Heating system VAZ-2114: description, features and malfunctions

The car uses a variety of systems andmechanisms. One of them is the salon heating system. VAZ-2114 is also equipped with it. Unlike the air conditioner, the stove is equipped with cars without fail. After all, in the heat, you can open the windows. But in the winter to cope with the cold in the cabin without a stove will not work. What is this element? How is the VAZ-2114 heating system arranged? Scheme, the principle of operation and malfunction - later in this article.

Characteristics and device

The main purpose of this system ismaintaining the optimum temperature in the cabin during the winter season. In addition to comfort, the stove is needed so that glass does not sweat, especially the frontal. To avoid condensation, special nozzles are provided at the top of the panel. However, about everything in order. Below is a diagram of the interior heating system:heating system vases 2114 circuit It is the same for all models of the Lada Samara family, including for VAZ-2114. So, the following elements are included in the system device (decoding of the scheme):

  1. Water-proof flap.
  2. Nozzle for heating the windshield assembly with air ducts.
  3. Side nozzle, designed for heating and ventilation of the passenger compartment.
  4. The central deflector.
  5. The heater assembly with electromotor.
  6. Internal internal ventilation nozzle.
  7. Seal of the stove cock.
  8. The rear branch pipe of the heater VAZ-2114.
  9. Inlet tube of the stove.

Where is the heating system located?VAZ-2114 (injector including) is manned by her in the cabin. The stove is located in the front panel, which is also called a "torpedo". Depending on the modification, the heating and ventilation system VAZ-2114 is interconnected with the air conditioner and evaporator, or goes without it.heating system vases 2114 Also in the design comes the stove cock and the heat exchanger itself. The latter works together with the gearmotor.

How does it work

The operating principle of the system is quite simple.It is based on the transfer of heat from the liquid. So, the heater radiator is connected to the main terminals of the engine cooling system. Inside the heat exchanger is antifreeze or antifreeze. Thus, when the engine is heated, the hot liquid flows along the "large" circle to the radiator of the stove. When the automatic control system is switched on, the heater of the stove is activated. Warm air begins to move along the nozzles. The direction can be different - on the windshield, lateral, in the center of the cabin. One or more deflectors are activated, depending on the position of the lever of the stove.

That is, heat exchange takes place - hot antifreeze cools not only in the main radiator (which stands in front of the engine and is presented in the photo below), but also in the heat exchanger of the heating system.system of heating of salon vaz 2114 Of course, the engine temperature in this casefalls significantly. Therefore, in severe frost motorists close the cavity of the honeycomb of the main radiator, so that the motor is not very cold. The most optimal mode of its operation is 80-90 degrees Celsius. When you turn on the stove, this figure drops immediately by 10-15 percent. However, let's not dwell on the principle of work and consider the main malfunctions of the VAZ-2114 heating system.

It is not possible to adjust the temperature

Often owners of domestic cars (includingVAZ-2114) are faced with the impossibility of setting the air temperature on the control unit. The oven blows equally hot or cold, regardless of the position of the main SAUO lever (in the photo below it is located in the center).heating system vases 2114 injectorIn this case, the specialists statemalfunction of the dampers or malfunction of the control unit itself. A temperature sensor is also diagnosed. It is next to the ceiling light control ceiling. Turn the lever several times. Air heating should change tactilely. If the temperature changes only at the extreme position of the sensor, the element must be replaced.

The oven blows cold

Damper and temperature regulators are extremely rare. Therefore, if the stove is blowing cold all the time, most likely, the gearmotor has failed. This element is presented in the photo below.malfunction of the heating system vases 2114As in this case, the system is being repairedheating VAZ-2114? Injector or carburetor it, does not matter. Due to the complex design, the gearmotor changes entirely. For this it is required to completely disassemble the "frog" of the front panel. Then, using a Phillips screwdriver, three screws are loosened on the stove block, wires are pulled out and the old gearmotor is removed. The new one is connected in the same way. Check up how the system of heating of salon VAZ-2114 works. Air should change its temperature when the lever is moved to the unit from cold to hot mode and vice versa.

The stove bad blows in the legs and side windows

The heating system VAZ-2114 does not differreliability. Over time, the stove ceases to normally heat the legs and side windows. And the trouble is not in the temperature of the air (on the contrary, it can be hot), but in the strength of the flow with which it comes from the nozzles. In this case, it is necessary to refine the air flow channels. To do this, remove the front panel so that there is access to the nozzles.heating and ventilation system vases 2114 Next, a new corrugated hose(from the plant there are just plastic tubes). In addition, we process the joints with the heat-insulating material "Splen". All the cracks between the top and bottom of the panel are also glued to it. Next, you need to modify the damper of the stove, which directs the flow to the desired zone. Often it does not press well against the body. Because of this, a large percentage of hot air is simply lost in the panel and "walks" in the cracks. So, take out the flap and remove the old factory seal of yellow color. We fix all the slots model. Instead of a sponge we glue Bitoplast. It is advisable to apply it in several layers.

Lower nozzles

Next we upgrade the airways for the feet.When parsing the panel, you will see that there is a large gap between the nozzles. We seal it with a corrugated tube. The regular air distributor is taken out, and in its place, too, we fix the corrugation.malfunction of the heating system vases 2114The diameter should be 4 centimeters.Thus, the air will be clearly directed to the feet, without leaks. As for blowing the windshield, it is being modified in a similar way. In addition, the owners fill the excess cavities with mounting foam, in order to eliminate the creaking of the panel during the movement (this problem is pursued by Samara from the first generation). Judging by the reviews, this method works.

Conclusion

So, we found out how the heating system worksVAZ-2114. As you can see, all the malfunctions with it can be fixed by yourself. You do not need to spend a lot of money on this. After minor improvements, the heating system VAZ-2114 will be pleased with reliable and trouble-free operation.
