The fan right behind the radiator is not turning off once the vehicle is off. Is there some type of relay that allows the fan to turn off/on? Anyone have/had this problem. I searched the forums but everyone has problems with it not turning on, mines its not turning off. Thanks.
most common cause of this is a failure in the fan assemby itself. The fan has a small final stage unit built in to it which is what fails and causes it to stay on.
