pin pointing the noise on any car is half the battle....
I wanted to add that the dollar bill method is not infallible. I tried it and ALL doors at every point allows a dollar bill to be pulled out reasonably easy.
Trust me, I do NOT have an issue with wind noise everywhere!
I did have a buffeting effect on the driver's door from time to time.
Turned out that the window glass seal (hard rubber) had slipped down about an inch from the inside of the window frame at the top. This resulted in a misalignment to the weatherstripping on the upper door (body) frame.
From the outside of the car, you could actually see where the window frame seal had 'shrunk in and away'. It's very obvious with a white (or light colored) car. Probably not so much with a black car.
I used some weatherstrip adhesive and secured it with zip ties to allow it to dry in place for about an hour.
Now this seal remains in place and the buffeting noise is nearly eliminated.
Severe wind gusts can still create the noise, but I suspect that's unavoidable.
My 05 had it too. Right rear door, same symptoms. Dealer replaced quarter window and seal (under warranty!) and solved the issue. Look back through the forum; this has been a common issue for many and most have solved with the same repair.
had that noise car de compressed at highway speeds it took several trips to the dealer but they finnaly fixed it. they had to adjust the door so it would close tighter to make proper seal, i bet a good bodyshop would be better at fixing this than the dealer, if you use a delaership maybe try one with their own body shop
