I noticed when driving with just the drivers window down you get a bad wind buffeting inside the cabin-Our 08 Civic does the same thing-Any body else experience this?I have to crack a back window just to equalize the noise this causes.Any imput thanks

 

get those window visors from honda? they can let you crack your windows down a little big without getting that buffetting sound

 

I have the same issue with ours. Drop the rear windows just a tad and not only does the buffeting stop but the interior cabin noise drops significantly and the entire car cools off quickly.

This happens on a lot of cars and opening another window usually solves the problem, it has to do with the pressure when only one window is open. The window visors will also help cut down on some noise if you drive with the windows down a lot.
