The water temperature has come up, and the warm wind blows the cool wind.

In the cold winter, many drivers will choose to turn on the seat heating and warm air as soon as they get into the car. But many car buyers show that their car's warm air is not very hot, so what is the problem that causes the warm air to be not warm? Don't worry, let's talk to you about the primary reason why the car is not warm enough.

The car heater is not very hot. Why?

There are many reasons why the car heater is not very hot. The most common are the following categories:

1, after the refrigerator is running, the engine temperature is low, and it is not easy to heat up when the warm air is turned on, which should be normal and can be handled after the automobile engine is warmed up;

2. Check whether there is enough automobile antifreeze. If it is not enough, the radiator will not be enough. Of course not. When this happens, people can only solve the problem by adding automobile antifreeze.

3. The water temperature sensor is turned on too early, which leads to that the frozen liquid is always in the large circulation system, and the temperature of the frozen liquid is always maintained at a low level;

4. There is air resistance in the refrigeration system of automobile engine, which leads to the poor circulation system of the refrigeration system and the common problems of high temperature and cold and warm air.

The temperature rises, and the warm wind blows the cold wind.

We need to check whether the car has a cooling button. Generally speaking, the automobile's refrigeration button will be instructed by the "A/C" button. When the refrigeration button is pressed, the compressor will be turned on, and then cold and warm air will be blown together, which will lead to the decrease of the warm air temperature. If the problem still occurs after shutdown, you need to check the temperature sensor of the water storage tank. If the sensor fails and the cooling fan is always on, the warm air will get cold.

What is the abnormal noise when the vehicle is cold and warm?

The squeak of warm air is probably due to the insufficient lubrication of the rotor, which damages the gap between the motor stators and leads to the gap. When the fan is on, the speed ratio is very high, and of course there will be a clicking sound. In this case, only the damaged rolling bearing in the blower can be removed and replaced. If the fan is seriously damaged, it is recommended to remove and replace it at the same time. Vehicle blowers rarely have problems in daily application, and it is generally impossible to have any problems in inspection during maintenance.
