I have an 87 GMC Wrangler, and my wipers are screwed. They are no longer
intermitent. When I put it to the lowest settings, it's just on a constant
slow speed. And when I shut it off, the wipers won't park. I have to twist
and hold the end of the switch until the wipers are near park position. This
sucks. Someone told me it's a ground problem. But I have no idea what to
test. Does anyone have any ideas. They would be greatly appreciated.
