Sounds like your cooling fan relay is bad the jeep grand cherokees are known for this, first thing i would do is unplug the radiator cooling fan and run 2 jumper wires direct from the battery to the fan connector if the fan kicks on your fan motor is good and the relay is bad, if the fan doesnt kick on replace the fan motor with a new unit, the cooling fan relay on your particular model jeep is located under the passenger headlight and requires you remove the front bumper to replace it, however some people cut a small hole under the headlight to access the relay the faster way but if your not to keen on cutting holes in your car remove the bumper and replace the relay if the fan checks out and you wont be overheating anymore...
When the rad fan runs and the ignition is off, the only problem that is common on the chrysler system would be the rad fan relay. The relay contacts are welded together inside it and replacement is the only fix. It is located on the left fender beside the battery. There is a slight chance that your wiring to the relay may be faulty causing a short to ground that may allow your relay to remain energized, but that would be a rare instance. Good luck
dont think so,seem to remember a reostat somewhere at the bottom of the rad right hand side ,check for earth problems as well ,sorry if vague but i seem to be forgetting things as i get old .
If there is not power at the cooling fan motor, then a likely cause is the cooling fan transistor (Relay) which is located bhind the front bumper underneathe the right headlight. The bumper must be removed to reach it, but many people cut a hole below the removed headlight to gain access.
check if the cooling fan cuts in if so see if the radiator is hot? If the rad is not hot probably needs a thermostat if it is hot could be water pump or head gasket
I would check the radiator fan in the car for looseness. If the fan wobbles or moves , Then change out the radiator fan. The radiator fan and motor come as one piece. There is a fan relay also should be replaced.
When turning the key only half way to make the dash fan work, indicates that the dash fan is okay.
The dash fan may make a whining or high pitch noise when engage. Then I would change it out because an internal bearing to the fan is going out.
Check the temp sender and wiring? Checked pin #16 on the black computer harness plug for temp sender signal? checked power and ground at the relay?
