Just went through a problem with my wipers on my 88 Wrangler, they quit working totally. The module on mine is to the left of the steering column, if you trace the wiring harnass out of the bottom of the steering column they plug into a 2x4 module and then continue up to the main harnass. I lucked out in that mine ended up being caused by a mouse nest I found above the steering column. Mouse piss must be corosive! Cleaned it up and now even my washer works. My jeep sat in a horse barn for 4 years before I bought it, still smells like hay when it gets wet. Gordie
