Diagnosing the Cooling Fan
If your car is overheating, the cooling fan might be the culprit. Start by checking the fuse box. Look for a blown fuse related to the cooling fan and replace it if necessary.

A malfunctioning fan relay or a faulty temperature sensor can also prevent the fan from engaging when it should.
