Question about 2001 Jeep Grand Cherokee
My 01 Jeep Grand Cherokee still overheats after replacing the fan, the relay, the sensor switch. Can the problem really be in the PCM? The fan does not work off the AC either and no power to the relay when ignition is on.
You may want to trace that relay power wire back. There may be a fuse under the dash that supplies power to it, and likely another in the distribution center. I'm fairly sure the pcm supplies the ground signal to the relay.
