Where is the cooling fan relay located and how do I change it. My fan quit running and I know the fuse is good. I had this problem 3 years ago and the relay was replace then at the dealer. I would like to do it myself but cannot find it. Any help would be appreciated.

The fan relay in the 2001 cherokee is in the relay box which is located in the engine compartment on the pass side of the motor in a long black plastic box. On mine it is right next to my coolant overflow bottle. The relays for many parts are located there and the relays are labeled on the top of the box which comes off the bottom part. Many of the relays are interchangeable so you can remove the fan relay and try another 5 prong relay to see if that is your problem.

Where is Fan Relay located? Do we replace Fan Assembly to correct idle overheating?

I have a 2003 Jeep Grand Cherokee with a 4.0 straight 6 cyl engine. It has 17,000 miles on it and has been running fine. I took it to the car wash today it has been 28 degrees here in NJ. After I returned home I noticed the electric radiator fan was still running even after I shut the enging off. I went outside a while after and it was still running. I took the care around the block to see if it was just a fluke thing but the fan stayed running after I shut the engine off and did not stop. As not to run my battery down, I open the fuse and relay distribution box in the engine compartment and removed the square green 40 amp fuse or relay that stopped the fan. I put the fuse back in and the fan came back on. I will leave it out until tomorrow morning when I leave for work. I have a 35 minute ride to work and I will see what the fan is doing when I get there and shut the engine off. It was fine until I got the car washed today at our local car wash. Have you run across this before?
Thanks,
Harry

Hey Harry,
Sure have! There is a solid state relay behind the right headlight assembly, ( a real @#%@% to change too!) There is an issue with these failing either not allowing the fan to work or turning the fan on continuously. Let us know!

Hi Chris, Thank you for the information, I purchased the fan relay today. You said the right side head light, did you mean facing the hood or inside the car. Is it passanger side head light? I see my relay came with screws and rivets depending on when my Jeep was made. My Jeep was made Oct.2002.
Let me know
Thanks,
Harry

My radiator fan won't stop running when I turn the ignition off, killing the battery. Is this a belt issue? I removed the battery cables, can I drive it to a shop or will it overheat? 95 Cherokee.

SISSY LIZ,

Forget the shop. At least for now

Hook your battery back up and take that "Puppy" to Advance Auto or Autozone. Or another popular auto store.

Sound like a relay is stuck or burned

Merry Christmas!
