I have a 2013 Town and Country that's been having a problem lately with overheating sometimes. The cooling fan is not coming on consistently. What I've done in a pinch is put a jumper on the low speed fan relay to force the fan on. I can drive it all day like that. Without the jumper I hear the fan come on some times. I think the high speed circuit is not working. Under automatic control (no jumper) often it's fine and doesn't overheat. I suspect that when the low speed is enough everything is fine. Then when the ECM calls for fan to run at high speed then it gets no fan and overheats.

I recently had to replace the ECM for other reasons. I had the exact same problem with the previous ECM so I am real sure it's not an ECM related issue. FYI I got the ECM from Flagship1 and I'm very please with the price and the unit.

I'm trying to find the fan high speed relay. I've seen two locations listed on the .net. One location is on the bumper, and the other is next to the radiator on the frame. My T&C has neither. I did find three relays, two right in front of the battery and one just under the battery.

Any help would be appreciated!
