It would appear that the relay is located on the cross rail that runs across the front of the vehicle (in front of the radiator). I found out that it is riveted in place by a single rivet, so in order to replace mine, I will have to remove the rivet and use a self-tapping screw to secure a new one.
The fan relay is located in the fuse panel located under the hood beside the battery. It will be marked under the lid. Make sure you check the maxi fuse for the fan also.

Yes your fan relay has failed . Pull you right front headlight assem out . Look threw the holes in the plastic that the light assem set in, it is underneath the plastic screwed to the body. You can pull the grill assem off to get to it or you can cut a 2 by 2 inch hole where the channel is in the plastic where the headlight goes. Citting a hole there wont cause any problems. If you cut a hole , cut it at about the center of the channel at the half way point from the front to the back. This is a solid state relay so it looks different then your typical relay.

The relay is located down at the left lower corner of the radiator support. Little flat box, like a box of matches. common to be bad.

The Radiator Cooling Fan Relay Switch for a 2003 Jeep Cherokee is located behind the bumper on the passenger side underneath the headlight.
There are two ways of accessing it:
1. Remove the bumper.
2. Remove the pasenger side headlight assembly and cut a hole in the plastic underneatch click on the link below for more info.
The relay seems to be a common replacement item for this vehicle. One cause of the failure is that the relay overheats, per a note inserted in the replacement part packaging.
The cutout method is used by dealers. In one vehicle, the relay failed again after 40,000 miles or so. While replacing the relay it was noted that it was secured by one screw and it was not tight. This did not provide thermal contact with the chassis which helps cool the relay. The cause of the second failure was likely due to improper installation. Trying to work through a cutout would seem to make it difficult to get both screw isntalled securely. Furthermore, the new parts today use steel pop rivets for installation to help guarantee it will maintain proper thermal contact with the chassis. The pop rivets cannot be isntalled without removing the bumper.
It is not difficult to remove the bumper and grill to get to the relay. It sounds like a big deal but you are talking a half dozen screws and less than a dozen plastic rivets. The act of cutting a hole and working in cramped quarters has to be more difficult and it does not provide as quality a job.
Hope help with this (remember rated this post).
