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.
