What are the reasons for the car's air conditioning fan not spinning?

[MacBrianna]

Car air conditioning fan not spinning reasons are as follows: 1. Poor contact of the air conditioning switch: If the air conditioning switch has poor contact, it cannot control the normal startup of the car air conditioning, leading to the fan not spinning due to the failure of connection. In this case, the air conditioning control switch needs to be replaced, and attention should be paid to whether the connecting wires of the switch have short circuits. 2. Damage to the fan motor coil: If the fan motor coil is damaged, the fan cannot receive power normally, resulting in it not spinning. In this situation, the fan motor coil should be inspected and repaired, and if necessary, it can be directly replaced. 3. Fan bearing detachment: When the fan bearing is detached, turning on the air conditioning causes only the bearing to spin idly without the fan rotating properly. In this case, the fan bearing needs to be reinstalled and secured.
