Why is the car fan not spinning?

The reasons why the car fan does not rotate are: 1. The air-conditioning filter element is clogged: the warm air is not too hot. First check the air-conditioning filter element to see if it is dirty or blocked. Dirty air-conditioning filter element can indeed affect the coldness and heat of the warm air. If the air conditioning filter is dirty, the air blown out will be very small and you may not notice it. 2. Lack of refrigerant: Lack of antifreeze will also affect the warm air. Because the warm air uses the heat of the antifreeze, the hot antifreeze enters the warm air water tank, heats the warm air water tank, and then blows out through the warm air water tank as hot air. If there is not enough antifreeze to rush into the small heater water tank, the amount will be reduced and it will not be fully filled, so it will not be so hot, so the air blown out will not be so hot. 3. The heater water tank is clogged: The heater water tank is blocked and the antifreeze cannot enter the heater water tank or only very little antifreeze enters. Therefore, the heater water tank will not allow hot air to blow out after passing through it. It must not be hot. If the heater water tank is blocked, it is better to repair it. Trouble requires removing the entire dashboard to see it.
