2001 Durango 4.7 electric fan

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?

Must be an Mopar a/c, guru on this site.

The elect fan on my wifes 01 4.7 durango hasnt worked in years with no over heating even with the a/c on. The only time it had overheated it needed a new water pump because the factory pump had a plastic impeller that cracked and wasnt circulating coolant. Or maybe you have a bad fan clutch?

Just replace the fan.. they go bad after a while ...Easy swap and rock auto sells oem replacements...my 04 Dak 3.7 fan was I think $78 and took 20 minuets to install..Had to change the fan motor on my 96 also ..EZ ...

On the 2003 4.7 there is also a relay to activate the fan. Both the fuse and the relay are in the under the hood fuse box. The cover has the placement positions of the fuse and relay. I replaced the relay at about 140K miles when I replaced the radiator. I believe the radiator failed when the truck overheated when the fan quit running.
