I have a 2000 Grand Cherokee 4.0 2wd. My electric fan went out. I have already replace the thermostat and fan relay myself. I hooked up two jumper wires from the battery to the fan conector and it doesn't kick on. I can't seem to get the fan assembly out, the manual that I have tells me to take it to a dealer but i would rather do it myself. Any help?

Make sure the radiator fan cycles when vehicle reaches about 220 degrees, if not replace the electric radiator fan and relay. The fan relay sits below the passenger headlamp. If that is working correctly you may have a cracked or warped cylinder head. Most shops can do a chemical test to the coolant system to check for combustion chamber gasses from cracked heads, the only drawback is that this test only tests for combustion gasses and doesnt usually show when the head has cracks between coolant passages

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...

If the fans don't come on to cool the radiator then maybe it's the thermal fan switch, which sends the turn on signal to the fan relay, that might be bad.

There is a resistor mounted by the fan, this could have burned out. Look on passenger side right by fan motor should be 2 screews that have 5-6 wires pluged into it had to replace mine once fan only on high worth looking in too. Also, check if the blower motor Resistor Harness was faulty.

Good luck.

Either your temperature sensor is unplugged or it has failed and is giving you that reading. (most likely cause...if not, start checking wiring from the sender and make sure any electric cooling fans are plugged in as well.

Your clutch plates are worn out & require to be replaced with a new one. The trany oil level should also replaced with fresh oil,.........................sodeep

i think it is your thermostat control switch, it is not giving the signal to turn your fan on when it is necessary

There is a cooling fan relay below the passenger headlight that is a common problem. Hard to get to.

When the engine is at operating temp check the electric cooling fan. If it is not moving then i would check the fan relay which is located under the right side headlamp. 9 times out of 10 this is the problem
