wipers don't return all the way to the rest position
I just bought an '02 Park Avenue Ultra. The windshield wipers don't go all the way to the rest position. They seem to work ok, they just don't go all the way back down to the guide stops.
I removed the cap on the driver side wiper arm and removed the nut thinking that the arm would be mounted on a toothed nut or something to allow positioning of the arm, but the arm didn't seem to want to lift up and I didn't want to break anything so I left it as it was and reinstalled the nut and the cap.
