High Pitched Whine (Not Rear End)

Glue it back down and no more noise... was one of the hardest things to diagnose, b/c on a lift it would never happen (no airflow over the car) and it was intermittent on the street. Once the air lifted the plastic it would make the noise, but when coming back to a stop the plastic would fall back down on the windshield and you'd never know it!!!

Man, how'd you figure this one out and how long did it take? Open sunroof give you the clue?

That makes 2 for 2. I had my rear carrier bearing along with the entire driveshaft replaced 3 years ago under warranty which gave a squealing metal to metal noise that took the dealer 3 trips to figure out. I also had the upper weatherstipping come partially undone this past summer on my windshield and experienced that squealing noise as well until I glued it back with some silicone adhesive. It was very audible with the sunroof open when doing 60+ mph. Easy DIY fix.
