Question about 2002 Jeep Grand Cherokee
I replaced the fan relay and the engine light stayed on and the fan still dosent work
If engine light stay ON, I suggest scanned the PCM to know ecaxtly what fault code is stored there, this code number could be related with fan malfunction.
If you dont have a OBD scanner reader, just turn the key at ON (dont start engine) three times, On-Off-On-Off-On and read odometer as Pxxxx codes, note this and come back again with this information.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Under the hood in a black box on the drivers side or passingers side look for alot of wires going in it.
The part Chrysler supplied came with an incorrect diagram and instructions. The note said the "LEFT" headlight and the diagram illustrated this along with a note to remove the air snorkel. Your answer was the correct direction. It is the left headlight as you FACE the car. The headlight was removed by taking out the 10mm stem nut and gently using a pry bar, outside edge first, then inside edge. Trying to remove the headlight rapidly will result in a broken plastic tab that will need to be epoxied.I used my 2" hole saw to create an access by cutting through the headlamp plastic cavity behind the headlight, a strong light will reflect onto the relay and you can see the bracket part below and between the battery and front frame toward the front of the car. With the headlight assembly out, I prised the white ball socket fittings and oiled them for ease of refit. The piece of the cavity was saved because it is critical to keep water out of the relay area. There is a small red tab on the connector of the relay that needs to be pressed and the red tab moved to the side. Then insert a screwdriver into the bottom of the connector to release the black plastic tab that locks the connectors together. Hold the new relay in your hand. Push the red tab back across the connector body and push the two halves together, they will now lock It is critical that a good flat install be performed or the part will fail and you're out $75 and the time to redo it all over again. Use the new screws in the part bag, the old ones will not tighten enough for a good grounding of the part. I used metal duct tape to tape the plastic piece back into the hole and then sealed it with two more pieces. Pressing the headlight assembly back works best if you start from the outer edge and then press the bottom edge in.
Also, I suggest review the Service Manual for WJ Grand Cherokee.
