Stove vaz 2114 blowing badly in the legs

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.

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.

The VAZ-2115 is an updated version of the earlier G8, Nine and VAZ-21099. Three and five-door hatchbacks VAZ-2113 and VAZ-2114 have the same characteristics. The device of the interior heater in these cars is the same, so if you are the owner of one of these models, then this article should be interesting for you.

The device of the interior heater VAZ-2115

The stove device is standard here:

  • fan - it directs the flow of air;
  • radiator - it enters heated from the engine for cooling, and the heat generated during this is sent to the passenger compartment;
  • heater tap - when you turn on the stove, the faucet opens and the antifreeze starts to flow into the radiator of the stove;
  • traction dampers - serve to adjust the air supply, as well as to heat the legs and windshield;
  • heater resistor - serves to create additional resistance so that you can select the operation mode of the stove.

An important role is also played by the thermostat and the motor of the stove, which makes the fan spin. If the thermostat sticks, then the liquid will circulate only along the small or large contour of the engine cooling system (and the interior heater refers to it), accordingly, it will not have time to cool and the motor will overheat. If the motor of the stove breaks, the fan blades will stop rotating and warm air will not come from the air ducts.

The system is quite simple and has been used previously on many cars, but over time, various interruptions in work begin. Damage leads to the fact that the cabin is very cold, hot air is not supplied to the glass and it fogs up, or your feet freeze, because there is no blowing, and so on.

The stove does not blow - what is the reason?

If the stove has stopped working, then the reasons, in fact, there may be many:

  • the cylinder head gasket is burnt out and the antifreeze level drops sharply - take urgent measures, otherwise the engine may overheat;
  • jammed thermostat - coolant circulates in a small circuit very quickly and does not have time to cool;
  • the radiator of the heater clogged - in this case, the air enters the cabin hardly;
  • the motor does not work;
  • an air plug has formed - after the engine is turned off, air accumulates in the system and enters the cooling radiator, and after a new engine start, the radiator pump starts pumping this air into the heater radiator;
  • the heater faucet does not open completely - it may become clogged or the draft cable is loose;
  • the radiator pump does not create sufficient pressure in the system, so the air either does not enter the cabin at all, or it does, but with a very low intensity.

Also, the problem of failure of the traction, which opens the flaps for blowing the windshield or legs, can also affect. And another very common problem - the damper does not work correctly, cutting off the flow of cold air from the outside - in this case, you need to adjust the cable that controls its movement.

Symptoms of Malfunction

If you talk to the owners of cars of this family - VAZ-2109-21099 and 2113-2115 - then from them you can hear many flattering words about those workers who assembled the heating system and this very Lada Samara at the factory in Tolyatti.

So, if you recently bought such a machine, turned on the stove and you feel that hot air is coming from the center console, and it is barely warm from the side, lower and upper deflectors, it means that the air ducts and dampers are poorly assembled and there are between joints cracks, warm air simply blows only from the central outlet, and heats the panel itself inside.


Frankly, we also had such a problem at one time. I had to literally disassemble the front panel, and adjust the throttle thrust. The GOR / HOL damper does not close completely, therefore warm air is diffused under the panel. Also, air may not blow directly onto the windshield, which is why it takes a long time to wait until it thaws. The problem is again in the dampers.

There are a number of symptoms that indicate a particular problem:

  • cold air blows at idle - the pump does not work well or the radiator of the stove is clogged;
  • cold nozzles - if the radiator nozzles of the cooling system are cold (lower), this indicates a jammed thermostat and the antifreeze circulates in a closed circuit. Also, this may indicate that the heater faucet does not fully open or clogged;
  • cold air blows from the side deflectors - adjust the dampers and drafts. Some drivers advise choosing a more productive fan from a foreign car.

Heating the interior of Lada Samara is a common problem for owners. Do not forget that everything is connected in the car, so monitor the level of antifreeze, blow out radiators from time to time - how to do this on the website.

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.

    Good afternoon.
    Indeed, the problem lies either in the pump or in the system there is an air congestion. I think that most likely the problem is related to the air congestion.
    First of all, remove the plastic overlay on the engine - unscrew the cover on the engine to fill the oil, and then pull out the entire overlay. It is seated on rubber seals. Having removed this plastic screen, we screw the oil cover back in order to avoid the ingress of dirt into the engine crankcase.
    We find the nozzles for heating the throttle assembly (there are 2 of them) (see the figure below). We remove any tube.
    Next, unscrew the cap of the expansion tank (coolant tank) of the tank, and cover the neck of the tank with a clean rag.
    We begin to blow into the tank with liquid. We blow until all air comes out of the hose and antifreeze flows.
    We quickly put the tube back and tighten it with a clamp so that air does not get there.
    (It is worth noting that, depending on the tube that you took off, the antifreeze may leak both from the tube; and from the fitting from which the tube was lifted)

    The second way to remove air from the cooling system:
    We warm the engine to operating temperature.
    Warming up, turn off the engine.
    The cap of the expansion tank does NOT need to be unscrewed.
    As in the first method, we unscrew the clamp of the coolant pipe on the throttle assembly.
    Having removed a branch pipe of heating of a throttle knot, let out air, and after the antifreeze starts to flow out, immediately put back on the union and fix it well with a collar.
    But be careful and careful! Do not forget that the coolant temperature is approximately 90 degrees.

    There is also a simpler but less effective way to eliminate air congestion:
    1) We call on a steep hill so that the radiator cap becomes the highest point of the cooling system.
    2) Unscrew the cap of the expansion tank and the radiator cap.
    3) Let the machine warm up to operating temperature
    4) Then we gassed several times and in parallel pour coolant into the barrel.
    We do until the bubbles stop appearing.

    Hello!
    In addition to damage to the heater tap and air plug, the thermostat and the water pump may malfunction.
    When replacing the expansion tank, there will be no large loss of antifreeze (if not completely drained), therefore, an air plug is unlikely to occur ...
    Or perhaps the heater valve faucet is simply faulty ...

  • Hello!
    The design of the heater is such that the air temperature is regulated by a damper and a crane through a complex mechanism of levers and cables.
    It happens that the shutter does not open completely, then you need to bend the cable as in the video https://youtu.be/5CfVik72QVg
    The heater radiator must be installed with the pipes up.
    There should be 2 branch pipes in the expansion tank of your car - the upper one is thin under the vapor pipe (3) and the lower one is thick under the antifreeze hose (4). If they are flooded, clean (drill) them with a drill.
    Check the progress of the heater flap, the operation of the heater tap and thermostat, the level of antifreeze, and if the heater does not work, change the radiator. Better on a new sample (with a steam pipe) along with an expansion tank.
