I have a 2001 durango 4.7 and the electric fan on my radiator does not kick in when I turn on my ac. I have cold air when I am driving, but when it's idling the ac gets warm. I checked the fuses. They seem to be ok.

Any help would be appreciated. Thank you....

 

did you swap the relays around to make sure thats not your problem

 

yup, try swapping the relay with a known good one (horn relay maybe) if that does not do it unplug the fan and see if you have 12v going to the harness with the A/C on, if you do then the fan itself is bad

 

We swapped engine relay with a/c relay and started the truck. Relay is good. I will check the fan tomorrow. Thank you again.
