I've seem to have this problem for a while now, although it got worse after my windshield got replaced, I guess the guy messed with them or whatnot...When they should park they don't fully go down to park position, the passenger side moreso than the driver, and when at full extension during a wipe, the drivers side actually goes too far and off the windshield a bit. Is there some way to adjust these to be correct?

That'* a good question and a PITA problem from the sound of it. I don't know for sure, but it would seem to me that maybe the windshield guy removed them completely from the wiper motor drive shaft and then did not replace them correctly.

Since I've not had mine off, I would have to take a good look to see how those are mounted before I could make any good suggestions. However, it would seem to me that there is some sort of method to keep those in alignment. Likely either a splined mounting shaft or something similar.

Anyone out there know?

all you have to do is pull them off the Shaft and turn a bit and then put back on.
its a spined shaft and you can put the arm on at many diffrent positions.

There is a small tab on the top side of them (aka window).

Lift the wiper arm and hold gently to release pressure at the base. Using something that won't marr the paint of the wiper arm..gently move the tab outward from the arm. (it'* hinged on one end.)

Using both your hands lift up on the base of the wiper noting the positioning. Reposition and push the tab back in to lock it on.

Fixed it tonight...thanks guys!!!!
