LED strips to the dashboard, which will improve the quality of lighting of the dashboard and add individuality.

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.

How to replace light bulbs in the dashboard of a VAZ-2107

With warming up the interior or tapping the panel with your fist. Usually, this problem disappears and everything gradually turns on, but the consequence of this is a discharged battery, loss of time due to warming up the car and lost nerves.

The reason for this disgrace is poor contact of the terminals with the instrument board due to the fact that they are not connected through soldering, as on all machines, but through copper rivets.

Over time, oxides form on the metal, and at low temperatures frost also forms, the metal is deformed and the current cannot break through this barrier. Therefore, many drivers solder these connections with a regular home soldering iron, which we will do as well.

First, we need to remove the instrument panel from the car panel. To do this, unscrew the mounting bolt, pull out the radio if it is installed there instead of the air ducts, and disconnect the heater motor activation key.

Use a screwdriver to pry up the lower right edge of the panel and press it out of its seat.

Since plastic clips are in the way on the left edge, we move the panel a little to the right and perform the operation with a screwdriver on the left side.

Carefully remove the block as far as the steering column allows.

Then we crawl into the niche with our hand and unfasten the 3 chips from the terminals, remove the cotter pin and disconnect the daily odometer drive cable, unscrew the speedometer cable, and by moving it to the right we take out the entire instrument cluster.

Since the plastic contact chips are attached to the board with aluminum rivets, we drill them out with a drill with a drill bit 2-2.5 mm thick. This must be done carefully so as not to scratch the tracks and not to carry chips inside the panel.

The second half of the rivet remains in the housing and can be removed either by removing the light bulbs or drilling a small hole in the corner of the housing. Only then should this hole be sealed with sealant to prevent dust from entering.

So, let's start soldering the contacts, treat them with fine-grained sandpaper if necessary, apply flux and solder in 1-2 directions, or in a circle.

You can also solder the connections with the nuts, having previously tightened them, and the junctions of the diodes.

Soldering areas can be treated with a special varnish for reliability.

We put the chips in place in the same way as they were originally and fix them with rivets, if possible, or with ordinary galvanized self-tapping screws with a flat head 10-15 mm long.

Now we put the panel back in the order of removal. We also prudently inspect the wiring harnesses and chips to see if there are any short circuits or contact oxidation, and check the ground.

Before reinstalling the panel, thoroughly wipe and inspect it. The resulting connections can also be further tested with a multimeter or an indicator lamp connected to the battery.

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

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.

The most common reasons for dismantling

What are the dashboard lights on the Lada Kalina?
There are a lot of reasons for removing the instrument panel on a VAZ 2107, and some of them can be called banal, but nothing can be done. The most common reason when you need to remove the instrument panel is a burnt-out backlight bulb. Replacing light bulbs in the dashboard of a VAZ 2107 is carried out only when dismantling the device, and this procedure is simply impossible to perform otherwise.

The dashboard on the VAZ 2107 must also be removed for a number of the following reasons:

1. Malfunction of pointer indicators.
2. Failure of the instrument lighting, as well as lack of functionality of the arrow indicators.
3. Replacing the device with a new one, for example, if a digital panel is installed instead of the factory instrument panel.
4. Tuning or upgrading the device.

As practice shows, most often the need to dismantle the dashboard arises precisely because the backlight bulb burns out. If the device is dismantled for this reason, it is recommended to immediately replace conventional light bulbs with LED ones.

We recommend: Replacing rear brakes with disc brakes on a VAZ 2107

Required Tools

Before starting work, you will need to prepare the necessary tools so that you do not have to be distracted during the process. Despite the fact that the work of removing the device in question is quite labor-intensive, to implement it you will need a small set of tools, including:

1. Phillips and slotted screwdriver.
2. Electrical tape to indicate chips that are disconnected from the device.
3. Work gloves for unscrewing the speedometer cable.

When all the tools are prepared, it remains to make sure that the parts and elements that are planned to be installed or replaced on the dismantled device are available. After this, we proceed to perform the main part of the work.

Instructions for removing the dashboard on a VAZ 2107

Initially, it should be noted that the process of dismantling the tidy on VAZ 2107 cars, the injector and carburetor are identical, therefore the instructions described below are appropriate for sevens of all years of manufacture. Having prepared to carry out the work, you can proceed by following the following sequence:

1. First you need to turn off the power to the car, for which you remove the negative terminal from the battery. This must be done, since the work will be carried out in the electrical part, and the likelihood of a short circuit occurring is quite high.
2. Next, we move into the interior, and using a slotted screwdriver, we remove three caps from the levers responsible for the operation of the heater.
3. 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).
4. 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.
5. 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.
6. 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.
7. Next you need to disconnect the speedometer cable. It is secured with a special nut, which can be unscrewed by hand.
8. 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.
9. The supply hose is removed from the economizer fitting. This cable is located on the left side of the device.
10. After all the chips, cables and wires are disconnected from the device, you can dismantle it.

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

they are inserted instead of standard light bulbs. But it’s stupid to insert them into devices instead of ordinary lamps (they won’t shine normally). So, we take out the devices and disassemble them. To do this, use a screwdriver to bend the shiny ring around the perimeter. So that it can be removed from the device. The ring will naturally deteriorate, but this will not be visible from behind. We remove the ring. And remove the glass from the device. There are two nuts or screws on the back of the device; unscrew them and remove the device from the housing. Next we study small instruments (in the case of a five-point torpedo this is a voltmeter), the visible part of the scale, more precisely the scale and the dark lining above it. There is a distance between them into which we will push the diode. We take a drill with a drill bit of 7 and make a hole like this from the very bottom of the scale.

And we glue the LED onto the second black cover with sealant. Like this

and in the body of the device we drill a hole in order to bring the wires from the diode into it. Then, once the sealant dries (in order for it to dry faster, I used an ordinary hair dryer), we assemble the entire structure. The hole we drilled will not be visible, just like the diode. It is hidden under the cover.

We put glass with rings on the device. And clamp the shiny ring. To do this, it is better to use the same screwdriver; I do not recommend using pliers because... They will spoil the outside of the shiny ring. Next, we connect the wires from the diode to the standard backlight wires on the devices, and throw out the standard light bulb. We don’t need it and it’s even contraindicated. Let's test what happened.

So the halo below in the photo is just the highest sensitivity of the camera to light. Well, in fact, this halo is not visible. But the scale and needle are clearly visible. Well, that’s great in my opinion. Now we are dismantling huge devices. They are disassembled in the same way as small ones. We solder 4 LEDs on the wires and glue them with sealant into the housing.

I had a blue filter in the tachometer housing, so I left it. If yours is greenish, then break it out. I taped the outer ring of the visor on the inside with tape foil

This is not necessary, but if possible, it is better to glue it. will reflect light better. We drill a hole in the housing and insert the wires from the diode into it and bring them out, and also connect them to the wires of the standard light bulb. Instead of the standard light bulb, we install a blue diode lamp. By the way, in the speedometer housing near this lamp I had a partition; I broke it out so that the light could spread inside the device better.

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.
