On my '03, it's behind the right headlight.

You remove the headlight lens, then drill a 1" hole. The relay is behind that.

There should be pictures at www.wjjeeps.com.

Let me now if you need more info. Will be glad to help!

SOURCE: radiator fan not working replaced relay,temp

Check the wiring from the relay to the fan motor, and check the wiring from the fuse block. Basically check all wires that supply power to the fan motor, use a volt meter. Fan Relay (behind headlight, under battery) on the 2001 GC 4.0L are a piece of ****, I change mine almost yearly. The problem is their location, a high heat area prone to the elements. I understand that 2002 and newer, the location was changed and the problem solved. Relay might close the circuit when cold or at reasonable temps, but might open a circuit when it heats up, causing the problem.

You didn’t mention replacing the temperature sensor located on the block in the path of the ‘cooled’ coolant.
I can’t tell you any closer where to look for it since you didn’t specify which engine you have.
This device is a solid state item called a thermistor.
With the air temperature around 77 degrees F and a 'cold' engine, it should measure about 10,000 Ohms and hot, around 1,200 Ohms while disconnected from its mating connector.
With the ignition on, and the connector disconnected from the sensor, you should measure about 5 volts coming from the ECU.
If this has failed, the ECU is not getting the right info back from the sensor and doesn’t know if the fan is needed or not.

2004 jeep grand cherokee engine cooling fan runs slow


Could be either one, but usually its the fan motor.
You can run a wire direct from the battery to bypass the relay to see how fast the fan is able to run. The connector on the fan relay can become damaged too.

How do you remove the fan relay sensor on a 2004 Grand Cherokee


The fan relay sensor is behind the vacuum reservoir which is below the right (passenger) headlight and behind the bumper cover. Remove the headlight and remove the bumper cover. The fan relay sensor is fastened by two screws. You may need to drill a hole in the headlight 'saddle' to get to the screws.
