Question about Jeep Grand Cherokee
The electric fans never kick in on my wifes 2006 Grand Cherokee. 3-7L. If the thermostat is no good, will that cause the fans not to work? I checked all the fuses. They are good.

CHECK THE FUSE BOX ON THE DRIVER SIDE UNDER THE HOOD. CAN BE EITHER YOUR COOLANT TEMPERATURE SENSOR NOT WORKING TO LET THE FANS KNOW TO TURN ON OR YOUR THERMOSTAT IS STUCK CLOSE OR THE FUSE FOR THE FAN MAY NEED TO BE REPLACED.

The fans are turned on by the PCM, if the PCM is not telling the fans to turn on, they won't even if everything tests fine.

Remove right front headlight cut out the plastic right below where the headlight rest on. Just a 4"x4" square and take out the plastic there you will see the relay,2 screws and remove the relay. Patch the hole with duct tape and put the headlight back, no need to remove the grill or bumper.
