The electric cooling fan on my 1999 Jeep Grand Cherokee will not turn off, even with the keys out of the ignition. I have turned off the AC (per the amber inside switch) and even turned off the fan with no success. The only thing I can do to save my battery is to disconnect it. HELP!

My 99 jeep cheokee limited has a similar issue but the fan will not turn on. if i go over a bump or turn hard the fan will kick on but other then that it stays off. I also put my hand in front of the vents and the faster i go the more air will blow out. it is very cold so i believe it is A/C. I think it might be a bad fan switch on the control panel of the dash? Anyone else hear or see this issue and know how to resolve it.

I found me having this problem you never said where it was located.

I think this year, the fan relay may be located behind of the front bumped on the frame of vehicle

2003 GC: My fan does not switch on. I checked the fan and it works when directly connected to the battery, so it has to be related to something else. Does anyone know what the relay looks like to try switching. I switched the two bigger square ones, but it did not fix the problem. Any other ideas?? Thanks!

ok guys, here is what I found, I have a 2001 JGC, that the fan realy went out on, the fan worked fine when attached directly to the battery, I got the relay, which by the way is a dealer only item. It is located behind the facia, under the battery, on the passenger side fenderwell. You have to remove the headlight, and front facia, although there is a chance that you can remove the passenger headling, and cut a hole in to reach the relay, two simple bolts hold it in.
