The backlight of the VAZ 2114 stove does not work: how to replace the bulbs

Usually, a heating device, if it is not a fireplace, requires high-quality heat release, and not pleasing the eye with lighting delights. But for a car heater, the backlight is not much less important than the heat it emits. Its front part, together with the switch, being a component of the car’s dashboard, should facilitate clear orientation of the driver and be accessible to his gaze at any time of the day, especially in the evening or at night. That is, the lighting of the stove carries a purely functional load, which, however, does not in the least prevent it from being beautiful. This is exactly what many drivers are striving for today, replacing standard backlight bulbs with LED strips.

What kind of light bulbs are there?

In the VAZ 2114 car, two lamps are responsible for interior lighting. One of them, also called the navigation one, is responsible for individual lighting and is located in the front part of the ceiling between the sun visors.

It uses an A12-4-1 (T4W) lamp with a power of 4 W.

The general interior lighting of the VAZ 2114 is also located on the ceiling, but a little deeper: between the pillars to illuminate the entire interior.

The manufacturer installed a 5 W AC12-5-1 (C5W) light bulb in it.


Lamp used in a general lighting lamp

Both bulbs are ordinary incandescent.

How to remove the lampshade and replace the lamp

Since two lampshades are responsible for interior lighting in the VAZ 2114, we will change the light bulbs in both.

General lighting lamp

Let's start with it, since replacing the light bulb in it is simple and won't take much time. First, a little theory. You can turn on this lamp in two ways: by opening any of the doors (mode 1) or by pressing one of the edges of the lamp (mode 2).

That is, the lampshade in this lantern swings around the central axis and acts as a switch.


Operating principle of the lamp switch

In the photo the numbers indicate:

  1. Lantern body.
  2. Glass shade.
  3. Swing axis.

In order to remove the lampshade, it is enough to press the side of the housing at the swing axis so that the ebb on the glass comes out of the groove in the housing. This can be done with a flathead screwdriver or even your finger.


Pressing out the side of the flashlight body with your finger

First we remove this edge of the glass from the lantern, and the opposite one will come out on its own.


Removing the glass of the general interior lighting of the VAZ 2114

We remove the glass and observe the light bulb, which is clamped by two spring contacts.


Interior light bulb

We press the burnt out light device towards one of the contacts and remove it.


Removing a burnt out light bulb

We install a new one in place of the burnt one, simply snapping it into the contacts of the cartridge. We install the glass in the same way as we removed it: we insert one ebb on the glass into the groove of the body, snap the other one, slightly pressing the edge of the lantern with your finger.

Individual lighting lamp

Here we need a small flathead screwdriver to work. We insert the screwdriver into the slot, as shown in the photo below, and snap the flashlight out of the holder.


Removing the navigation light VAZ 2114

We take out the flashlight and see two blocks placed on the cartridge (marked with arrows). We remove them by simply pulling them out. In principle, you don’t have to remove the pads, but with them removed you won’t have to work with your hands suspended.

Power connectors can be removed for convenience

Now we press out the latches one by one, marked with arrows in the photo below, and gradually pull out the cartridge.

Important! The latches, like the cartridge itself, are very fragile - ordinary organic glass. We squeeze it very carefully, take our time and be sure to take turns, gradually pushing out the cartridge. If the latch breaks, the cartridge can be thrown away.

The socket together with the light bulb is in our hands.

Removed lamp socket for individual lighting VAZ 2114

Slightly recess the lamp, turn it counterclockwise and remove it. We also recess the new lamp and turn it clockwise.

We install the socket with the new light bulb in place, making sure that both latches work, put the power blocks on its contacts (polarity may not be observed), install the flashlight in the standard socket and press it until it snaps into place.

The lights still don't come on - other reasons

It often happens that after disassembling the lamp, the lamp turns out to be working, but the lighting does not work. What can be done in this case? Let's try to find the problem on our own.

Diagram of the ceiling lamp for the main interior lighting of the VAZ 2114

  • First, let's take a look at the circuit diagram of the main interior lamp of the VAZ 2114.
  • Wiring diagram of the main interior lamp VAZ 2114
  • Here:
  • X1 – lamp lamp;
  • SW1 – mode switch built into the lamp;
  • SW2-SW5 – limit switches in door pillars;
  • F – fuse in the mounting block.

As can be seen from the diagram, one terminal of the lamp is constantly under voltage of +12 V. When any of the doors is opened, the corresponding limit switch is closed, and the second end of the lamp is connected to the body (this is the minus power) - the light comes on in the cabin. If you move switch SW1 to the opposite position, lamp X1 will light up regardless of the state of the doors. Thus, if:

The light doesn't come on at all . The fuse, lamp socket or switch SW1 is faulty. It is easy to check the serviceability of the fuse. Together with the interior lamp, it powers the brake signal lamps, navigation lamp, luggage compartment lamp, ignition switch illumination, and trip computer. If all this works, then the fuse is good.

If everything goes out at once, then open the hood and find the mounting block. It is located in the engine compartment just behind the windshield opposite the driver. In the photo below the block is marked with an arrow.

Location of the mounting block in the VAZ 2114

We are interested in fuse F3, marked with an arrow in the photo below.

This fuse is responsible for the interior light

Using the tweezers included in the kit, remove the burnt one, and in its place install a new one of the same rating (10, in some modifications 7.5 A).

Next is the cartridge. He's in full view. We remove the light bulb, inspect the base and socket contacts. We clean if necessary. The switch remains. We will find out what to do with it in the next paragraph.

Mode 2 “Always on” does not work. The reason is either in the switch or in the wire going from the flashlight to ground. It is black. We open the lampshade (see section “How to remove the lampshade and replace the lamp”) and check the condition of the switch contacts. There are 3 of them: the middle one is movable and the two outermost ones are stationary. In the photo below they are indicated as 1 and 2, respectively.

Contacts of the mode switch built into the lampshade

We inspect and clean if necessary. If the contacts are clean, then perhaps the glass does not press the moving contact to the lower fixed contact when switching. We do it with our finger:

Checking the operation of the switch by hand

The light comes on, which means the glass is simply not making contact enough. We bend its tip slightly upward, install the glass and check. If the contacts are OK, but the light does not come on, the problem is in the ground wire.

We take a piece of wire with stripped ends and use it to connect the middle contact of the lamp to any part of the body that is not covered with paint (bolt, screw, etc.).

Fired up? You will either have to look for where the standard wire broke, or simply disconnect it and wire a new one, using only a special car one.

Important! All manipulations with the switch, except for checking (cleaning, bending contacts, etc.), should be carried out only with the battery disconnected, since +12 V is always present on the lamp.

The slightest carelessness and you can lose the fuse, or even burn out the wiring altogether.

Mode 1 does not work correctly . In this mode, the backlight turns on when any of the doors is opened.

There are three options: the light comes on when the doors are closed, the light does not come on when any one door is opened, and the light does not react at all to the state of the doors.

In the first two cases, one of the limit switches is clearly faulty, or the wire running from them to the lampshade is shorted to the body. The third case is a break in the wire running from the limit switches to the lamp.

Let's start with the first option - the ceiling lamp “does not see” one of the doors. We open the “guilty” door and find a limit switch on its counter.

The photo shows that the pusher head is pretty worn out. Maybe this is the reason? Press it with your finger. Is it burning? The problem is mechanical wear. Here you either need to change the limit switch or come up with something else (for how long?). If it doesn’t light up, unscrew the fixing screw and pull out the switch.

Radiator repair

It is quite possible to clean the radiator pipe system from deposits and scale. To do this, you can use the same cleaning products that are usually used in everyday life (“Silit”, “Mole”, Comet). However, any chemically active compositions will do, including Coca-Cola (you’ve probably repeatedly seen materials devoted to this drink regarding its chemical properties). As practice shows, better results can be achieved by working with the radiator removed, but this is not critical. Completely satisfactory cleaning can be performed without dismantling the radiator. The flushing scheme is very simple: the antifreeze is drained, all pipes are disconnected, after which a cleaning agent is poured into the filler neck. Then the engine starts, which, with the heater on, should idle for about 40 - 120 minutes.

After cleaning, the radiator is thoroughly washed, for which you can use running water from a tap connected through a suitable hose. The final stage is to dry the radiator with compressed air (if a compressor is available) or naturally, which will take at least a day. The presence of a leak is a much more serious problem. It can be eliminated by soldering. At the same time, finding a leak in itself can be a time-consuming task, which is unlikely to be accomplished without removing the radiator.

Soldering is also difficult, since the radiator tubes are made of aluminum. For such work you need a very powerful soldering iron, supplemented with special solders and flux. The quality of soldering also depends on the skills of the worker performing such repairs: if they are small, there is a high probability that over time the leak will be restored in the same place. Therefore, it makes sense to replace the radiator with a new one, the cost of which varies within a thousand rubles.

How to replace the dashboard bulbs of a VAZ 2114

The dashboard of the VAZ 2114 car displays data that allows the driver to monitor the condition of the car - fuel and engine oil levels, speed, revolutions and engine temperature.

The panel must always be in good condition, which is the key to the accuracy of the data shown by the sensors and the absence of discomfort caused by non-functioning backlighting. Quite often, VAZ 2114 owners are faced with the problem of the dashboard backlight not working.

The problem is resolved independently, without visiting car services or contacting specialists.

What are dashboard lights for?

VAZ 2114 is one of the highest quality, dynamic and beautiful models of the domestic automobile industry, with excellent technical characteristics. However, it also has its drawbacks, one of which is the dashboard, which is not particularly reliable and of high quality. A common problem with the dashboard is the rapid failure of the backlight lamps.

Working illumination of the dashboard of a VAZ 2114 car

The backlight bulbs provide the driver with various information that allows them to monitor the condition of the car and diagnose possible malfunctions in a timely manner. There may be several reasons for their operation:

  • the battery is discharged;
  • holding the handbrake;
  • lack of fuel in the gas tank;
  • a decrease in engine oil pressure is a reason that requires stopping the car to avoid engine damage;
  • accumulation of water in the filter. Excess liquid is drained to prevent it from entering the pump;
  • malfunctions in the fuel system;
  • engine malfunctions.

Failure of instrument panel lamps may cause the driver to miss a breakdown or malfunction that could cause an accident. For this reason, you should not delay replacing light bulbs.

Why do light bulbs fail?

Before changing incandescent bulbs, you need to understand what caused the dashboard to fail. The reasons why the backlight stops working may be:

  • burnt out incandescent lamps or LEDs stop working;
  • oxidation of connectors;
  • defects and short circuits in the electrical circuit;
  • fuse box failure;
  • deformation of the common contact board;
  • failure of the dimensions system;
  • no negative battery.

Today, the automotive markets offer a wide selection of different lighting devices for the dashboards of domestic cars: both standard lamps and modernized expensive analogues, which allow you to completely change not only the panel, but also the entire interior lighting.

Location of various sensors and indicators on the dashboard

Experts often advise using LEDs instead of standard lamps - they are more reliable, have lower power consumption and have an attractive soft light.

There is a wide range of instrument panel lamps available in the automotive markets.

  • The table below lists the lamps that are optimally suitable for the VAZ 2114 dashboard.
  • Table: Lamps used in the backlight of the VAZ 2114 dashboard
  • The cost of lamps for the instrument panel is low, and the replacement process itself is not difficult.

How to replace light bulbs

Installing new lamps is a simple process that novice car owners can do.

Required Tools

To replace you will need the following devices:

  • Phillips screwdriver;
  • a set of new light bulbs.

To improve the quality of dashboard lighting, it is advisable to replace old lamps with new LEDs - they provide brighter and softer light that does not irritate the eyes, have minimal power consumption and allow you to more accurately read data from devices.

Before you begin installing the lighting fixtures, you need to remove the decorative trim from the music system - the instrument panel and radio on the VAZ 2114 are connected to each other, so this step cannot be avoided. Dismantling is carried out by snapping off the fasteners with a flat screwdriver. The cover is removed from the bottom edge and very carefully, as all the latches can be damaged.

How to disassemble the dashboard

Dismantling the VAZ 2114 dashboard is the first step in the process of replacing backlight bulbs. Without removing the plastic cover it is impossible to get to the lighting fixtures themselves.

Scheme for disassembling the VAZ 2114 dashboard

The dashboard on the VAZ 2114 is disassembled according to the following scheme:

  1. Three self-tapping screws are unscrewed, the lower protrusion and the cover are removed.
  2. There are five screws on the right console trim that also need to be removed.
  3. The screen is removed and the negative terminal is disconnected from the battery.
  4. The wiring harness is disconnected from the cigarette lighter.
  5. The handle is removed from the gear shift lever.
  6. The stove fasteners are removed.
  7. The bolts that secure the steering wheel block are carefully unscrewed.
  8. Decorative inserts, lamp sockets and LEDs are removed from the panel.
  9. The hydraulic corrector illumination lamp is removed using a 21 key.
  10. The upper and lower screws are dismantled.

After completing the dismantling of the instrument panel, the wiring circuit is closed to prevent dust, moisture or dirt from entering it.

Only 8 out of 13 lamps can be replaced in the instrument panel of a VAZ 2114.

Before installing new lamps, remove the plastic cover from the instrument panel

Replacing backlight bulbs

After removing the plastic, you can begin the process of replacing the lamps.

  1. The required number of lamps to replace the backlight of each sensor and panel device is calculated in advance.
  2. Lamps and resistances are installed in special places - sockets - after removing the block. The cartridges are unscrewed counterclockwise by hand, without the use of tools. New ones are installed in the vacant spaces, then lamps are inserted into them. The LED heads are screwed in with correct polarity.

    Placing new lamps on the instrument panel

  3. The power is connected and the functionality of the updated backlight is checked.

    Checking backlights with a multimeter

  4. The instrument panel is being reassembled. The wiring is neatly routed to the board and attached to it, so that the parts will not interfere during assembly.

    The instrument panel is being reassembled with the sensor arrows placed

  5. All arrows of sensors and instruments must be positioned correctly. If you rush too quickly during installation, you may break or bend them.
  6. The entire structure is attached with screws.
  7. The power supply of the LEDs and light bulbs is combined, the arrows are placed in their places and set to zero.
  8. The operation of the panel instruments and sensors must be checked by the on-board computer. If everything is functioning properly, the dashboard is reassembled and returned to its original state.

Experience of car enthusiasts

I finally decided to change the light bulbs in the heater lights, which were not working for me when I bought the car. Before this, I scoured the Internet and found out that there are two ways to replace these light bulbs. The first way is to disassemble the entire torpedo, etc. and so on. The second way is to get to them through the dial of the stove controls. I used the second method. Tools: Phillips screwdriver, small pliers, flashlight for illuminating the lamp replacement process. First, the red and blue socket is removed, the rods under this socket are pushed apart with a screwdriver, and the old light bulb is carefully pulled out with pliers. Then he goes across the road to the nearest auto store, shows the salesman the old light bulb, and buys the same new one. A new light bulb is inserted using the same method. All! The backlight works! Whoever needs it, use this method, everything works. The main thing is that your hands do not shake and do not drop the lamp with tweezers or pliers))))

If, after turning it on, it seems to you that the light is pleasant to the eye, but you want a little more contrast, you can unscrew the plate with the ribbons and mount it again, but not directly to the body, but through small bushings that will help bring the LEDs closer to the scale. As a result, the lighting will become less diffuse.

In order not to remove the entire dashboard, you can limit yourself to removing only the translucent scale on the stove. The method is rough, but effective. To do this, use a thin and wide screwdriver to pry the scale on the right (you can’t do it on the left because of the protrusions there!) and at the same time pull the middle of the scale toward you with your fingers so that it bends slightly in an arc. After this, the light bulb will be visible behind the plastic guides, which must be moved apart. Then, using tweezers with non-slip ends, remove the light bulb from the socket and replace it with a new one. When returning the scale to its place, you need to insert it from left to right, again slightly bending it in an arc.

Easy replacement of light bulbs in the dashboard of a VAZ 2114

Reading time:

Any driver knows how to track the condition of the car: using instrument readings. In the dark, illumination is responsible for their visibility. But all electrical devices have a limited lifespan, including incandescent light bulbs. They are used in the dashboard of the VAZ-2114. Replacing the light bulbs in it is not difficult, but painstaking.

Why lamps burn out or stop working: causes and consequences


Burnt-out lamps complicate the driver’s control over the car’s instrument readings.
The operating conditions of the backlight are not ideal: shaking, temperature changes, possible power surges in the on-board network, and so on. When driving, you must turn on low beam headlights. Along with it, the instrument lighting also turns on. This can shorten the life of the lamps, and over time, not the entire panel is illuminated evenly.

The main danger of lamps burning out in the instrument cluster is that some of them are control lamps. In this case, you may not know about the failure of individual machine components. And uneven illumination looks ugly.

Solution

The stores offer several options for light sources for replacing lamps in the instrument cluster:

  • traditional incandescent lamps,
  • LED in a plastic socket,
  • SMD LED is a more expensive and reliable option, a super-bright diode.


The choice will always depend on financial capabilities and lighting preferences

The number of backlight and control lamps is up to 19 pieces. It varies slightly depending on the design of the instrument cluster and the modification of the vehicle. Many car owners choose LEDs due to lower energy consumption and longer service life.

This backlight is brighter and gives an interesting bluish color instead of the standard green. But due to the design of the diode, the brightness control of the instrument illumination will not work, always turning it on at full power. On a long road trip at night, this can be distracting and irritating to the eyes.

But in any case, the choice of light sources is yours.

If you are going to install LEDs, it is recommended to first check them with a tester for the absence of a short circuit.

Step-by-step instructions for replacing light bulbs in the dashboard of a VAZ-2114

  1. We release the decorative cover of the front panel. For this we need screwdrivers: a short Phillips and a flathead one. Lower the steering column to the lower position using the height adjustment lever to keep it out of the way. The photo shows the mounting locations for the casing:
      There are four screws on the bottom of the visor and above the steering column. Unscrew them with a short Phillips screwdriver.
  2. Using a flathead screwdriver, pry off the decorative cap to the right of the row of switches. There is another fastening screw under it.
  3. Also, remove the handles from the heater switch and damper control sliders by pulling them towards you.
  4. If you have a car radio, you will also have to remove it.


    Unfortunately, complete dismantling is not possible. Arrows indicate locations for removal

  5. Pull the front panel cover towards you. He must move. There is no need to remove it completely - there will be enough space to access the mounting screws on the sides of the instrument cluster.


    Carry out your actions carefully

  6. Unscrew the fastening screws with a long screwdriver. The combination will be released and you can tilt it towards yourself. Pull out the two blocks with wires. Don’t be afraid to mix them up - there is a color marking, and the asymmetrical shape of the connector will prevent you from connecting it incorrectly.


    The arrow indicates the location of the cartridge handle

  7. On the back cover of the instrument cluster there are cartridge handles. Arm yourself with small pliers. This will make it easier to unscrew them. To release the cartridge, half a turn counterclockwise is enough. You can safely take out all the cartridges - they are the same. Next, you can check the lamps with a tester and replace the burnt ones, or replace them all with LEDs at once. Try to ensure that they fit tightly in the cartridge, otherwise the contact will be unreliable.
  8. We reassemble in reverse order. We insert the cartridges into the seats so that the antennae fall into the grooves, carefully turn them with pliers until they stop. We connect both blocks to the connectors of the instrument cluster.
  9. Let's check if all the lamps are working:
      raise the handbrake and turn on the ignition: so let’s check the handbrake, generator, oil pressure and check lamps,
  10. turn on the hazard warning lights - check the warning lamp and direction indicator lamps,
  11. pull the headlight switch lever towards you - temporarily turn on the high beams, check the warning lamp,
  12. turn on the dimensions - see if the scales are evenly illuminated, and if the warning lamp, if any, is on.

This is interesting: We repair DENSO injectors ourselves

If everything works correctly, we fix the instrument cluster and the front panel casing, and replace the heater switch handles and damper controls.


Check the brightness and functionality of all devices

Congratulations, now the instrument lighting and warning lights are working properly, and you will always be aware of what is happening with the car. The overall aesthetics of the front panel will also improve - the evenly lit front panel looks beautiful.

Replaced by removing the panel

For those who do not want to spoil the panel, a method that involves removing it is suitable.

In this case, you will need the same tool as indicated above, except for a metal saw blade.

The main thing here is to have as many Phillips screwdrivers of different lengths on hand as possible.

And then we do everything like this:

  1. Remove the side panels of the center console (see above);
  2. We dismantle the storage box;
  3. Remove the center console trim. To do this, remove the tips of the heating system control sliders and the “knob” for turning on the stove fan. We remove the radio. We unscrew the screws securing the trim - at the top of the center console (hidden by a plug), above the dashboard (2 pieces) and under it (on both sides of the steering column);
  4. Remove the upper part of the steering column casing;
  5. Pull the console trim towards you. We disconnect all the connectors with wiring from it, having previously marked with a marker where each one was located (you can take a photo). After this, completely remove the cover;
  6. Unscrew the screws securing the panel to the body (two screws on each side near the doorways);
  7. We unscrew the screws holding the metal frame of the ECU (at the top under the panel and at the bottom near the floor);
  8. Remove the screws located above the steering column;
  9. After this, the panel is up and towards you;
  10. We move the panel towards us, and then ask an assistant or use a high jack to lift it to provide access to the radiator. You can temporarily put some kind of emphasis;
  11. Disconnect the radiator pipes (remembering to place a container to collect residual coolant);
  12. Unscrew the three fastening screws and remove the heat exchanger.

After that, all that remains is to install a new element and put everything back together.

But here are some nuances to consider:

  • To reliably fix the connection points of the pipes with the radiator, the clamps should be replaced with new ones;
  • It would not be superfluous to coat the joints with heat-resistant sealant;
  • After installing a new heat exchanger and connecting a pipe to it, you should immediately check the tightness of the connection by filling the cooling system with antifreeze. And only after making sure that there are no leaks, you can put the panel in place.

As you can see, the second method is more labor-intensive, but the panel itself remains intact.

In addition, with this method, during assembly, you can coat all joints between the panel and the body with sealant to eliminate squeaks.

In general, both methods are good, but each of them has its own advantages and disadvantages. Therefore, which one to use is up to the car owner to decide.

Replacement without removing the panels, can you see the seams?

Replacing the backlight of the stove Lada 2114 (VAZ 2114)

A dashboard is needed in a car so that the driver can always be aware of the state of the power unit, the amount of fuel in the gas tank, the speed of movement, etc. Any motorist understands without further explanation that it is unsafe to drive a car if the dashboard is faulty. The reasons for the malfunction of the instrument panel may be different, but in today’s article we want to talk about the malfunction of the instrument panel backlight in the VAZ 2114 car.

Basically. Without backlighting of the instrument panel, you can drive in the daytime, but what about in the dark, because without backlighting the driver will not be able to see the readings of a single indicator.

  • Causes of malfunctioning backlight in the dashboard
  • In fact, there can be a lot of reasons. We will name the most common:
  • — incandescent lamps have burned out or the LED group has failed;
  • — connectors are oxidized;
  • — electrical wiring is faulty;
  • — the fuse box has failed or one of the fuses responsible for the panel illumination has blown;
  • — damage to the common contact board;
  • — there is no mass (minus) on the body or the dimensions system is damaged.

One way or another, to detect a malfunction you will have to resort to the help of diagnostic equipment, a tester or a voltmeter. Well, after the cause of the malfunction has been established, you can proceed directly to its elimination.

Troubleshooting steps

Sometimes, in order to determine and eliminate the causes of a malfunction in the instrument panel lighting in a VAZ 2114 car, it is necessary to remove it in order to check the condition of the bulbs, fuses and contact group. If it's all about burnt out light bulbs or fuses, they need to be replaced. The contact group is usually simply cleaned from oxidation.

Wear of pipes

Coolant may leak from the heating system through the inlet/outlet pipes. This result is usually caused by their wear under the influence of aggressive substances that are components of the liquid, combined with high temperature. The appearance of leaks in the pipes can also be caused by excessive efforts when tightening the clamps during their installation (for example, after replacing leaky old pipes).

The heating system of the VAZ-2114 car includes 4 pipes, half of which are located in the engine compartment, ensuring the passage of antifreeze between the power unit and the heater, and the other two are located in the cabin, ensuring coolant circulation between the radiator and the heater tap. Liquid leakage can occur in two different scenarios. The first involves antifreeze leaking out into the area where the power unit is protected; with the second option, it will flow into the cabin. Signs of a leak in the pipes:

  • decreasing coolant level in the expansion tank;
  • the appearance of a persistent unpleasant odor in the cabin;
  • presence of smudges in the passenger compartment or under the engine protection.

Illumination of the VAZ 2114 stove, replacing light bulbs with LED ones

Sometimes motorists notice that during the operation of the car, such an element as the backlight of the VAZ 2114 stove switch fails - its bulbs first dim, and then completely burn out.

In addition, some drivers are not satisfied with the original lighting at all, and they immediately think about how to change it to LED.

We will talk about how to do this and what is needed for this replacement in today’s article.

Replacing the stove light

Most often, car enthusiasts perform just such a replacement, since the backlight of the VAZ 2114 stove control in its original form is quite dim and often breaks.

In order to change it to a new one, you will need:

  • screwdriver;
  • pliers;
  • knife;
  • new LEDs that will be installed to replace light bulbs.

The entire replacement is done very simply and in just a couple of steps, for this you need:

  1. Disconnect the terminals from the battery.
  2. Disassemble the torpedo at the location of the regulator.
  3. Remove the old lamps (one of them is located directly on the regulator, and the second is on the air flow adjustment levers). This should be done extremely carefully, since the lamps are fragile.
  4. Install new LED lamps.
  5. Perform a performance check (this should be done with the torpedo disassembled).
  6. If the circuit is in good condition and the lamps are on, then reassemble.
  7. Connect the terminals to the battery.

Illumination of the stove with the torpedo removed

LED bulbs should be installed in accordance with their polarity. If you are not exactly sure which of the wires going to the socket is “positive” and which is “negative”, then you can carry out a quick check using a multimeter.

When measuring DC voltage in accordance with the color of the probes (red for positive, black for negative), the screen will simply show voltage (12 v).

Otherwise (if the red probe is applied to the minus, and the black probe to the plus), the voltage on the screen will be shown with a “minus” icon (-12 v).

Redesign of the VAZ 2114 stove lighting

Method No. 2

If you don’t have extra money for a tuning device with diodes, and we’ve already dismantled the torpedo. You can do “luxury tuning” of the backlight of the stove control.

  1. We take 10 centimeters of white LED strip and two pieces of 5 centimeters each, blue and red (the store even sells 5 centimeters each).
  2. We make this design:
  3. We glue pieces of LED strip onto the textolite plate (white on top, red and blue on the bottom) and attach them to self-tapping screws;
  4. You can also substitute bushings to bring them closer to the scale itself (but this is not necessary).
  5. We solder the wires from the tape (can be placed on terminals) to the standard backlight wires and be sure to insulate them with heat shrink or blue electrical tape.
  6. To prevent your eyes from being too blinding at night, we stick a film on the back side (for example: Oracal 8300 073), maybe in two layers.
  7. We collect. It should look impressive.

Causes of failure

There may be several reasons for the malfunction:

  1. The most common problem with a fan not working is a blown fuse. The fuse in the block should be marked F7 (20A). In addition to the stove fan, it is responsible for the cigarette lighter, heated mirrors and glove compartment lighting. If, in addition to the fan, one of the above does not work, then the problem is in the fuse.
  2. Check the functionality of the ignition relay; it may be the cause of the fan not working. Most often, if the relay is damaged, the fan operates once.
  3. Poor fan motor performance. The motor may have worn brushes, oxidized contacts, or it may burn out. In order to clearly determine the problem, you need to dismantle the motor and test it with a multimeter.
  4. Damage to the operating mode switch. It often happens that at the first and second speed the fan does not work, but at the third it works perfectly. This is a problem in the mechanical part of the switch or the resistor that supplies power to the motor at first and second speed needs to be replaced.
  5. Broken fan impeller or slipping on the motor shaft. In this case, it is impossible to repair the VAZ 2114 heater fan; the assembly part needs to be replaced.

Causes of heating tap failure

Of the entire cooling system, the heater valve of the VAZ 2114 is the most vulnerable part. Moreover, problems most often appear with the onset of cold weather. This is where one of the reasons for the failure of the heating tap lies: in the summer we don’t use it, it “sours” and requires repair.

The most common reasons for the failure of the VAZ 2114 heating tap:

  1. Leakage due to depressurization of the housing. This is a serious problem that needs to be fixed as soon as possible. If this is not done, a large leak of the cooling fluid directly into the vehicle interior may soon occur. This leak begins with the flooding of your feet - you can miss this signal, especially when there is a rug under your feet, and if you do not carefully monitor the condition of the working units.
  2. Souring of the locking device. The stove tap, which cannot be closed or opened, indicates that it has “soured.” Don’t rush to the service station, the matter is not urgent, but the problem should be fixed.
  3. Contamination with antifreeze deposits. Just like in a radiator, various deposits accumulate in the tap pipes (as a result of the breakdown of coolant or other type of dirt). So, since the damper regulates and then increases the flow of fluid, it delays it, debris accumulates inside the part, and as a result, jamming and further failure.

The technical condition of the tap, like the entire heating system, depends on the condition of the coolant. There are too many fakes on the market, which have a very negative effect on the operation of the car’s stove.

One of the reasons for the failure of the faucet and the heating system as a whole may be low-quality coolant. Don't take just anything! Make purchases in trusted stores.

But besides the quality of the liquid and materials, there are other factors that influence the rapid failure of the faucet. Therefore, at the end of the article we will give some useful tips that will allow you to extend its life or notice a malfunction in a timely manner so as not to freeze in winter.

Well, for now, let’s pay attention to the choice of the heater valve for the second generation VAZ “Samara” - VAZ 2113, 2114 and 2115 or the first one - 2108 and 2109
