Question about 2001 Jeep Grand Cherokee
Electric fan is not coming on at all, checked fuse and it was fine, disconnected fan and checked for power at fan, had no power, is there a relay? If so where can I find it? what controls the fan? Is there a temperature switch?
The electronic fan relay on this model fails very often, causing the problem you describe. I attached a picture of the location.

Had this happen on my Jeep. There is a Solid State relay located underneath the passenger front headlight. Most major auto parts stores carry the relay. Unfortunately, you either have to take the front bumper off and the passenger headlight off to get to it, or take your headlight out, and cut a hole through the metal under the light to get to the relay. I opted to just take the bumper off. Really simple fix, just a pain to have to take bumper off.

I change my rad fan relay once a yaer like clockwork. Four of them n the last three years. I removed the right headlamp assembly and using a 4 inch hole saw drilled carefully through the plastic underneath. You can change relay in about 5 minutes after that. Use a piece of rubber and a couple of rivets to cover the hole and re-install headlamp assy. Garage wants about 6 hours labour to change th relay.

I have the same problem with my jeep. Talked with a dealer and was told that it is because they don't get enough air to cool down. So I went to my local auto parts store and got all the colors of wire,somebutt connectors with heat shrink, wire ties and a piece of wire loom. I went down to the relay gave myself enough wire to work with, about 3 inches from the relay connector and cut each wire, remember that their is power in the wires so don't cut at one time, Add enough wire to mount the relay up on the fire wall so that it gets more air flow to cool off. Now use **** connectors with heat shrink to seal out the weather or you are asking for trouble down the road. Now put on the wire loom around the harness you just made and tie off harness in safe areas. This make it easier to change not time if you have to. Two years and going strong with this fix.

That flat spot, #2 screams to me for a heat sink.
keep it cool and it might last 20 years.

Hi guys. for all of you that are having problem with this fan sensor, that not only fails often but can put the vehicle in a severe overheated condition and cause you to spend lot of momey in an engine overhaul. This is what i have done and never ever have an overheated engine. I simply replaced the electric fan with a slip clutch fan. Easy to istall and good bye to this problem. Hope all you cherokee owners Happy motoring

Hi is it the 4.7 v8 if so u need to check your viscos fan hub to make sure its engaging with the motor off spin the fan there should be some resitance but if there is none and fan spins freely then u need to replace the fan hub.

suggest that you rent a pressure tester from auto zone or advance auto and preform a pressure test on your cooling system. follow the instructions on the test of pressure to your cooling system,also check for coolant leaks onto the ground from radiator area. may be bad water pump,broken hose,heater hose,upper radiator,lower radiator,or a bad radiator itself. a simple pressure tester will reveal the coolant leak. but make sure to follow the instructions with the pressure tester,as you can damage your coolant system otherwise. thank you for choosing fixya.com
