Hey guys looking for advice on how to fix an air leak i have on my 2010 sedan. I have traced it down to the rear passenger door and to the inside part of the small glass closest to the rear of the car. door seals all look good inside and out but when i have the wife in the back seat if she pushes on the trim inside of the quarter glass the noise gets better and worse. unsure if anyone has ran into this problem before and if so what did you do to correct it?

Thanks!

 

Never had the problem in the G, but in a BMW. I pulled the trim and put butyl putty (black stuff they seal glass windows with) in the place that was leaking air. Took a couple tries, was quite messy.
fwiw this was the non-moving quarter pane of glass in a 2003 5-series.

 

awesome. i might try that! its a tough spot to see unless your looking directly at it so some kind of sealant under the trim probly wouldn't hurt anything

Thanks for the help!
