It is an automatic fan which is operated by a sensor and works according to the engine heat (it can start off even when the car is not running). It will stop by itself in a few minutes.

OR there's a short circuit somewhere.

Saturn cuts off when trying to use the a/c


It could be more than one problem.
The cooling fan could be running because the temp sensor is sending the wrong signal to the computer.
The ac compressor or clutch could be bad causing a heavy load on the belt and the engine.
I would unplug the compressor clutch and see if the engine still bogs down with the ac engaged.

Electric fan wont kick in jeep over heats replaced thermostat and two sender units


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...
