What is the solution to the problem that the car fan is not hot?

1, the cooling system of automobile engine encounters air resistance, which leads to the failure of normal operation of all automobile refrigeration cycles, thus causing the problem that the warm air is not cold. If the inlet of the warm air small water tank is hot and the outlet is cold, the small water tank is blocked and must be removed and replaced.

2. The car water pump is damaged or lost, which leads to the decrease of water consumption flowing in the water tank, which in turn leads to the warm air not being hot, so a new water pump must be replaced.

3. It is also possible that the water temperature sensor has been turned on all the time or turned on too early, which leads to the repeated early work of the cooling system. Moreover, the temperature outside the car is low, and the external cold air quickly cools the antifreeze of the car, resulting in insufficient temperature rise of the water tank and insufficient warm air heating. The water temperature sensor must be adjusted or overhauled.

4. The reason for the appearance of warm air running components may be that the filter element is blocked, so that the exhaust air volume blown into the car by the fan is insufficient or the distribution of cold and hot air is unscientific. At the same time, it is also necessary to check whether the speed ratio of each gear of the fan can reach enough, and check whether the control flap hook of cold and warm air falls off and should be repaired immediately.
