The stove on the vaz 2114 is working poorly

If when you turn on the stove, the heating and ventilation system of the VAZ-2114 car, cold air comes from the output nozzles, then a driver who is well versed in technology will immediately realize that there are some problems with heatsink radiator   or with   damper, which changes the direction of air flow. But there will be several reasons for their emergency work.

Maybe, heater tap did not open. It is driven by a cable drive. If this cable is weakened, then when moving the crank opening handle to the “Open” position, the crane will either not open at all, or will open slightly. You can check the operation of the heater radiator on a warm engine, without turning on the fan. To do this, you will have to feel the supply and exhaust hoses to the faucet of the stove. They are well accessible under the hood of the car. From the temperature difference, you can determine whether the coolant is supplied to the radiator.

The culprit of the cold radiator on the VAZ 2114 may be the crane itselfwhose damper has soured over the summer period. In this case, when you try to open the valve, the valve may break off from the drive roller. The stove radiator will not be warm enough even with a low level of coolant in the engine cooling system, as well as with a faulty thermostat or the appearance of an air plug.

The flow of air entering the interior of the VAZ-2114 is controlled by damper. It also has a cable drive and the cause of its incomplete opening will be the lengthening of the cable, because in the process it is gradually stretched. In this case, most of the cold air flow will go directly to the cabin, and not through the radiator. Because the air along this path is much easier to move.

Knowing the principle of operation of the stove, it is not so difficult to guess its malfunctions. But in order to eliminate them, you will have to spend a lot of time, since the stove is located behind the front panel of the cabin and it is impossible to eliminate malfunctions without at least partial disassembly.

VAZ-2114 is the second generation of the legendary Lada Samara. The car got a new look, but did not get rid of old problems. In particular, these are regular malfunctions of the cabin heater. It often happens that on the VAZ-2114 on the sides and on the windshield. Naturally, this problem should be dealt with urgently before the onset of the first cold weather. So, let's look at why the stove blows cold air on the VAZ-2114 and how to solve this problem.

Thermostat

This is a kind of valve that makes the coolant move in a large or small circle. It serves to quickly warm up the engine. But also this detail is connected with the cabin heater. Until the thermostat opens to the "big circle", the stove will be cold. This problem is observed not only at idle. On the VAZ-2114, the stove blows cold air due to unheated coolant. Along with this, the motor itself suffers, since it is not in its temperature regime. The most optimal indicator is 80-90 degrees. If less, then the element opens ahead of time or jammed at all. In the latter case, it is only subject to replacement. Fortunately, a new thermostat on Samara is inexpensive - about 300 rubles.

System air

This is the second reason why the stove blows cold air on the VAZ-2114. Also, the motor itself may overheat due to this problem. Where can air get in the system? The reason is an unauthorized "leak" that may occur during repair operations of the system. So, very often air enters when replacing the same thermostat or stove faucet. How to check for its presence in the system? First, pay attention to the temperature sensor. But it does not always give an accurate result. The machine can work in normal mode, but at the same time there will be air in the radiator of the stove. How to identify it? It is enough to touch the rubber pipes that go to the heat exchanger. On the VAZ-2114 they are on the right, from the passenger side. In total, there are two nozzles in the stove system.
If air is felt during their compression, then it must be removed.

How to clean the system from cork?

The solution to the problem is quite simple. You should call on a hill in front of the machine. The greater the degree of rise, the better. Next, on the working motor, we unscrew the plug from the expansion tank and wait until all the air leaves the system. According to the laws of physics, air is lighter than liquid and tends to go up. So we will create the most favorable conditions for this. Three to five minutes of engine operation is enough to completely remove the plug from the system. Periodically, it is necessary to gas up to 2-3 thousand revolutions in order to create more pressure for the coolant (the stronger the crankshaft rotates, the more often the pump rotates). It is also recommended to compress and unclench the air inlet - so we will accelerate the process of oxygen release to the outside. But be careful - the temperature can reach 90 degrees. For safety reasons, wear gloves.

Damper

This is another reason why on VAZ-2114 the stove blows cold air into its legs and not only. The damper may be loose for several reasons. So, the control lever can fly off or the foam can peel off. In the latter case, you need to stick a new one. Preferably on a quality glue.

On the VAZ-2114, the stove blows cold air on its sides

You can see the photo of the side flaps below.

Owners of VAZ-2114 cars often encounter a similar problem: warm air goes to the window and legs, and cold air is on the sides. What is the reason? The reason is the ill-conceived location of the stove body. This problem was observed even in the Soviet "eights". So, the nozzles of the side air ducts are located below the damper itself. And as soon as the latter opens up, cold air immediately enters the damper.

The side airflow control cable is located at the driver's feet, on the left side. If the stove blows cold air on the sides of the VAZ-2114, you should tighten the cable. There are two ways to do this:

• Using pliers, without dismantling the shutter. Having approached the problem place, we are pressing the element several tens of degrees.
• With the help of pliers. This is a more efficient option. To do this, remove the torso from the flap lever and tighten it a little. For convenience, it is recommended to partially disassemble the console. This way you can control the tightness of the shutters in place.

Lever arm

If the stove blows cold air on the VAZ-2114 even after tightening the cable, it is worth examining the condition of the lever itself, which opens the damper. Despite the thickness of the metal, it can crack. In this case, the damper wedges in one place. Usually it is slightly ajar. As a result, air from there blows a completely different temperature. The way out of the situation is to buy a new lever.

But often it is sold complete with a deflector. After replacing it, the stove works as expected. Hot air blows from all sides - to the feet, to the windshield, to the center and sides. Least of all warps the damper itself. There are few reasons for its deformation (banal use of the stove to its maximum potential), but this problem should not be excluded from the list.

Conclusion

So, we found out for what reasons the stove blows cold air on the VAZ-2114. As you can see, the problems can be different. But before you buy new parts, you need to accurately determine the essence of the problem. Perhaps the culprit is the air congestion. In the case of a cable, it is not necessary to change it entirely. The above is a way to resume its functionality with a simple lift. But no matter what the reason, in any case, it can be solved with your own hands at minimal expense.

The domestic auto industry is full of “automobile diseases”, but it’s worth learning about the way to solve these “diseases”, as things get a little better. Basically, these are some little things that make up the whole idea of \u200b\u200bthe car as a whole.

This is exactly the case: the most typical disease of the VAZ-2114 is the stove, which also stops the windshield. And first of all, the owners of the VAZ-2114 are looking for a reason under the hood (they close the radiator, “cover” the engine with their grandfather sweatshirt, change the thermostat, they even look for a solution to the problem of cold air from the stove to replace the coolant), and the reason may be in a completely different place.

Diagnostics

The most important thing in the repair is a correctly conducted diagnosis, identifying the primary cause of the malfunction. We will start with the engine compartment. Check the coolant level. We start the engine and warm up to operating temperature. If the engine is gaining temperature and the branch pipe to the thermostat is warm, and after it is cold, this means that the thermostat is working and the problem is not in the engine cooling system, but in.

Reason # 1

The control cable is loose or slipped.

Decision

1. Disassemble the driver side side panel.
2. On top there is a flap control lever. A cable comes from the control lever on the center console (cold - hot).
3. Visually inspect the cable itself and the damper control lever.
4. If everything is whole, then he just stretched out.
5. Unscrew the cable bracket and remove it from the lever.
6. Take the eye of the cable with pliers and turn it clockwise to make the cable shorter.
7. Putting it all in reverse order.
8. Without assembling the side panel, we check.

In most cases, the cause of the malfunction is precisely in the cable, if the problem has not been solved and then we understand further.

Reason number 2

Ducts and dampers are poorly assembled and there are gaps between the joints. The air ducts themselves can break heavily in places of bends and not allow air to pass through, then warm air simply blows only from the central deflectors and heats the panel itself inside.

Decision

1. Inspect the ducts. If there are cracks and kinks, it is better to replace the duct with a new one.
2.   self-adhesive foam rubber.

Sometimes owners of VAZ-2114 cars have to deal with the problem of an idle stove. In particular, such malfunctions cause problems in the winter period, since the car interior is not just unbearable cold, but the windshield tends to become covered with a thin crust of ice, which greatly obscures the view. Therefore, if suddenly the stove stopped working in the VAZ-2114, you should immediately find the cause of the malfunction.

Such problems can occur for a variety of reasons, ranging from wear on the cooling system to problems with the wiring. This article will examine in detail all the possible causes of a stove malfunction, thanks to which it will be possible to find a solution to this problem.

It should be noted that the symptoms of a stove malfunction can be divided into two types:

1. Cold air is blowing from the stove. Occasionally barely warm.
2. The stove does not turn on at all or does not work in some separate modes.

Malfunctions of the VAZ-2114 cooling system

If the thermostat does not work in the car, in a large circle the coolant that is available in the system is constantly chased. As a result, it turns out that the liquid does not have time to heat up, so cold or slightly warm air blows from the stove. In order to solve this problem, it is enough just to repair or replace the thermostat.

Another reason may be the banal air plug formed in the thermostat. In order to eliminate this problem, you need to throw off the pipe going into the heater, and then add antifreeze to the very top. It should be noted that in this case, the liquid level in the system should not be lower than the maximum mark, or even a whole centimeter above it. And all because if the system does not have enough liquid, the stove blows cold air.

If, at idle, the stove blows with cold air, the problem may be hidden in the pump, since it is not able to provide normal circulation in the coolant system. In this case, the pump must be replaced.

Clogged radiator stove in the VAZ-2114

If the cause of the cold air blowing from the stove is a clogged radiator, the only way to eliminate this problem is to dismantle the radiator, as well as its subsequent purge.

Most often, after this the stove starts to work, like a new one.

Damage to the faucet of the stove

Quite often, the stove of a VAZ-2114 car blows with cold air due to a malfunction of the faucet. In order to get rid of this problem, you should tighten the cable, which can easily be reached from the pedal assembly. At hand, you must have pliers, which, in fact, stretches the cable.

In the event that, having done all of the above, the faucet of the stove still does not open, there are only two reasons:

• crane soured;
• crane needs replacement.

By the way, this procedure should be carried out very carefully, since it is easy to disrupt the tap, as a result of which fluid will flow directly into the passenger compartment.

The malfunction of the faucet is indicated by the cold air that blows from the car's stove while it is on for heating. Another reason for replacing the tap is leaking.

If you decide to replace the faucet yourself, we present to your attention the sequence of actions:

• unscrew drain plugs located on the engine block;
• drain all coolant that is in the system;
• strip the studs on the faucet with an iron brush;
• moisten them with a WD-40. Thanks to this action, loosening is much easier;
• unfasten the clamps on the nozzles and drain the remaining fluid;
• in the passenger compartment, unscrew the side trim, release the clamps on the pipes that are directed into the heater radiator;
• unscrew the nuts under the machine holding the crane;
• pull out the crane through the cabin;
• disconnect the cable leading to it;
• connect it to a new tap;
• check if all parts are assembled correctly;
• start the assembly process in reverse order.

Relays and Fuses

A blown fuse is one of the most common stove malfunctions in the VAZ-2114. This reason is extremely simple, because it can be eliminated by every person who does not have the slightest idea in the structure of the car. However, this reason is also very unpleasant at the same time, since it is firstly necessary to establish the reason why the fuse has blown, and secondly, it is not so easy. Usually a blown fuse indicates a malfunction in the car wiring.

The problem with the switches

In order to check the serviceability of the switches of the stove, you need to get the simplest light bulb, with a capacity of 12 volts, with two wires. Next, remove the central part of the dashboard and perform the following actions:

• turn on the ignition of the car;
• short-circuit the wire to negative ground from the bulb;
• the positive contact is alternately connected to the outputs 1-2-3 on the additional resistor.

If during this procedure the lamp lights up, this indicates that the switch is working. But in case the bulb did not light up, most likely, the fuse was blown or the circuit broke.

What to do if the cold air of stove 2114 comes in? This question often arises among motorists. All parts in any car perform a special function specially designed for it, and when something becomes worthless, the car owner has to figure out what caused the breakdown.

What to do if in the stove VAZ 2114 cold air?

The cold air of stove 2114 creates many problems. VAZ is a car beloved by many, but it also often has problems.

The task of the stove in the interior of any car is to create a warm climate. Car stove - the device is not very complicated, and the engine supplies heat. The pump sends antifreeze through heating and cooling systems, antifreeze in the hot state enters the furnace radiator, and the fan at this time passes the already heated air. Therefore, it becomes warm in the cabin. Antifreeze then returns to the engine.

If in the VAZ 2114 the stove gives cold air when the mode is on, an urgent inspection of the entire machine is necessary, otherwise, it would seem, a small breakdown can lead to a serious repair.

Most often, the reason lies in the laying of the head cylinder block.

If it was pierced, then even by eye you can determine whether this is so. This will become clear if you make sure that in the expansion tank:

• air bubbles come in;
• an excessive amount of antifreeze comes in, and it does not decrease (this is the reason for instant engine heating even at idle).

A gasket hole indicates that the thermostat needs to be checked, and there is a possibility that the operation of a large cooling circle is disrupted.

Most often, the gasket is broken, burnt in place between the cylinder and the cooling, then:

• antifreeze can get into the camera;
• gases to the cooling system.

If the cooled air blows, there is a fear that during the movement the hoses of the heating system could not withstand the load. When the engine got too hot, they burst, and after them the cylinder head gasket.

A pump malfunction can also cause the stove to be supplied with air far from warm. But this is not dangerous. Such a breakdown entails a malfunction in the cylinder head.

Because of this, the engine can overheat so much that the engine will not withstand, and it will face major repairs.

Dusty, dirty roads complement vehicle breakdowns. The radiator suffers first of all. It may be partially or even completely blocked from the ingress of road dust. The air, which according to all the rules must pass through the grill, will in this case look for better ways for itself and blow around the edges of the radiator, and the stove, accordingly, will not please the driver with warm air.

How to fix a stove if it blows cold air?

The formed air in the stove itself is unlikely to disappear - the radiator contains narrow tubes, and the antifreeze does not have so much pressure as to eliminate the resulting jam.

You can do this in the following way:

• warm up the engine, but only to the point where you can manually perform repair work without burning your hands - serious injuries can be obtained;
• loosen the clamp located on the hose connected to the stove;
• carefully remove it from the tube, but only until a small gap appears, which allows you to get rid of the resulting plug.

A faulty faucet can also interfere with heating. The reason is that it was time to replace him long ago because he had broken or clogged. To make sure exactly what the reason lies in it - cold air enters the cabin instead of warm air - check the inlet hose: it comes from the radiator of the stove.

In the event of a malfunction, it heats up, and the output remains cold. If the tap cannot be opened manually, it is necessary to install a new one.

If it turns out that the damper is still in perfect order, there is a risk that the radiator is clogged with scale. This suggests that it will have to be replaced.

If the faucet does not open, it means that there is a possibility that there is a problem with the cable drive, since the operation of the faucet depends on this type of drive. The weakened cable, which lengthens over time, wears out, will not allow the faucet to open even in the “open” position, or it will open only slightly.

You should check how the radiator works, warming up the engine, but you do not need to turn on the fan. At the same time, the temperature of the hoses must be checked.

Having figured out how the stove works, you can understand the reasons for its breakdown, but it will take time and certain skills to fix it, since the stove itself is located behind the front panel of the passenger compartment. This means that at least partially, but disassembly can not be avoided.
