Q: Cooling fan

asked by on

Replaced cooling fan relay. Cooling fan still comes on after the car is off. Happens at least once a month. It's will drain my battery when it comes on with the car off.

My car has 54000 miles.
My car has an automatic transmission.

Hi there. It is common for the raditator fan to keep running for about a minute or less after the engine is shut off; especially if the engine temperature is extremely hight. Typically when the fan keeps running after the vehicle is turned off, it’s caused by a relay that is bypassing the ignition relay input. It might be best for you to have a professional mobile mechanic complete an electrical problems inspection to help you pinpoint the source of this problem
