What Causes the Corolla Fan Not to Spin?

[VanFernando]

Corolla fan not spinning reasons and solutions are as follows: 1. The coolant temperature has not reached the required level. Most car radiator fans operate with electronic temperature control. The fan will only start spinning normally when the engine coolant reaches the specified temperature. If the temperature is too low, the radiator fan cannot rotate. Solution: Check if the coolant temperature meets requirements. If the temperature consistently fails to rise, inspect the engine. 2. Relay malfunction. If the coolant temperature is appropriate but the car radiator fan still doesn't operate, the issue may lie with the fan relay. A faulty relay will prevent the radiator fan from working. Solution: Replace the damaged relay. 3. Thermostat switch failure. A malfunctioning thermostat switch can also affect the operation of the car radiator fan. Solution: Replace the faulty thermostat switch.
