    Is it on defrost? My gf leaves her Jeep on defrost year round and the sound of that fan drives me crazy as soon as you start the vehicle.

    It's going to be one of your fan relays or the temp switch in the rad.

    The warning says the fan CAN run without engine on , not SHOULD run. There i sstill something that makes it run all the time, which is not normal at all.
