What is the reason why the cooling fan in the car radiator does not work?

2022-11-25 15:16

When we use the car, we find that the car cooling fan suddenly stops working. What caused it?


1. Air conditioning filter element is blocked. The function of the air conditioning filter element is to prevent dust from entering the vehicle. After a long time of use, the air conditioning filter element will have dirt, odor, or even blockage.

2. Fan relay fault. If the water temperature meets the requirements, but the cooling fan still does not rotate, the relay of the cooling fan may be faulty. Generally, the relay is damaged due to poor line contact.

3. The temperature control switch is faulty. Today, most of the cooling fans used in cars use electronic temperature control to work. The cooling fan will not work properly until the water temperature reaches the desired temperature. The cooling fan can work normally only when the water temperature reaches certain requirements.


The above points may be the reason why the car fan does not work. If you need more information, you can click our homepage for more information. If you need to buy auto radiator or condenser and other accessories, you can also contact us, and we will provide you with better prices!
