It could also be that the parking switch works fine and is parking right
where it is set to park. Don't know exactly how the late model cars are
adjusted but on the early ones you just loosen the top screws on the wiper
gear housing and rotate the raised portion of the cover until they park
where you want. It is recommended that you remove your arms and blades
prior to adjusting. This will keep you from trying to park them in the
hood.
