Great website. Thanks so much to whoever documented their work.
My 03 WJ just overheated as well, upon troubleshooting, I found that the fan was not turning on at all. I assumed the fan went bad and bought a replacement ($150). Hooked it up before installing it and still wouldnt work. Seeing as how I checked the fuses and relayes in the box next to the battery, I started searching for the relay under the headlight. Short of removing the bumper I couldn't find it. I will now cut a hole and swap it for a new one. Anybody know how much one will cost. Thanks.
