The stove ("Chevrolet Aveo") does not work: causes and remedies

Heat in the cabin of any car is a pledge not only of comfortable driving, but also of road safety. After all, the temperature in the cabin affects the driver's well-being. Therefore, at the first sign of the fact that inside of the stove does not become warmer, you should start troubleshooting without delay. When winter comes, something to do and look for reasons in a cold car will be reluctant. Completely the same should be done in the summer, because someone is happy to ride in the heat with a full-power stove? The car "Chevrolet Aveo" is very popular among Russian motorists. A good combination of price and quality, as well as the prevalence of spare parts and the relative ease of maintenance make this model quite famous. The most popular in our country (and all over the world) is the T250 generation. But there are no ideal cars. Among various malfunctions there are also problems of heating. And here, too, there are situations when the stove "Chevrolet Aveo T250" does not work. It should be noted that often in the forums there are complaints about the poor operation of the heater. Car enthusiasts do not understand why the stove does not work in Chevrolet Aveo. The reasons here are fairly standard. First, before starting work, you should immediately understand the essence of the heating system of any car. Then it becomes clear why the stove does not work in Chevrolet Aveo. The heating system on modern cars is associated with a cooling system. Tosol enters the radiator of the heater, which is blown by the fan. Heated air is sent to the salon.

Main reasons

So, we do not have the Chevrolet Aveo stove. The reasons can be the following:

- malfunction of the thermostat;

- breakdowns associated with the radiator of the heater;

- incorrect operation of air flow distribution mechanisms;

- malfunction of the heater control unit.

It should be noted that the problems with the heating system in modern cars are almost identical, and the algorithm of actions is the same. Differences appear only in the location of the assemblies and units to be checked.

Preparation for work

All work on troubleshooting the operation of the stove should be carried out only on condition that the engine and its auxiliary units related to the cooling system are in good order. To do this, check the level of antifreeze in the expansion tank. It must be at least minimum, the engine itself should be easily started and warmed up to operating temperature. Often on the last point there are difficulties.

Malfunction of the thermostat

This device regulating the thermal regime of the engine and allowing it to keep its temperature in a narrow range. The stove, like the engine, also works effectively only with a hot engine. Therefore, if the motor does not warm up, the oven blows cold air. The thermostat is diagnosed quite simply. After starting the engine, you need to feel the thick pipes coming from the thermostat to the radiator. As they warm up, they should become hot. If the upper heat immediately, then the thermostat jammed in the open position. In this case, the motor will never warm up to operating temperature, since the antifreeze immediately goes to the radiator, cooling there. Accordingly, the heat exchanger heater will also not become hot. If the hoses remain cold after warming up, this is bad. The antifreeze does not enter the radiator, and the engine overheats. In both cases, the thermostat must be replaced.

Air congestion

Often, when the cooling system is operating, because of its leakage, air gets into it, which has the worst thermal conductivity. Then in "Chevrolet Aveo" the stove does not work or starts to work worse. Often this happens due to the fact that the antifreeze was poured into an empty tank, and the air got into the hoses, not being forced out. The air jam is removed quite simply. It is enough to drive the front wheels to any elevation and turn off the expansion tank cap. After that start the warmed-up motor and rhythmically squeeze and unclamp the branch pipes leading to the tank. Tosol will gurgle, and excess air will come out. From time to time it is necessary to pour the antifreeze. Then wrap the cork and check the operation of the stove. The problem also lies in the leakage of the plug, which should create excessive (but not too much) pressure. Often it can be replaced by several faults.

Problems with the heater radiator

Often the reason why the Chevrolet Aveo does not work is the clogging of the heat exchanger of the heater. It is clogged with dirt, deposits from the cylinder block of the engine, rust and does not warm up properly. Cleaning here is almost useless. Since this requires removing the radiator, it will be more reasonable to replace it.

Malfunctions of the electric motor of the fan

Another common reason why the "Chevrolet Aveo" does not work the stove, are purely electrical malfunctions. Initially, the cold air is pumped by the fan to the radiator of the stove, which then exits into the interior. A special damper directs this air through the radiator or bypassing it. Consequently, if these nodes fail, the air will not blow at all or is sent equally cold at any position of the damper. In the first case, the electric motor of the fan does not work. In the second one, the cable drive of the flap is faulty. If the motor breaks down, search for the problem should begin with the fuse responsible for this circuit. If it is not broken, the wiring is faulty, or the motor itself, which must be replaced or prevented from cleaning. To remove it, you need to dismantle the glove box. The motor is located at the bottom of the heater housing and is held by snaps. To repair the damper drive, you need to remove the lower part of the console.

Faults of the resistor block

The fan motor operates at several speeds. For this, there is a separate block of resistors, which slows down the rotation. If it fails, the motor will operate at separate speeds, or only at maximum speed, directly, without resistance. In this case, the most reasonable is the replacement of the resistance block. As a result, warm air is again blowing from the dampers.

Malfunction of the control unit

The control unit can also malfunction or improperly adjust the temperature in the passenger compartment. Its malfunction is one of the reasons why the stove does not work (Chevrolet Aveo is no exception). Faulty controls on the panel may also malfunction. The control unit itself rarely repairs and is subject to replacement. Another reason for the improper operation of the stove is the failure of the air temperature sensor in the passenger compartment or its closure. In this case, the stove will always "fry" at full or blowing cold air. After all, feedback is through this sensor.

Conclusion

Thus, finding out the reasons why the "Chevrolet Aveo" stove does not work is not such a difficult job. Knowing the device and the principle of the system, as well as representing the sequence of actions, you can confidently deal with this problem yourself.
