Question about 2001 Jeep Grand Cherokee

1 Answer

Fan still doesn't work.

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.

My 2000 Jeep Grand Cherokee overheats in idle and when the A/C is being used, have replaced thermostat, relay switch, radiator and water pump what could be the problem.


Sounds like your radiator fan is not working.
Have your replaced the fan or fan motor?
Fan motor will cost $100 /diy
Also, check for recall on this fan and motor through Jeep

2001 Jeep Grand Cherokee Laredo radiator fan doesn't turn on.


Check power to the relay. it can close, but if there is no power to it, it can't send anything to the fan.
signal goes from sensor, to the computer, to the relay. when it closes it transfers power from the hot side to the fan.

This means your thermostat is bad. Needs to be replaced. Also do coolant flush.

Fan won't come on


RADIATOR FAN WORKS OFF OF THE COOLANT SENSOR NOT THE IAT SENSOR. CHECK YOUR RELAYS AND ALSO SEE IF IT COMES ON WITH THE A/C AS THIS OVERIDES THE COOLANT SENSOR FOR THE FAN. MOST LIKELY CAUSE WOULD BE A FAN RELAY

01 grand cherokee fan relay/oil pressure


I don't know if this will help anyone, but i had a issue with my jeep running hot and check engine light coming on as well. After alot of trips to different shops - the last one found that there were two senors in the engine for the fan that need to be changed. Everyone would aways fine the one up top but not the second one. After that, have not had any other problems like it since.
