We had our first snow event this weekend. My son called to say that something broke in the mechanical drive mechanism for the windshield wiper when his wiper stalled on a frozen section. He hears the drive clanking, but the wipers don't move. It's a 99 Contour. The repair CD is no help. Has anyone else had this problem? What breaks? What's to fix? My problem is that the car isn't where I am.Thanks again.
