I have an 02 silvy and my father-in-law has an 06, both ext. cab and we both have problems with alot of wind noise coming through the back side windows. My question is if anyone else has this problem and if there is anyway to make them seal up better so no noise can be heard?

 

I believe some guys moved the mounts slightly so the windows would shut tighter. There are a lot of threads about it if you search.

 

You can buy longer arms so it pulls the window in tighter.

Still had too much wind noise for me. Siliconed mine shut

 

I think I remember GM having a different latch that closes the window tighter. I've never had any wind noise from my '01.

 

There is a seller on ebay that makes longer arms, but the air noise never goes away 100% unless you glue the window shut. How many people actually use that window anyways?

 

My 4 year !!! He's gotta open them all the time.

Are you guys sure its not the door weather stripping? I really dont have wind noise from the rear window, but i do get some occasionally from around the door i believe, was going to try some new weather stripping since mine is almost 12 years old.
