Q: Cooling fan has low power and is not functioning.

asked by on

radiator cooling fan not working

My car has 140000 miles.
My car has an automatic transmission.

As you may know, the coolant fan is operated by a coolant fan relay that is triggered when the coolant temperature sensor reaches a specific level. When this relay is not working properly, the fans may work intermittently, all the time or not at all. This may also be caused by the coolant temperature sensor itself as well.

I would recommend having an expert mechanic, such as one from YourMechanic, come to your location to replace your coolant fan relay.
