VAZ 2114: instrument panel backlight does not light up - 5 reasons and solutions

Operating a car without working instrument lights becomes uncomfortable, so in this article you will find 5 reasons why the lights may go out. In a situation where the backlight of the VAZ 2114 instrument panel does not light up, it is difficult to track the readings of engine temperature, fuel level, tachometer and speedometer, so the problem should be resolved promptly.

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.

Wiring

Damage and rupture of wires in the power supply system of the on-board network is not uncommon on a VAZ 2114 car. To locate the disconnection point, it is necessary to test all possible wires that can be found surrounded by the instrument panel illumination. In addition, the light bulbs may not light due to the formation of oxide deposits on the pads. To fix the problem, you will have to dismantle it and clean the entire contact group.

Fuse

Before you start calling the electrician of the VAZ 2114, the fuse box must be dismantled. Otherwise, the diagnostics will not be complete and will not reveal a complete picture of faults in the instrument panel lighting system. The cause of breakdowns should be sought both inside the electrical wiring distribution system and outside - in the seat. If during testing it is determined that the module is faulty, it should be replaced with a new one, since such equipment simply cannot be repaired.

The board is damaged

A violation in the electrical circuit of the dashboard system board on the VAZ 2114 is the most serious problem of the above. Despite the fact that many radio enthusiasts still repair and eliminate this defect, in practice it is better to immediately replace it with a new one. The main reason that the backlight does not light in this case is a previous short circuit in the circuit. External signs of this will be as follows:

1. If the light source is an incandescent light bulb, the wiring connection to the board will be black.
2. If LED elements are installed, a darkened junction between them and the base will indicate the destruction of the microcircuit.

Why do the dimensions and instrument lights go out on a Chevrolet Lacetti?

The instrument panel lights have gone out.

First, let’s find the connection between the dimensions and instrument lighting.

Fuse box location.

Guaranteed short circuit

However, in 99% of cases it turns out that if the dimensions and instrument lights do not light up, then replacing these fuses will do nothing and their test will show that everything is in order with them.

Attention. Before replacing the glove box light bulb, be sure to remove the negative terminal of the battery, otherwise the instrument panel light may go out.

The fact is that if you do not remove the negative terminal from the battery and start disassembling the glove compartment, a short circuit in the glove compartment illumination circuit is guaranteed - the cartridge contacts will inevitably be shorted to ground if you do not turn off the power to the car.

Even if we did not disassemble the glove compartment, but the side lighting and instrument lighting disappeared, with a high degree of probability the wiring harness leading to the switch and to the glove compartment illumination could become frayed and shorted, which would also cause a short circuit and blown fuse F21. He is responsible for the rear fog lights.

If you do everything correctly, the dimensions will light up again.

MAIN PANEL ELEMENTS

The main place on the dashboard is reserved for the tachometer and speedometer, the fuel quantity sensor and the current fluid temperature in the cooling system. Let's look at the main symbols on the VAZ 2114 panel in more detail.

Tachometer

The VAZ 2114 tachometer is a pointer device, the signal to which is sent by the on-board computer of the fourteenth. The tachometer displays data on the number of revolutions of the crankshaft at the current time. The tachometer is divided by scales into 5 units, every second of which is digitized. The maximum numerical value of revolutions is 80.

To find out the actual engine speed when the car is moving, the tachometer indicator must be multiplied by 100. For example, if the arrow is located at 40, then the crankshaft is performing 4000 revolutions per minute.

The manufacturer has indicated a critical speed value, upon reaching which the engine of the fourteenth may fail due to excessive load. It is highlighted on the device with red shading; this value ranges from 6000 to 8000 rpm.

Under the tachometer there is an electronic window, which displays data about the current time and ambient air temperature.

Speedometer

The fourteenth has an induction dial speedometer, which is located on the right side of the dashboard. The speedometer is also divided into sectors, the division size is 10 kilometers. The maximum mark is 200 km.

The speedometer operates from a speed measurement sensor located inside the gearbox. It is worth considering that all induction speedometers, including the one installed on the fourteenth, have an acceptable error level of 5 km/h.

At the bottom of the speedometer needle there is an electronic screen on which you can see data on the total mileage of the car and the mileage from the last starting point. The driver himself can set the starting point; for this, under the number 200 on the speedometer there is a manual switch that resets the current mileage count to zero.

Gasoline quantity sensor

On the right side of the instrument panel of the VAZ 2114 (the instrument panel of the VAZ 2114 and the designation of the indicators on the instrument panel of the VAZ 2113 are completely similar to the fourteenth model) there is a dial gauge for the current amount of fuel in the gas tank.

The sensor scale is divided into three marks: 1 – full tank, ½ – tank half full, 0 – empty tank.

Next to the sensor there is a color indicator - a light bulb that lights up orange when the fuel level is close to a critical minimum. When the light comes on, you need to refuel the car within 20-30 kilometers.

Cooling system fluid temperature sensor

The coolant temperature sensor is divided into gradations of 20 units. The minimum temperature is 50, the maximum is 130 degrees. The critical temperature zone starts at 105 degrees and is marked with red shading.

If the coolant of the fourteenth boils, then you must immediately stop the car and turn off the engine, since driving in this mode is fraught with serious troubles, even complete engine failure.

If the temperature sensor on the VAZ 2114 dashboard does not work, you need to check the wiring through which the sensor is connected to the coolant container. It is also possible that the sensor contacts may oxidize; they must either be wiped with a solvent or the sensor replaced with a new one.

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.

VAZ 2114 devices do not work

If on a VAZ-2114 car on the instrument panel none of the indicators installed on it work (speedometer, odometer, tachometer, fuel level and coolant temperature indicators), then the first thing the driver will have to do is check the integrity of fuse F3, which is located in the mounting block. If it has burned out, then before replacing it, you need to find the reason why it burned out, otherwise the newly installed new fuse will have the same fate as the previous one. Most often, fuses burn as a result of a short circuit.

Even if the fuse is intact, then do not be lazy to take it out and check the condition of the contacts. There are cases when the contacts oxidize, and the electrical circuit in this place is interrupted. After making sure that the fuse is intact, the next step is to check the ignition relay, which is located inside the car to the left of the steering column. It is attached to a pin upside down. In the block where this relay is inserted, you can try to short-circuit the power wires using a jumper. If the instrument panel comes to life, the ignition relay will have to be replaced.

If the ignition relay is working properly, there are only two possible reasons for the instrument panel not working: the ignition switch and the mounting block. Before installing the ignition relay on the VAZ-2109 car, the lock contacts burned quite often, and they had to be cleaned by disconnecting the contact group from the lock itself. After changes were made to the principle of supplying voltage to the ignition switch, its contacts began to burn very rarely, but the likelihood of this phenomenon still remained. On the mounting block, in its board, tracks may burn out; in order to see this, the mounting block will have to be removed from the car.

In addition to the reasons listed above, which can lead to failure of the instrument panel, it is also necessary to check the reliability of fastening the ground wire.

Hello! Today, on the 14th, I changed the main lighting bulbs in the cabin and after that the instrument readings stopped showing readings of revolutions, speed, fuel level and fluid temperature... I replaced the F3 fuse as written on your website and everything began to show. But the lights still don’t light up in the cabin. Thank you!

the person clearly explained the problem +1 to him. I also accidentally shorted the interior lighting contacts.....

The car starts, but the instruments do not respond! + Turn signals and wipers do not work. The relay and front are normal. Give me some advice ;)

Finding the cause and restoring the light

Rear fog lamp fuse.

What do the glove compartment and rear foglights have to do with it? The 15-amp fuse F21 is connected to the glove compartment lighting and the battery saving mode module. If a short circuit occurs in the circuit, it is this fuse that blows, which supplies power to the main battery block fuse.

This fuse is marked ef1 (rated 30 A) and is installed in the mounting block under the hood of the car. In addition, it protects circuits F13, F14, F15, F16, F21, F22, F23 and F24, and these circuits contain the side lights and dashboard lights.

Check algorithm for Chevrolet Lacetti

Therefore, to troubleshoot the problem we do the following:

1. Check to see if the glove box light is working. If it doesn’t work, we disassemble the glove compartment (after having removed the negative terminal from the battery), connect the power wires to the switch and the light bulb, if necessary, look for a break or short circuit and fix the problem.

   First, look at the glove compartment lighting.

2. We check the integrity of fuses F4 and F6, they are located on the left, at the end of the front panel in the cabin, in the interior mounting block. If necessary, replace them with ones of equal nominal value (10 A).

   We check fuses F4 and F6 for integrity.

3. We check the integrity of fuse F21 with a rating of 15 A, which, according to the diagram, is responsible for the operation of the rear fog lights.
4. We check the 30 A fuse EF1, which is installed in the engine compartment mounting block, and if necessary, replace it with a similar one.

   There is also a fuse box under the hood.

5. Next, you need to get to the instrument panel and check the integrity of the lamps on it.

   Rear side of the instrument panel.

6. If all the fuses are intact and the lamps too, but the problem is not solved, most likely the problem is in the energy saving module. Its catalog number is 96408390, it is located in the engine compartment mounting block. It is extremely rare for a module to fail, but it is possible.

The light in the interior of the VAZ-2115 does not work: possible reasons

Lighting in the VAZ-2115 is one of the most important components of comfortable movement by car at night. If the interior light does not work, the driver faces a lot of inconvenience.

The light emitted by street lamps will not help you find the desired item in the glove compartment, therefore, it is best for the driver to take care in advance that all the light bulbs and other components of the car’s electrical equipment work stably and reliably. But what to do in a situation if the lighting fixtures in the interior of a VAZ-2115 for some reason refuse to fulfill their duties?

The main reasons for the lack of lighting in the cabin

Inside the VAZ-2115, the manufacturer often installs one lamp located directly on the ceiling and individual lamps. It is attached using fasteners and is activated when the doors are opened. Drivers have been familiar with this principle of operation of a lighting device since the “classic” times. The lamp can also be turned on and off manually using a switch located on its body.

The lampshade and other lighting fixtures are part of the electrical system, therefore, if any malfunctions occur with the light, you should start looking for the problem from the electrical circuit diagram. Most drivers prefer to have their car electrically repaired, but such a nuisance can be fixed on your own. To do this, you need to arm yourself with a minimum set of tools and the circuit itself.

The main reasons for the lack of lighting inside the car are:

• Burnt out light bulbs;
• Breakage inside the lampshade;
• Relay or fuse problem;
• Breakdowns in the wiring.

When the reason why the lighting fixtures have stopped functioning properly has been determined, you can safely move on to fixing the problem yourself. As a rule, such work does not cause any particular difficulties for novice drivers. All you need is basic knowledge of how automotive electrical equipment works.

Bulb

The principle of triggering the light elements in the cabin is simple. There are limit switches on the body pillars on all sides.

When the door is opened, this small part causes the contact to open, which gives a signal to turn on the lighting. When you open the door on 2114, only the main lamp turns on. Frequent opening of the door and constant activation of the light bulb leads to its gradual wear.

As soon as the life of the light bulb runs out, it burns out. You can check the integrity of the light bulb yourself. It is enough to lift the plastic cover of the main light source and the insides of the illuminator will be before your eyes.

The driver's light has a slightly different form of light bulb with a socket - r5w with a power of 5 Watts.

It's a little more difficult to change. It is necessary to use a screwdriver to pry off the body of the fisheye, and then remove the wire block. Next, press the latches on both sides of the case and remove the r5w base.

If after the replacement procedure the interior lighting of the VAZ 2114 does not work, check the wiring.

How to disassemble the dashboard of a VAZ 2114

Before embarking on this complex process, the driver must carefully familiarize himself with the design and arrangement of the instrument panel on his car. When disassembled down to the cogs, it looks like this:

If you carefully study this diagram, it becomes clear how to remove the panel on a VAZ 2114. Having determined the order for yourself, you can begin the process.

Using a Phillips screwdriver, you need to unscrew the three screws holding the left console screen

For convenience, when doing this work, it is better to use a screwdriver with a short handle and blade. When removing the screen, carefully remove the lower edge of the trim from the body bracket. The right console screen is secured with five self-tapping screws. Using a Phillips screwdriver, carefully unscrew all the screws while holding the trim with your hand. Remove the screen without allowing it to get caught in the wiring harnesses that are hidden behind it. Disconnect the ground from the battery by disconnecting the connectors. If your car has a radio, disconnect it from the main bundle of wires by pulling out the connecting block

If there is no radio installed on the car, then simply pull the wires out of the panel; they should be closed with a plug. Be sure to turn off the cigarette lighter and remove the socket with the ashtray light bulb. Remove the handles from the heater damper control levers. To make the process easier, pry them off with a flat-head screwdriver. Despite the apparent simplicity of this item, removing the handles from the levers can take a lot of time. To do this, a clear example is given of how this should be done on a removed unit. Remove the electric heater fan handle by simply pulling it towards you. Unscrew the self-tapping screws with a cross-shaped head that secure the instrument panel to the brackets on the right and left with a screwdriver. In the window on the instrument panel, where the instrument unit is located, there are two self-tapping screws at the top and two at the bottom - under the window. It is necessary to turn them out, loosening the cover (2) and the shield (8). Pull out the plug and unscrew the self-tapping screw located behind it. Remove the two self-tapping screws from below that hold the trim and remove it. Having marked the wires suitable for the switches, disconnect them. Unscrew the bolts from the steering wheel bracket. Use an “8” key to unscrew the screws of the lower bracket mounting. Unscrew the self-tapping screw and remove the light guide. Remove the fasteners from the heating control unit and remove the cartridges from the back of the unit. remove the decorative insert, removing all external parts. Unscrew the nuts with a key set to “21”. Remove the hydraulic corrector illumination. Unscrew the upper and lower fastenings of the panel, and remove the fastening to the cross member on the left side. Now you can remove the VAZ 2114 torpedo. Installation is done in the reverse order.

In order to clearly see the whole process in motion, you can watch a video on how to remove the dashboard on a VAZ 2114.

Replacement - order

Having figured out how many lamps the dashboard contains, it won’t hurt to find out how to replace them on the 2114th model. The procedure itself is not very complicated, but extremely troublesome.

1. First of all, you will need to disassemble the shield. The radio tape recorder, heater and ventilation control levers are removed from it.
2. Then unscrew the screws holding the decorative panel trim. Before doing this, the steering wheel should be moved to the lowest possible position - this way it will not interfere.
3. Find the screws - there are five of them, and they are closed with plugs. Carefully pry the latter with a knife and pull it towards you. After removing the screws, pull the VAZ-2114 panel towards you.
4. Now you need to unscrew the two screws holding the instrument panel itself. This is done with a Phillips screwdriver.
5. Afterwards, the panel is lowered and the opened terminals of the wire loops are disconnected. Then the element is freely taken out.
6. Next, the damaged light bulb is pulled out - turn it 90 degrees in any direction until the protrusions on the socket fit into the grooves. Then all that remains is to remove the product from the base and put a new one in its place.

As noted above, so that the 2114 panel does not have to be disassembled again after some time, it is advisable to immediately replace all the lamps. This will also ensure an even glow of all elements.

The backlight of the VAZ 2114 instrument panel does not light up: do-it-yourself repairs

The dashboard on the VAZ 2114 allows the driver to control engine data, monitor the remaining amount of fuel, his speed, and other data. The panel should be maintained in working condition so that the backlight not working does not cause discomfort, and the sensors show real values.

Bright backlight

But quite often, VAZ 2114 owners discover that the instrument panel lights do not light up. If such a situation occurs, appropriate action should be taken immediately to eliminate it.

Why the instrument panel does not work

Disassembled dashboard

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).

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.

Panel disassembly diagram

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.

Selection of light bulbs

Wiring ringing

Today the market offers a wide range of lamps that can be used for the dashboard of the VAZ 2114. Among the most well-proven devices, we note a few. Their name and cost are presented in the table.

Replacing the backlight

In analysis

To improve the quality of your dashboard lighting, it is advisable to install new LEDs in place of the old ones. They provide excellent illumination, consume minimal energy, and guarantee a high level of data reading.

1. Buy a set of LED lamps, having previously calculated the number of devices needed for each sensor.
2. After removing the block, install the resistors and lamps in specially designated places on the VAZ 2114 - in the sockets. To dismantle the cartridges, they are carefully unscrewed counterclockwise. New sockets are installed in their place and light bulbs are inserted. Respect the polarity and position the LED heads. They will have to be carefully ground off.
3. Connect the power and check how the new backlight works.
4. Reassemble step by step. Be sure to route the wiring to the board and carefully secure it to it. This way, the backlight components will not interfere with the reassembly process.
5. Make sure the instrument panel arrows are positioned correctly. When trying to quickly complete a job, they often become deformed and bent.
6. The backlight structure is fixed with screws.
7. The power for the LEDs is connected to the power supply for the light bulbs, the arrows are put on and set to zero.
8. Using the on-board computer, check the operation of each sensor and device. If the IDs are functioning correctly, return the instrument panel to its original condition. That is, assemble the entire assembly.

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 rear wall is carefully removed along with the board, which is attached to the wall with plastic latches. The contact board in the VAZ 2114 dashboard is held on by simple plastic latches
4. The latches are bent with a knife, the damaged board is removed and replaced with a new one. The panel is then reassembled.

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.

Checking the indication

There are 5 indication modes:

• off – when the key is not in the ignition switch;
• standby mode - the BSK VAZ 2114 goes into it when the key is inserted into the ignition, but remains in the “Off” position; if you open the door, an error about a forgotten key will be displayed. You must close the door or remove the key to stop the horn;
• test - turns on when the ignition key is turned to the “Ignition” position. A sound signal and the turning on of all the system lights indicate that the device is working properly. Afterwards, all systems are tested, while the sensors are turned off;
• preliminary test - after testing is completed, the VAZ 2114 display unit, if there are malfunctions, the diode responsible for a certain parameter begins to blink for 8 seconds, after which it lights up evenly until the key is returned to the “Off” position. The blinking of the indicator is accompanied by a rhythmic sound signal;
• test with the engine running - this mode for BSK 2114 is the final stage of control. Monitoring of sensor parameters goes into sleep mode. It only carries out periodic additional monitoring of the vehicle’s performance. All malfunctions that occur in this mode are remembered until the end of the trip and the lights glow steadily.

The dashboard of the VAZ 2109 does not light up

Common instrument panel faults

The instrument cluster on the VAZ 21099 or 2109 is a fairly reliable unit. However, even this can fail over time.

The main malfunctions characteristic of the VAZ instrument panel:

1. The lights on the instrument panel of the VAZ 2109 stopped lighting. If only a few light bulbs refuse to work, then most likely the reason lies in their burnout. If the instrument panel lighting stops working completely, then most likely the problem is a poor power supply. As practice shows, power problems are usually caused by either damaged wiring or oxidation of contacts at connections and connectors. If this is the case and the backlight does not light up due to oxidation, then you can get rid of this problem by cleaning the contacts or replacing them. If the problem lies in the lighting sources, then replacing the lamps will solve it.
2. Another problem, oxidation on the circuit board, is common in older vehicles or vehicles that have moisture. Due to oxidation of the board, the backlight and some instruments may not work, in particular, fuel level and coolant temperature controllers, tachometer, etc. If the needles do not rise on the tachometer, speedometer, fuel consumption sensor and generator voltage, or they work chaotically, then you need to carry out a full check of the dashboard.
3. VAZ 2109 cars are characterized by the problem of a non-working speedometer. As a rule, it appears as a result of wear of the cable connected to the box, or due to repairs to the device and its incorrect connection. If the cable is worn out, then you just need to replace it, there is nothing complicated about it. The main thing is to connect the cable correctly so that its tip fits exactly into the groove on the tidy speedometer.
4. Damage to the board itself. Such a malfunction occurs quite rarely, but, nevertheless, it should not be forgotten. If the structural board fails, the shield will have to be repaired, but if this does not help, then it will need to be replaced.

Instrument panel pinout

VAZ 2109, 21099 cars can use low and high center consoles, as well as Europanels. Depending on the type of torpedo, the combination of the instrument panel and its pinout, as well as the position of the indicators, will be different. Below are photos and symbols of components on instrument panels with different torpedoes.

Photo gallery “Designation of indicators on dashboards”

If you decide to tune your instrument panel, then most likely you will be interested in knowing what options exist for doing it. The tuning shield, as you know, pleases the driver’s eye, so this issue is relevant for many car owners.

Which bulbs are suitable for the 2114th model

In general, the current legislation provides for quite serious sanctions against motorists who dare to make any changes to the design of the vehicle at their own discretion. In accordance with the rules, they are obliged to replace components and assemblies only with analogues of those chosen by the manufacturer. Failure to comply with this requirement provides grounds for punishment of the driver.

Thus, more and more owners are installing LED lamps on their 2114 Ladas instead of the standard halogen ones. This choice is easy to justify. In particular, they:

• consume approximately 8-9 times less electricity, which means the load on the on-board power system is reduced;
• last 5-10 times longer;
• give brighter light;
• practically do not heat up.

Finally, the dashboard looks much more attractive, because the light bulbs can be of different colors - blue, red, green, etc.

The problem is that LEDs cost about twice as much, but this disadvantage is more than compensated by their longer lifespan. In addition, LED lamps are becoming cheaper every year.

The right console screen is secured with five self-tapping screws. Using a Phillips screwdriver, carefully unscrew all the screws while holding the trim with your hand. Remove the screen without allowing it to get caught in the wiring harnesses that are hidden behind it.

Disconnect the ground from the battery by disconnecting the connectors. If your car has a radio, disconnect it from the main bundle of wires by pulling out the connecting block

If there is no radio installed on the car, then simply pull the wires out of the panel; they should be closed with a plug. Be sure to turn off the cigarette lighter and remove the socket with the ashtray light bulb. Remove the handles from the heater damper control levers. To make the process easier, pry them off with a flat-head screwdriver.

Despite the apparent simplicity of this item, removing the handles from the levers can take a lot of time. To do this, a clear example is given of how this should be done on a removed unit.

Remove the electric heater fan handle by simply pulling it towards you. Unscrew the cross-head screws securing the instrument panel to the brackets on the right and left with a screwdriver

In the window on the instrument panel, where the instrument unit is located, there are two self-tapping screws at the top and two at the bottom - under the window. It is necessary to turn them out, loosening the cover (2) and the shield (8).

Pull out the plug and unscrew the screw located behind it

Remove the two screws from the bottom that hold the trim and remove it.

Having marked the wires suitable for the switches, disconnect them.

Unscrew the bolts from the steering wheel bracket. Use an “8” key to unscrew the screws of the lower bracket mounting.

Unscrew the self-tapping screw and remove the light guide. Remove the fasteners from the heating control unit and remove the cartridges from the back of the unit.

remove the decorative insert, removing all external parts. Unscrew the nuts with a key set to “21”.

Remove the hydraulic corrector illumination. Unscrew the upper and lower fastenings of the panel, and remove the fastening to the cross member on the left side.

Now you can remove the VAZ 2114 torpedo.

Installation is in the reverse order.

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.

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.

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.

In the block, the fuse is located on the right and is designated as F10. It is responsible for the dashboard illumination, the operation of the side lights and the license plate lighting. On early VAZ 2114 models, fuse F10 was brown or red.

On early VAZ 2114 models, F10 fuses were brown; later cars began to have green fuses. 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.

What else is this fuse responsible for?

If the instrument backlight fuse on a VAZ 2114 blows, the left side lights, license plate lights, ashtrays and other above-mentioned elements should also not work. To diagnose a malfunction, you need to find this fuse in the mounting block and inspect it. Often the defect is clearly visible externally.

You can also check it with a multimeter. If there is voltage at one end of the part, but not at the other, it has failed. Replacing an element with a known good one also helps diagnose a breakdown. If everything works after this, the reason has been established correctly. The fusible element is cheap. Therefore, you should look for the cause of the breakdown by replacing it. This usually helps solve the problem. If this does not help, you need to consider other faults.

How to identify a malfunction

There was no indicator screwdriver, just a small flashlight and some thin copper wire. It was decided to identify a blown fuse in the mounting block by dialing. For this diagnostic method, it was necessary:

1. disassemble the flashlight;
2. cut one wire (in the flashlight circuit);
3. add two small pieces of wire (about the same cross-section) to the ends of the cut wire;
4. close the flashlight key (turn on the flashlight).

As a result, the result was a homemade device for testing individual circuits and, in particular, for testing fuses in the mounting block located under the hood on the driver's side. You, of course, understood how to use such a “device” (two wires with bare ends are taken, which are subsequently connected to the fuse contacts). The two wires brought out from the flashlight serve as “device probes”, when closed, the flashlight light comes on.

A blown fuse was subsequently found (identified) in the mounting block, this is a 7.5 A fuse F10, which is responsible for lighting:

• devices,
• engine compartment

and car number.

There was no spare fuse of the same type in reserve and, accordingly, the question arises: How can I replace the fuse?

How can I replace the fuse?

In the current hopeless situation, it was necessary to install a piece of thin copper wire instead of a fuse, after which the instrument panel and other current consumers began to work properly. Of course, this is not the best way to fix the problem, but nevertheless, after fishing we arrived home safely. Upon arrival home, the car driver installed a working fuse of the appropriate color.

Replacing the fuse on a VAZ 2115

Each fuse that is included in the electrical circuit of the car must correspond to its rated current value, which thereby protects current consumers for a particular circuit from malfunction.

To make it easier to find a fault both in the lighting and in other consumers, the manufacturer provides colors for the fuses. The schematic representation of the mounting block (Fig. 1) clearly shows the location of the fuses and relays included in the electrical circuit of the car.

Fuse colors

There is no need for any explanation regarding the color marking of the fuses; everything already looks quite clear. Each fuse with a certain color will correspond to the maximum current value.

Let’s say that if the power windows malfunction, you must first check fuse F6 with a maximum current value of 30 Amps, and then (depending on the circumstances), check the remaining connections in this circuit.

That's all for now. Follow the section.
