Hi, if you have replaced the sensor which turns the fan on and off and you have also replaced the relay then the only thing left that could be faulty is the fan motor itself. double check you have wired it up correctly and also double check the coolant is getting hot at the top and bottom of rad just to rule out thermostat or water pump being at fault then really all you have left that could be causing the problem is the fan motor itself.

one thing you can do to test the fan is to short the two wires together and see if the fan runs the wires that come from the fan to the sensor if you can get some wire to short between the two wires as well as having it still connected this should then get the fan working if it dont work then the fan needs replacing

Thermo fans running on after engine is cool


Faulty switch, relay or wiring on earlier models. Later models probably have the cooling fans operated via relay(s) by the engine management system.

I suggest you check on a wiring diagram how yours are operated if checking the relays, switches or sensors don't bear fruit.

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...

I have a 99 Jeep Grand Cherokee, that is running hot, cooling fan is not working has a ground doesn't have power. If I jump it out the fan works. What controls the power?


I have the same problem with my 99. I am going to try to jump it to test if it's the fan itself that's dead, which I doubt it is. If it works when I try to hard wire it then it's either the fan fuse, the fan relay or the temperature sensor that is bad. I am thinking I have a bad temp sensor which is what tells the fan to kick on when the coolant is warming up. If my fan works when hard wired then I am going to jump it off one of the fuses that is only on when the vehicle is running. I don't think it will hurt anything to always have the fan running while the car is running.

Cooling fan not kicking on causing the jeep to over heat. Replaced the termstat and temp sensor, on a 00 jeep grand cherokee.


Check the fan operation by disconnecting the fan wiring. Using the battery use a set of jumper wires to see if the fan runs directly off the battery.

2001 Jeep Grand cherokee cooling fan runs on


Likely your fan relay internal contacts have burned closed. Relay should be either in the power distribution center or in front of the battery.
