I began hearing a noticeable wind noise on my 13 GS several months ago. It sounds as if the window is cracked open at any speed above 30mph. After sitting on the passenger seat (it sounds like it is coming from he passenger door) and being driven around, I replaced the sunroof gasket and then every front passenger door gasket, including the glass channel, in turn. No change. The noise is incredibly annoying. Anyone else have this issue? Thanks!

 

Fold your outside mirrors in while driving and see if the noise goes away. My 18 does this occasionally in cooler weather and stops when folding mirrors in. It doesn't happen often and I just live with it.

 

No joy. There is no difference with the mirror folded. I can't imagine why the temperature would matter anyway. In any case, I have never heard this noise since I bought the car new in 2013. Thanks for the suggestion.
