Window Tip-In Adjustment
I found the instructions below on the web about how to adjust the side window tip in for a C5 coupe. I don't remember the source, but I just wanted to augment this procedure with photos.
I was getting wind noise on my driver's side window at speeds above 70 mph, and not the passenger side. I was going to adjust the blow-out clip towards the rear of the car one position, like I had also heard about. But upon closer inspection, I noticed with the door closed and the window fully up I could see the top edge of the window (the edge has a cloudy, or a rough finish). Which means it wasn't fully seated into the top portion of the weather stripping.
So this is why I chose to do a window tip in adjustment vs moving and/or adjusting the blow-out clip. My brother was also getting wind noise above 70mph. But his window was seated ok in its weather stripping. So on his we moved the blow-out clip.
