I may be jinxing myself, but I've found lowering all the windows (once a week or more often) minimizes the frequency of window regulator failure. I also get less wind buffeting if all the windows are open vs just the front two. 4 yrs 3 months since my only failure, which happened just after p/u in July,2005 (12/00 build date)
