Hello all. I have a 56 3100. When I use the windshield wipers and then turn them off, they don’t. I thought there was an electrical switch in the dash and it was loose, allowing the switch rotate instead of switching to the off position. Needless to say, almost lost a finger. So now that I know it’s a mechanical switch, can anyone tell me how it works and ideas on how to fix the problem? How does the steel cable coming off the switch activate the wipers? Where does the electrical portion of the switch come in? Thanks. Thomas
