MY 2000 JEEP CHEROKEE IS OVERHEATING. I HAVE CHANGED THE THERMOSTAT AND WATER PUMP. I HAVE AN ELECTRIC FAN. I DO NOT HAVE A FAN ON THE ENGINE. I HAVE CHECKED FUSES AND THEY ARE OK. DOES ANYONE HAVE ANY IDEA. AS LONG AS YOU ARE DRIVING THE ENGINE STAYS COOL BUT WHEN YOU HAVE TO STOP A LOT IT WILL BEGIN TO OVERHEAT. HELP

I can find a diagram of the switch for you. But as with the ac compressor, I would sugest having someone look at it as it will be hard for the average joe to fix. The switch could be causing it.

Have you checked the refrigerant charge? You do this with a set of gauges or with a single gauge that your local WalMart or autoparts store should carry. It is check on the LOW PRESSURE ONLY side of the system. That is on the passenger side near the drier (large cylinder close to the firewall). If a system is low on refrigerant, it will cause the compressor to cycle on and off. There is also a switch in the same area, on top of the drier or close to it that senses the amount of refrigerant in the system (pressure switch I think) that could be bad. I would at least purchase a gauge and check to see what it shows is in the system.

Are you saying that an electric fan was installed in place of the belt driven fan?
