I just replaced the module myself on my 2004 because the wipers/washer went crazy, it is a pain in the butt getting the cowl off and you have to buy the whole assembly to get the module, it is all fixed and cost $271.00 and an hour of my time which I didn't charge myself for, this site and HUMTECH are the greatest , I have fixed several things on this truck myself that I would have never tried without this site. Next project is to find that annoying rattle in the dash!
