the usually whisper quiet operation of my wipers has turned into a loud mess. I had to replace the windshield on my '08 (damn big rigs on the highway!), and of course the weather was really nice, so I never had to check out how the wipers were operating... but I think the wiper mechanism was somehow moved. the passenger side blade now rests about half an inch or so on the plastic trim piece! I checked out my wife's car (same prius, but different color) and the passenger blade comes to a lovely quiet stop about an inch or so above the plastic piece... is there a relatively easy way to readjust the position of the wipers/mechanism? the constant banging scratched the heck out of the plastic, and messed up the rubber of the blade so it streaks when in use. thanks in advance for your help!
