Replace the fan relay switch. The dealer will charge you 400 to pull the bumper off, or you can buy the part for 45 and cut the hole in the plastic near the passenger headlight assembly and replace it yourself. There are instructions for this procedure on the web somewhere. I have had this problem more than once with my 02 GC V6.

The fan relay is under the pass headlight I removed the headlight and cut a hole in the plastic to get to it. its in the middle cut about a 4 or 5 " sq the relay is right there. no need to take the front of car off. when done i just glued the plastic back and done.

Depending on where you live your local parts store usually will help you with their computer,they have pictures where the part should be,and will gladly show them to you.Dont count the dealer out,if you ask nicely most of the parts departments will help you.

you electric fan probably isnt working with vehicle warmed up lift hood and watch temperature gauge when it starts to over heat check to see that fan is working if not it could be the fan relay or fan itself if the fan does turn on its most likley the thermostat

1999 jeep grand Cherokee Laredo a/c electric fan not turning on.I've already replaced the relay, it worked for a very short time then it won't work again, water thermostat also has been change, no help.


There is a resistor mounted by the fan, this could have burned out. Look on passenger side right by fan motor should be 2 screews that have 5-6 wires pluged into it had to replace mine once fan only on high worth looking in too. Also, check if the blower motor Resistor Harness was faulty.

Good luck.

To check it run wires from the positive and negative battey posts directly to the fan motor connector. If it doesn’t run the fan motor is defective.

the only problem that vehicle has is with cooling fans is relay/module or electrical harness to module that burns up located behind and under right front headlamp assy must remove headlamp to access relay/module that is what powers up fan motor module assy.
