There's a problem in the electric circuit working the windshield. You have to take it to a mechanic or an electrician who knows his way around cars.
Damnnnnnn that sucks
Maybe water got in?
If I turn my windshield wipers on to the intermittent speed they run fairly fast regardless of where I set the control. If I put them on high they will go even faster, but they can never turn off. You have to turn the car off to get them to stop. Also once you go to high, then wont slow back down to their intermittent speed. any ideas?
