Hi guys, i have been having trouble with my wiper switch for my 69 Superior. It used to work when it wanted to. it also used to not turn off completely. When it turned off the wipers would keep going up and down about 3 or 4 inches and wouldnt stop. I took it apart and cleaned it. It worked flawlessly . I got my inspection sticker and the next day it quit completely. Any ideas on a rebuilding shop or leads on another switch?
