So I hadn't adjusted the mirrors from the inside switch for maybe a year. I hadn't had occasion to use the rear wiper for six or seven months. Now they don't work. Fuses are okay. No burn smell either. Before I take a hammer to them to try to get their attention and unfreeze, I thought I'd ask the forum for any suggestions. What do you think?
(Main components run beautifully on my 185,000 mi year 2000 Cherokee Sport. But airco unit failed late summer, and I put in a bypass for $90. Will do a correct fix someday. New tires are Cooper ATV 235 75.)
