Our wiper motor failed two weeks after we bought the coach, and would quit right in the middle of a rain storm. We nursed the issue by using the intermittent position and following the directions on smartwheel manual by pushing the button once, and then counting by seconds how long we could wait before needing to clear the windshield, and then pushing the button again. It defaults to a 30 second interval I think, the second push shortens that cycle. But when the snow in WY was going sideways, and it finally just quit. We got to a place, it cooled down and we were able to go on our way, changing out the motor fixed the problem and it works perfectly now. It's much quieter now as well. You can find out who to order the new motor from in the ACA Tech section of the site.
