It started yesterday. I shut of the truck and the electric cooling fan is still running. I finally got it to stop by cycling the ignition switch many times. It started immediately after clipping the TMR wire, but continues to happen even if I reconnect it. Any ideas?

I think the fan works off of coolant temp, so if it wouldent turn off even if the vehicle is shut off untill the temp is down.......

The stock e-fan runs off the A/C and the engine temp, but only when the ignition is on. When the truck's off, the fan shuts off.

Well, I found the problem. I have a burnt fan relay. I also blew the fan fuse just now. Parts places don't seem to have them, so I have to go to the dealer tomorrow for a relay.

If the relay was going bad and sometimes shorting out, that would explain the odd fan activity.

Is that correct that the e-fan will kick on to keep coolant temps down? Why would they bother with a clutch fan at all? Why are people installing thermo fan switches when removing the clutch fan? I am curious, because I am getting ready to install a switch for the fan myself.

On my 2000 the e fan when crazy on the morning i went to trade it in for my R/T. I had to drive up from va to n.j. and about half way i stopped to get some lunch and well the e fan wouldnt shut off. It was december and pretty darn cold out so engine temp wasnt the problem. I couldnt figure it out so i just told the guys at the dealership that its supposed to do that cause the engine is warm from the drive. :biggthump

I am still looking to find out if the e-fan tuely does kick on by high coolant temps, so maybe I don't have to install this switch I bought...

It kicks on at 210 and shuts off at 195.

Thank you. I found similar info in the manual as well, but it didn't mention temps.

had the exact same problem with our '01 Durango. I took the relay apart and could see the contacts welded together.
