What do you do when your car fan stops working?
If the fan doesn’t come on, you need to look for a blown fuse or breaker. In older cars, you might have a fusible link – this is wire within an insulated block of rubber. Try to grab the end and stretch it. If the wire stretches, the wire link could be broken and you’ll need to replace it.

Unless there is an electrical issue, it may stay on all the time until it drains the battery. When the engine is running, the coolant circulates from the engine and flows to the radiator, where heat is dissipated.

If no voltage is recorded, you will have to replace the board or the relay. If there is a battery, check if it is working properly. This is another common reason behind faulty blower fans.
Why is the engine cooling fan not working?
The temperature sensor determines when the radiator fan comes on by reading the cooling system temperature. If the sensor isn’t working, your fan won’t come on because it won’t know that the temperature is hot enough to require activation, which can frequently lead to overheating.
