Will order a new one and replace it, I just don’t get how the fan can run with truck turned right off....

A lot of parts on the X5 have power supplied all the time and they're operated by a pwm module that pulls to ground. When something goes haywire and that's switch doesn't open and stays closed whatever it's operates will stay on
