The Stovebolt Site Forums The Shop Area The Electrical Bay Grouding for Wiper Switch?? (1958-59)

I thought I had an issue with my switch. When I first tried to use it with a new motor
the switch needed some deoxit spray and it worked. But felt a little strange in the off /low /high.
Not a well defined transition. So when I tried this year, the wiper does not work.
I figured the switch finally went and needed a new one. I found one NOS ,installed it. Wiper still does not
work. I`ve traced everything and I think I have a ground issue. My question is,
Does the switch have to be grounded to the back of the dash? There may be rust there. I feel the motor is
properly grounded. I just put a new one in. It worked fine till it sat for a few months.
