How does one adjust the park position of the wiper? Is it really just undo the nut, reset to desired position, and you're (more or less) done?
Went through an automatic car wash and at the other end the wiper had moved from its park position on the passenger (right) side to straight up the middle. Hmmm. Turned on the wiper and after a couple of swipes it settled down happily in full coverage. But now they're parking on the driver (left) side.
