I am pretty sure the manual states that the long wiper goes on the short arm and the short wiper goes on the long arm. The long arm goes on the passenger side and the short on the drivers. When I set them up that way I think to much of the drivers side wiper sticks up to far into the windshield with the wipers in the park position. Has anyone else seen this? If I lower it then I don't get a full sweep at the top of the windshield.
