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

Warmly in the cabin of any car - no guaranteeonly a comfortable ride, but also road safety. After all, the temperature in the cabin affects the health of the driver. Therefore, at the first signs that the inside does not get warmer when the stove is working, it is necessary, without delay, to begin the search for a malfunction. When winter comes, doing something and looking for reasons in a cold car will be reluctant. It should be done the same way in the summer, because who likes to ride in the heat with a stove working at full capacity? 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 throughoutworld) is the generation of T250. But there are no perfect cars. Among the various faults are problems of heating. And here, too, there are situations when the Chevrolet Aveo T250 stove does not work. It should be noted that often on the forums there are complaints about the poor performance of the heater. Motorists do not understand why the stove does not work in the Chevrolet Aveo. The reasons are fairly standard. First, before starting work, you should immediately understand the essence of the operation of the heating system of any car. Then it will be clear why the stove does not work in the Chevrolet Aveo. The heating system on modern cars is connected to the cooling system. Antifreeze enters the radiator heater, which is blown by a fan. Heated air is directed to the salon.

Main reasons

So, the Chevrolet Aveo stove doesn't work for us. The reasons may be the following:

- thermostat malfunction;

- breakdowns associated with the heater radiator;

- improper 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 sequence of actions is the same.

Differences appear only in the location of components and assemblies to be checked.

Preparation for work

All work troubleshootingstoves should be carried out only under the condition that the engine and its accessories associated with the cooling system are in good condition. To do this, check the level of antifreeze in the expansion tank. It should not be below the minimum, the engine itself should be easy to start and warm up to operating temperature. Often on the last paragraph there are difficulties.

Thermostat faults

This device regulates the thermal mode of the engine and allows it to keep its temperature in a narrow range. The stove, like the engine, also works efficiently only with a hot engine.

Therefore, if the motor does not warm up, the stoveblowing cold air. Diagnosed thermostat is quite simple. 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 top warms up immediately, then the thermostat is jammed in the open position. In this case, the motor will never warm up to operating temperature, as the antifreeze immediately goes to the radiator, cooling there. Accordingly, the heat exchanger of the heater will also not become hot. If the hoses remain cold after warming up, this is bad. Antifreeze in the radiator does not fall, and the engine will overheat. In both cases, the thermostat needs to be replaced.

Air traffic jams

Often when operating the cooling system due to itsleakage enters the air, which has the worst thermal conductivity. Then the stove does not work in the Chevrolet Aveo, or it starts working 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 airlock is quite easy to remove. Enough to drive the front wheels to any elevation and unscrew the cap of the expansion tank.

After that, start the heated engine and rhythmicallysqueeze and unclamp the pipes leading to the tank. Antifreeze will gurgle, and the excess air - out. From time to time it is necessary to pour 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) pressure. Often its replacement can eliminate several faults at once.

Problems with the radiator stove

Often the reason why the stove does not work"Chevrolet Aveo", becomes clogged heater heat exchanger. It is clogged with dirt, deposits from the engine block, rust, and does not warm as it should. Cleaning here is almost useless. Since for this you need to remove the radiator, it will be more reasonable to replace it.

Faulty fan motor

Another common reason whyin the "Chevrolet Aveo" stove does not work, are purely electrical faults. Initially, cold air is blown by the fan to the radiator of the stove, which then goes to the salon.

A special flap directs this air throughradiator either bypassing it. Consequently, in the event of a malfunction of these nodes, the air will not blow at all or is sent equally cold at any positions of the flap. In the first case, the fan motor does not work. In the second - defective cable damper. When a motor breaks down, the search for a problem should be started with a fuse responsible for this circuit. If it is not pierced, then the wiring is faulty, or the electric motor itself, which is to be replaced or preventive cleaning. To remove it, it is necessary to dismantle the glove box. The motor is located at the bottom of the heater body and keeps on the latches. To repair the valve actuator will need to remove the bottom of the console.

Malfunctions of the resistance unit

The electric motor of the fan works with several speeds of rotation.

For this is a separate block of resistances,retarding rotation When it fails, the motor will work at individual speeds or only at maximum speed, directly, without resistance. In this case, the most reasonable is to replace the resistance unit. As a result, warm air is blowing out of the dampers again.

Control unit malfunction

The control unit may also crash orincorrectly regulate the temperature in the cabin. Its malfunction is one of the reasons why the stove does not work (Chevrolet Aveo is not an exception). Defective knobs on the panel may also act incorrectly. The control unit itself is rarely repairable and should be replaced. Another reason for the malfunction of the stove is the failure of the air temperature sensor in the cabin or its closure. In this case, the stove will always “fry” to full or blow cold air. After all, the feedback occurs through this sensor.

Conclusion

So finding out the reasons why notthe Chevrolet Aveo stove doesn’t work so hard. Knowing the structure and operation of the system, as well as representing the sequence of actions, you can confidently deal with this fault yourself.
