Failed relay. Pull the proper relay and replace. I had this occur once and had the dealer do it under warranty.

Move the clutch and see if you can see where the play is. Also look at where the shaft comes out of the water pump. There is a weep hole at the bottom that when the water pump is on the way out it tends to leak a little out of. This means the shaft seal is starting to leak mostly caused by a bearing going out causing partials to rip the seal up. If you don't see any real play in the shaft then just replace the clutch. Now understand that metal does flex a little but excessive is what we're looking for.

i looked and there is no leaking. it looks like the play is at the fan clutch. there isn't a lot of play but there is some.( when i say play im talking about when i move it towards the front of the truck and back to the firewall).. i have had many cars and have done a lot of my own work. but after reading/hearing all of the horror stories about durangos. im a little worried.lol

If you have a failing fan clutch, this would explain why your electric fan never turns off. Your E-fan is now working full time to try to keep your durango from overheating. Address the fan clutch issue first. One way to know if the relay failed or stuck in "ON" mode, start the durango when it is cold. If the E-Fan comes on right away, then address the relay issue. If not, then the E-fan should be okay.

The horror stories about the Durango?????????

Just like any car of truck out there "if you take care of it they will take care of you". Just replace the fan clutch and do your regular maintenance.

I think it is on the wires. Just check the connections on your Electric Cooling Fan so that you can determine the real problem. Or you can ask for the assistance of a local mechanic to help you out.

So how did it go, j00?

The Jeeps have a same type of problem with the fans, ck the fuses in the PDC. What happens only on the 4.7L motors starts to blow a fuse the engine will not crank and the fan stays on. ck your fuses and then ck the relays like indydurango had said.
