When I run the AC which is often this time of the year in Oklahoma, and shut her down, the electric radiator fan continues to run without shutting off. I can understand maybe a 15 - 20 minute run after engine shut down but even after 30 - 35 minutes it still continues to run. I thought maybe the relay was dirty/stuck and cleaned it but that wasn't the cause. It will stop when I pull the relay and reinsert it. I understand there's a fan sensor. I assume that could be the culprit. Does anyone know where it is on the 4.0 litre or any other suggestions? thankyou.....Pete
