My 2007 Jeep Liberty that I never had problems with is pissing me off. The rear wiper goes crazy whenever it wants to. It works the right way when I control it myself, but will also go crazyby itself, even when the car is no turned on. I had the multifunction switch replaced, which was melted and they said that should have fixed it. It was good for about a week now is doing it again... I wonder if anyone else has had this problem?????
