Thanks to all who have responded to my post. I have hot wired the fan to the battery and it does not come on. So I will be taking it in to my mechanic tomorrow to diagnose my problem. Thanks again.

i had the same problem, its the engine control computer. The ground feed to the fan control module is lost from the ecm when the a/c system is run for the about 30 minutes.
$1000 plus diagnostic $180

1993 Jeep cherokee overheating. Changed water pump, and fan clutch, did pressure check on ststem, put on a new head gasket. Still overheated, took out the thermostat, put it back together without one, changed the antifreeze solution to the water wetter and water. Still overheats. Will run at about 230 at 45 MPH, but turn on the air or go faster, temp climbs. Electric fan is running. HELP!!!!!!

I have 1995 Jeep Cherokee, 4.0 L. I drove about 2 miles, the temperature gauge was going to red section. I must stopped to drive the jeep. I changed the thermostat, but the overheat problem still was not solved.
Please give me an advice.

I also have a 1993 cherokee with a heating problem I have replaced the engine, water pump, theromstat, viscous fan, radiator and all of the hoses I also replaced the fan temp switch located in the theromostat housing and the sender for the gauge it is running around 210 all the time I installed a 160 deg. thermostat no change I blew out the raditator and flushed the cooling system I thought it might have an air lock so I pulled an 8lb vacum on it for about 5 minutes with no change any ideas

I finally solved mine by replacing the radiator. I found a guy with a laser thermometer who checked the radiator temperature, almost 50 degrees difference from the top and the bottom. Since the radiator was about 130 bucks at advance auto, he suggested that I just put in a new one rather than sending it to a shop to get it cleaned out. That did the trick, stays below 200 now, even with the air running.

I also neglected to add that I cleaned my A/C condenser. Upon close nspection, the fins were not bent, but the spaces between them were partially filled with sand particles and paint that had peeled from the condenser over time, not letting good air flow through to the radiator.
