One of mine quit working so I took it apart and found that the plastic piece inside that controlled the movement had broken. I did find some places that claimed they could fix air wipers online, but decided to try epoxy to repair it. It works, but have decided that I'll replace the air motors with electric ones down the road. I prefer having the wiper controls on the turn signal switch with intermittent and washer control like all my cars.
