I started my car this morning and all of a sudden the wipers came on and would not shut off even when the switch was in the off position. Then randomly when I got on the interstate, they quit and went in the park position. Then I drove the car to lunch and it was acting up again. Just as I was parking they quit wiping and went in the park position again. At work now so haven't looked at it again yet. Anyone heard of this and knows the cause? I'm thinking bad wiper switch...
