Help!!! My 2001 Durango is overheating. I have determined that the electric fan is not turning on. I can't find a fuse and my mechanic friend says the problem is even a 220 degrees the electric fan does not start. If I turn off the A/C and bring the motor up to 2800 RPM the engine cools doewn. What controls that fan? How can one test to find out if it is the fan or control device? Please help?? I need to find out !! Is there a Mopar A/C mechanic in the house?
