The radiator fan was running when I went to start my Jeep. I discovered the fuse was blown and removed it. I need to go get a new fuse but am afraid driving it without the radiator fan working will cause damage. Yes, I am a woman......
As long as the store isn't 20 miles of stop and go traffic. You should be fine to drive if you keep a decent speed that will allow air flow. Yes, I am a man......

My daughters jeep had the same problem. We fixed by finding the wires that run beside the manifold down under the car. The conduit that have the wires in it was worn away because of resting up against the manifold, causing the wires to short the system out. Once I replaced the conduit and taped the wires it has not shorted out again. By the way, the Jeep dealer couldn't find the problem.

Check the wiring from the relay to the fan motor, and check the wiring from the fuse block. Basically check all wires that supply power to the fan motor, use a volt meter. Fan Relay (behind headlight, under battery) on the 2001 GC 4.0L are a piece of ****, I change mine almost yearly. The problem is their location, a high heat area prone to the elements. I understand that 2002 and newer, the location was changed and the problem solved. Relay might close the circuit when cold or at reasonable temps, but might open a circuit when it heats up, causing the problem.
we have a 2003 and it did the very same thing . Its called cooling fan relay it costs about 60.00 and is located behind the headlight assembly . not very hard to fix if you know anything about cars .
SOURCE: where is the radiator fan relay switch on a 2002
check under hood in fuse relay box. Map should be underside of cover.

There's a thermostatic switch that kicks the fan on and off. It is apparently shorted, causing the fan to run continuously. Check with your local auto parts store -- you be able to replace the switch without having to replace the entire fan assembly. In the meantime, pulling the fuse is a lot better than disconnecting the battery. You won't lose computer memory, clock, stereo memory, etc.
