You have two fans, one to cool the radiator, and one to heat the cabin.

..

check fuses and coolant temp sensor
the coolant temperature sensor unit ( that is SENSOR not gauge sender unit) sends a report to the ecm to turn on the radiator fan when the temp is reached
If the fan is not coming on then the circuit is broken--sensor, wires ,fuses relay, fan-ecm
all have to be checked out

No rad fine check the fan is working ,either the fan motor ?? connection to the fan motor ?? fuse ?? relay?? or temperature sensor?? any one of these will cause the fault

1 - Upper seal board
2 - Radiator reservoir hose

4 - Fan motor connector
5 - Cooling fan assembly
6 - Condenser fan assembly
7 - Oil cooler hose
8 - Radiator hose
9 - Radiator bracket

on the cylinder is a sensor for the fan relay when sensor shows trhe temperature is high it will operate the relay for the fan so either the sensor is faulty or the relay ,Also check for a live feed to the relay incase a fuse is blown or a dirty connection with the fuse holder

Not good.

First, it would be nice to know WHICH fan you are talking about. The engine cooling fan? The heater-A/C blower fan?

Second, this might be the time to educate you about fuses. Fuses do not cause electrical failures, Electrical failures cause blown fuses.

With that being said, it is highly unlikely that if you find the fuse you are looking for, that it will solve your problem.

The diagram you requested appears below:

The diagram is usually under the hood on the radiator support or underside of hood. If not autozone will give you free diagram.

Hi there,

I hope below steps can help..

1. Disconnect the ground cable from the battery terminal. 2. Disconnect the fan motor connector. 3. Loosen the radiator drain plug to drain the coolant. 4. Disconnect the upper and lower hoses and overflow tube after marking the radiator hose and the hose clamp the ease reassembly.

Cover or plug the hose and inlets of the radiator so that dust and other foreign material etc. can not enter after the hose is disconnected from theradiator. 5. For vehicles with automatic transaxles, disconnect the oil cooler hoses from the automatic transaxle. 6. Remove the air conditioner condenser fixing bolts and radiator bracket fixing nuts. 7. Remove the radiator and the fan motor. 8. Remove the radiator fan motor and condenser fan motor from the radiator. Regards, Jeep Brainy
