What Causes a Car Fan Not to Spin?

[EllianaLee]

Car fan not spinning reasons are as follows: 1. Water temperature not reaching the required level: Most car radiator fans nowadays operate with electronic temperature control, so the fan usually only starts spinning normally when the car's internal water temperature reaches the required level. If the temperature is too low, the radiator fan will not spin. Therefore, if the car radiator fan is not spinning, the first thing to check is whether the water temperature has reached the required level. 2. Relay malfunction: If the water temperature is appropriate but the car radiator fan still does not work, the issue might be with the fan's relay. A faulty relay can prevent the car's radiator fan from operating. 3. Thermostat switch problem: If there are no issues with the above two aspects, then the thermostat switch should be inspected. Sometimes faults can occur here, which can also affect the operation of the car radiator fan, so it's important to check this as well.
