I'm thinking either your motor is defective or something isn't set up properly. Maybe the wiper arm length or position is off, or the 90° sweep is too much.

Mine work great and if anything they park too low if the windshield isn't wet enough. They physically can't go up onto the roof when they're off, the park mechanism doesn't allow the shaft to move.
