ladaservice.info/vaz-2113…/trosiki-pechki-vaz-2114/ used the article Most cases of stove malfunctions are associated with just one reason and this is the VAZ 2114 stove cable. The fact is that over time the tension of the cable weakens.
This occurs as a result of its constant tension, weakening when moving the lever for adjusting the heating mode (cold and hot). There are also cases when the cable completely flies off the stove tap. As a result, the stove valve does not open completely, thereby you do not receive significant portions of hot air from the heating system. What to do? To change or not to change? Here are the most common questions from car enthusiasts. Let's answer this: before replacing anything, you should find the cause of the malfunction and try to eliminate it. Diagnostics of the operation of the VAZ 2114 stove cables In order to inspect the valve cable of the VAZ 2114 stove, it is necessary to dismantle the side panel trim on the driver's side (to the right of the gas pedal). Further details:

Start and warm up the car engine thoroughly. Unscrew the three side trim mounting bolts. Turn your gaze towards the heater valve. Check to see if the cable has come loose from the faucet. Move the heater lever on the instrument panel to maximum heating mode. Pull the cable towards you and hold it in this position. Check whether hot air is coming from the deflectors. Now that the source of the problem has been identified. It is required to fix, give constant tension and thereby ensure good operation and correct throughput.

One of the options for increasing the tension is a method in which a part (0.5-1 centimeter) of the cable is bent at the point of direct connection to the heater lever. To do this you will need:

Remove the second trim, only from the passenger seat side. Take pliers and pull the cable towards you (at this moment, the temperature switch should be at maximum heating mode). Bend the additional amount of cable formed (its amount is selected experimentally, and in each specific case it differs and, as a rule, amounts to 0.5 centimeters). We hook it up to the temperature switch of the stove. Attention! To avoid damage, perform all tension-related actions carefully and do not use excessive force. If you overdo it with tension, you can damage the system and the functionality of the heating system.

Replacing an additional resistor for the VAZ 2114 heater

To adjust the operating speed of the stove on the VAZ 2114, an additional resistor is provided. The resistor has two spirals with a resistance of 0.82 and 0.23 Ohms. When the heater is turned on to the first mode, current flows through two spirals. When the second speed is turned on, the current will flow through one spiral with a resistance of 0.23 Ohm. And when the third mode is turned on, the current will flow past the resistor. An additional resistor is located under the gas pedal.

The resistor, as a rule, does not require repair. Often it breaks as a result of burnt contacts. In this case, it is necessary to clean the contacts. The pad may also melt.

First remove the left instrument panel console trim.
Disconnect the wires from the additional resistor.
Unscrew the screw securing the additional resistor.
Remove the additional resistor.
Inspect the coils for integrity.
Using a multimeter, check the resistor for breaks.
If there are breaks, replace the resistor.
Installing the resistor is done in the reverse order.

Problematic cables

In total, problems can arise with two types of cables:

It is these elements that VAZ-2114 car owners have to deal with when the heater stops functioning effectively. It is recommended to first check other elements of the system for serviceability and operability, so as not to carry out unnecessary disassembly, assembly and adjustment work in vain.

Adjustment

Hot antifreeze for the heating system on the VAZ-2114 model is supplied mechanically, for which appropriate cables are used. Over time, they become dirty and stretched out. The moment of weakening of the fastening element is also taken into account. Because of this, the stove begins to function incorrectly. When the cable is loose or stretched, moving the heater tap slider on the panel does not make it possible to fully open or close it.

The first thing you can do in such a situation is to try to tighten the crane cable. For adjustment you need:

Important! Do not start working on a hot engine immediately after entering the garage. And it is also recommended to first remove the ground from the battery, since you will be working in the wiring area.

The damper cable is adjusted in approximately the same way:

Important! In some cases, adjustment only gives a temporary effect. If the wear is severe, such operations may not produce results, so the only way out of the situation will be a full replacement.

Replacement

You can change the elements yourself, but it is recommended to allocate several hours of your time for this in advance.

Important! After the measures taken, be sure to check how correctly the stove is working and whether everything was done in accordance with the instructions. If the heater is not working properly, double-check that it was replaced correctly. If the problem does not go away, you will have to look for the cause in other nodes.

The stove on VAZ-2114 cars is considered quite capricious. But this mainly applies to conditions under which the heater has to operate under maximum loads. VAZ-2114 car owners living in regions with fairly warm winters rarely complain about the stove. They have to use it less often, and therefore it breaks down less often.

Location of cables for the VAZ 2114 stove

On the driver's side, remove the panel cover. A little higher under the steering wheel, not immediately noticeable, the cable is attached to the heater tap. It needs to be shortened. I shortened it literally by 0.5 cm, making one more turn.

By pulling cable No. 20 (damper adjustment), I ensured that hot air entered all the side air ducts. After some time, having adjusted the length of cable No. 21 (adjusting the heater tap), I received hot air already at an engine temperature of up to 60 degrees.

Usually, newbies who have driven (or just started driving) a VAZ 2114 for the first winter season turn to car service centers with this question. The fact is that the car has such an unpleasant feature (here we say hello to the engineers of the Volga Automobile Plant), such as a problem with the operation of the stove. Moreover, for some it appeared in the very first winter after purchasing a new car at a car dealership.

How to adjust the dampers on the VAZ-2114 stove

The stove installed on the VAZ-2114 copes with its functions relatively well. But she has weaknesses. One of them is dampers. In a car, the position of the dampers is adjusted by three cables. Over time, they lose their properties, stretch or loosen their tension. If the heating system is not adjusted, then hot air will only flow through the central air ducts. And the passenger and windshield will remain without heat and heating. In this case, it is important to figure out how to close the heater dampers on a VAZ-2114 and adjust them.

The first “jamb”: the stove tap

The first problem area of the VAZ 2114 is the valve at the antifreeze inlet into the stove. On the one hand, its undoubted advantage is that if you accidentally break off the fitting on which the pipe is placed, it is enough to replace the tap. For example, on most foreign cars produced in the 90s, these fittings are an integral part of the heater radiator. If they are broken during repairs, you will have to replace the entire radiator. But on the other hand, due to this design, the quality of coolant circulation is much worse. And that means comfort from being in the cabin.

In addition, the supply of hot antifreeze for the stove is controlled mechanically on the VAZ 2114 using a cable. And this cable becomes dirty and “pulled out”. The fastening of this cable itself may weaken over time. As a result, the stove will not work properly.

Usually, if problems arise with cold air from the stove, it is recommended to tighten the cable.

Adjusting the heater tap cable

The problem arises due to the general unreliability of the mechanical cable system for controlling the interior heating controls on the VAZ 2114. We have already talked about this. Loosening or pulling the cable over time leads to the fact that the stove tap no longer closes (opens) completely when moving the slider on the control panel. To solve this problem, you need:

This basically works. But it may happen that you have to tighten it regularly. Often the problem returns periodically. The fundamental measure to solve it is the following method: removing the tap from the system.

Signs of malfunction of the VAZ 2114 heater valve

Most often, a malfunction occurs in the cold season, when the interior heater is used at full capacity. Breakdowns are also possible in warm weather. Constant use of the temperature regulator in the cabin leads to rapid wear of the plastic parts of the faucet. We list the main symptoms of a malfunction of this element:

The appearance of a greasy coating on the surface of the windshield. This is typical when there is antifreeze leaking from the valve body. In addition to the fact that in the event of such a breakdown, the warm airflow ceases to function normally, antifreeze vapors have a negative impact on human health;
Stopping the supply of warm air indicates that the regulator is jammed inside the faucet;
The main sign of a malfunction is the appearance of a coolant leak under the carpet on the driver's side. It is recommended to check this area for leaks regularly.

In addition to stopping the supply of warm air, a broken faucet leads to a constant leak of antifreeze. This increases the risk of reducing the coolant level to a minimum, which is very dangerous for the engine. Sooner or later, replacing the heater tap on a VAZ 2114 is necessary on any car of this model. Even timely maintenance of the heating system does not guarantee that this unit will not fail. It's all due to a design miscalculation by the engineers. Making a faucet that constantly contains hot liquid from low-quality plastic is a clear miscalculation. Minimal deformation of the valve body leads to antifreeze seeping into the driver’s feet. Also, owners of model 2114 complain about the lack of o-rings and rubber gaskets in the design of the regulator. Instructions on how to change the stove tap will be presented below. First, let's look at the necessary list of tools that will come in handy when replacing an element with your own hands.

Problematic cables

In total, problems can arise with two types of cables:

Adjustment

The first thing you can do in such a situation is to try to tighten the crane cable. For adjustment you need:

The damper cable is adjusted in approximately the same way:

Replacement

You can change the elements yourself, but it is recommended to allocate several hours of your time for this in advance.

The second “jamb”: dampers

Another problem with the VAZ 2114 stove is the operation of the dampers. In the car, their position is regulated by three more cables. They also tend to become loose and malfunction over time. An indicator of a violation of their adjustment is the fact that hot air comes only from the central air duct, while cold air goes to the passenger seats and to the front window heater.

Adjustment of these cables is carried out similarly to the cable of the stove faucet. When the slider is moved to the extreme right, the dampers should be fully open.

If you plan to adjust the heater while replacing the radiator, you should also pay attention to the condition of the dampers themselves. If they are not airtight, they should be glued with foam rubber or any other insulation. Any leaks lead to the dilution of the hot air flow with cold air and, as a result, to a deterioration in the operation of the stove.

Modification of the left deflector

The left deflector (driver's) is located farthest from the hot air entry point. As a result, all losses affect him more than anything else. It also happens that there is warm air everywhere except it. Naturally, the driver will not like this much, especially if he usually drives alone in the car.

To improve the heating system and provide the driver's air duct with a sufficient flow of warm air, an additional fan is installed in it.

A computer processor cooling fan is ideal for this purpose (it can be bought at any computer store, it costs about 500 rubles). They come in different sizes and power, choose the right one based on the supply on the market. Or if there is an old computer somewhere in the garage, take it from there - it will do.

By performing all these manipulations, you can achieve restoration or even significant improvement in the operation of the stove. If your work involves constantly moving around the city by car, these measures are simply mandatory.

Diagnosis of heating system faults

Heating system malfunctions are accompanied by the following symptoms:

Why the stove does not work or does not heat the air

If the stove fails, it either does not work at all, or it works but does not heat the air. In the first case, first check the fan wiring, starting with fuse F7. If the fuse is blown, replace it. Then they check the relay, which may not turn on the first time or only when the engine is warm. In this case, the relay is replaced with a new one.

Then the serviceability of the electric motor is assessed. To do this, power is directly supplied to its contacts from the battery. If the electric motor starts to operate at maximum speed, then it is in good condition. Otherwise, it will need to be repaired or replaced.

The intensity of the air flow is adjusted using a resistor having two spirals with resistances of 0.82 Ohm and 0.23 Ohm. In the first mode, the current flows through both spirals, in the second - only through a spiral with a resistance of 0.23 Ohms, in the third - bypassing the spirals, that is, without resistance at all. If the resistor is faulty, the fan will only operate in the third mode at maximum speed (handle in the extreme right position). The problem is solved by replacing the resistor, which is located on the driver's side above the accelerator pedal.

If the resistor is faulty, the heater fan will only be able to operate at maximum speed.

If cold air enters the cabin, this may be due to:

If the stove is clogged, warm air will stop flowing into the cabin.

Heater dampers don't work

The distribution of air flows throughout the cabin is carried out by dampers, which, in turn, are controlled using cables. When these cables fail, problems arise with directing the air flow to the windshield or to the foot area. In addition, the damper that blocks the flow of air from the street begins to work incorrectly. In this case, adjustment of the damper drives is required.

Such situations can arise even on a new car. Slightly warm air begins to flow from the lower, upper and side deflectors, and hot air begins to flow from the center console. This is due to the poor build quality. There are gaps between the joints of the air ducts and the dampers, which leads to warm air entering only from the center console and heating the panel from the inside.

The drive cable is always taut. Therefore, over time it bends, breaks off or stretches. In this case, it is necessary to adjust the damper drive, which is performed in the following order:

Why is antifreeze leaking from the stove?

A coolant leak in the heating system can occur from:

If a coolant leak occurs from the radiator, it is usually replaced with a new one. Repairs to restore tightness are usually complex and labor-intensive. In addition, if the radiator has been in use for a long time, its tubes become clogged with deposits and dirt, and, as a result, heat transfer decreases.

The valve opens and closes the coolant supply to the radiator, thereby regulating the heat in the cabin. Over time, it may begin to leak, as evidenced by the characteristic smell of antifreeze in the cabin, a puddle on the floor on the passenger side and a decrease in the coolant level in the expansion tank. The faucet cannot be repaired and in such cases is replaced entirely.

If the heater radiator starts to leak, it is usually replaced with a new one.

The cause of coolant leakage from the pipes is usually their wear - the rubber ages and cracks over time. When diagnosing a problem, you need to wipe the suspected leak areas with a rag and observe the outlet and inlet pipes on a warm engine. Worn hoses are always replaced with new ones.

The stove makes a hum, whistle, murmur

The cause of uncharacteristic sounds (whistle, hum, murmur, etc.) from the heater is usually a faulty electric motor. Lack of lubrication, contamination, wear of bearings and bushings - all this leads to the fact that the motor begins to whistle. It is removed, disassembled and cleaned, and the rubbing elements are lubricated. If the bearings are heavily worn, the motor will not make a whistle, but a hum. In such a situation, lubricant may not help, and the electric motor will need to be replaced.

Steam is coming from the stove

Sometimes steam starts coming out of the stove. The reason for this is a leak in the heater core. The leaking coolant hits the hot radiator housing and begins to quickly evaporate, and the smell of antifreeze appears in the cabin. To fix the problem, you will need to disassemble the stove and replace the heat exchanger.

Sometimes white steam comes from under the hood and enters the cabin. This happens when antifreeze gets on the hot manifold or exhaust system pants. In this case, you will need to find the location of the leak and fix it. The most common cause is damaged pipes.

The principle of operation of the heater cables on the VAZ 2114

The operation of a car's heating system is to transfer and redirect the heat that is released as a result of engine operation. Heat is removed by the cooling system and supplied, among other things, to the heater radiator. Then, when the switch is turned on (turned on), the heating system starts a motor that blows out hot air and passes it through the car panel deflectors. Air redirection to a particular area is carried out directly by the driver by switching the airflow positions.

Most cases of stove malfunctions are associated with just one reason and this is the VAZ 2114 stove cable. The fact is that over time the tension of the cable weakens. This occurs as a result of its constant tension, weakening when moving the lever for adjusting the heating mode (cold and hot). There are also cases when the cable completely flies off the stove tap. As a result, the stove valve does not open completely, thereby you do not receive significant portions of hot air from the heating system.

What to do? To change or not to change? Here are the most common questions from car enthusiasts. Let's answer this: before replacing anything, you should find the cause of the malfunction and try to eliminate it.

How to adjust the heater dampers on a VAZ-2115

Many VAZ-2115 owners have problems with uneven heating of the interior. Namely, when cold flows blow onto the windshield from the side air ducts, and hot flows from the air ducts located in the center of the dashboard. This becomes especially noticeable when the temperature of the heating system decreases. You can solve this problem yourself quite simply. We will tell you how to adjust the heater dampers on a VAZ-2115 in this article.

Adjustment process (1 method)

Remove the side cover of the dashboard on the left side. Near the gas pedal you will see a damper rod cable and a cable fastening clamp, which you need to unfasten and then pull the cable down. Fasten the clamp and place the damper control levers: the left one to the right all the way, and the right one to the left all the way. In this case, the lever controlling the heater tap must be turned all the way to the right. After that, a warm stream will blow from the side holes onto the windshield, and not cold as before. This method of adjustment, unfortunately, does not give 100% results; you can adjust the interior heating even better using the second method.

Adjusting the damper (2nd method)

After moving the heater dampers to the left, after a while, instead of a warm flow, cold air begins to blow from the side holes. This is due to the fact that the lever controls not only the heater tap, but also the damper, which opens access to the cold outside and it, bypassing the heater, penetrates into the car interior. To fix this, disconnect the cable that affects the heater control damper lever on the VAZ-2115:

After this procedure, warm air will flow from all holes, and its temperature will change when adjusted from hot to cold.

Other reasons for the heating system to malfunction

It happens that the VAZ-2115 stove has been adjusted, but it still does not heat well, the air flow coming out of it is a little warm. In this case, you need to perform another simple procedure to clean the hoses. For this:

The solutions presented in the article are very simple, but effective. After the procedures performed, your car will no longer be cold in winter, everything will work as it should. Moreover, you will not need any cash costs or special tools, and all adjustment actions will not take much time.

Diagnostics of the operation of the VAZ 2114 stove cables

In order to inspect the valve cable of the VAZ 2114 stove, you need to dismantle the side panel trim on the driver's side (to the right of the gas pedal). Further details:

Now that the source of the problem has been identified. It is required to fix, give constant tension and thereby ensure good operation and correct throughput.

One of the options for increasing the tension is a method in which a part (0.5-1 centimeter) of the cable is bent at the point of direct connection to the heater lever. To do this you will need:

Attention! To avoid damage, perform all tension-related actions carefully and do not use excessive force. If you overdo it with tension, you can damage the system and the functionality of the heating system.

Step-by-step replacement of the VAZ-2114 stove

For those for whom this method is not suitable, you can completely remove the stove and adjust it. This is done in stages.

Before you remove the heater (1), do not forget to disconnect the ground wire, otherwise the battery will play a trick on you. At the same time, drain the coolant from the system.

Now remove the instrument panel, as well as the floor tunnel lining. Now carefully disconnect the air duct (under No. 19) to heat the interior.

Start a new round of work:

Carry out the same manipulations with the electrical wires from the resistor (No. 18), the electric motor (No. 2) of the fan, the inlet (No. 12) and outlet (No. 13) faucet hoses.

Sequentially unscrew the 2 nuts securing the faucet directly to the front panel.
Remove the seal from the faucet pipes.
It's time to unscrew the 4 nuts securing the stove to the body.
You can easily remove the heater of your vase with control assembly.
Once you finish the adjustment process, carry out the installation in strict reverse order.

Replacing heater cables on a VAZ 2114

Sometimes situations occur when, for one reason or another, the product becomes bent or even breaks off. Such cases require removing the device and replacing it with a new one. Recommendations for analysis are as follows:

There are a lot of different models on the auto goods market that differ in length, thickness, various types, and shapes of both ends. In order not to make a mistake when purchasing a new product, we advise you to take it with you to the store. Usually cables are sold in one set of several pieces at once.

Adjusting the heater damper VAZ 2114

Remove the bracket holding the cable sheath to the heater body.
On the left there is a yellow lever, which is made of galvanized steel.
Pull this lever towards you, towards the car interior. In this position, it is considered open to the maximum.
Pull the cable and adjust its length. The correct setting is when, in the right position of the long lever located on the lever block, the adjustable device is in the maximum open position.
After adjusting the position of the cable, secure it securely.

Repair of VAZ 2114 stove: radiator (heater) and other components

The additional stove on the VAZ-2114 is most often of interest to motorists living in the northern regions of the country. However, recently there has been a trend that even cars “living” in the middle zone are equipped with it. As a rule, this type of car owner includes those who want to drive with greater comfort in a fully warmed-up car, and those who do not want to waste time optimizing the operation of a standard device.

The example will consider options for devices that will directly interact with the cooling system of the power unit. Maximizing the benefit of the device will be the built-in electric fan, through which the hot air flow is distributed throughout the vehicle interior. It is worth noting that such a device can be purchased at a car dealership or, if you have free time, you can make it yourself.

The VAZ 2114 stove does not heat well

Oh, those stoves! Let's try to figure it out.

Situation: The car owner’s interior is poorly heated by the stove, although warm air is supplied, and the engine temperature remains within 90 degrees. According to external signs, the radiator of the heating system is also hot and the pipes are in normal condition.

Question: What should I do?

Answer: Unscrew the side of the passenger torpedo (the brains) yourself and inspect in the area of the engine shield there are 2 hoses that go to the heater. Feel how hot they are. If there is no heat there, then they are clogged. Clean it and everything will be as it should! Now check the engine using the sensor or on-board indicator.
