Yeah, that is the fan"s PWM module (control) your looking at. My dealership had replaced it due to a recall or TSB before I purchased my Xfire. When they reconnected the fan to it they plugged it in reverse polarity. Boy did it make a lot of noise when it turned on

Anyway, it sounds as if that is what's gone bad since you are getting voltage to it. If it was a recall, your dealership (or any Chrysler dealership) should replace it for you.

Hope this helps.
