Fuses are good Replaced coolant temp sensor Fan runs with direct power jumped to it But radiator fan won't run on it's own and it overheats Sidom Veteran / Moderator Oct 4, 2009, 11:39 AM Post #2 of 3 (3503 views) Re: Radiator Fan not running and overheating Sign In If you've test fuse #10 and it's good, you will need to test the relay. This is a common problem on these. As long as you have power, ground, good wire going to the motor and a signal from the PCM, then the relay is bad. If you have a scanner with bi-direction controls you can just try to turn it on with that if not then you will have to go old school & run it to test for the signal. It's a pulse width modulated relay so it will look like a module. It's located behind the right bumper fascia below the right headlight (thank you Chrylser ) profleet Novice Oct 4, 2009, 6:09 PM Post #3 of 3 (3498 views) Re: Radiator Fan not running and overheating Sign In Yep an absolute blast to change, most common problem associated with this concern. I found a way to cheat these but it was last summer and I can't remember how I did it. I know it would require a good set of hand tools to complete this repair.
