My 2006 Suburban has a terrible air leak noise when cruising down the highway, and I can't, nor can the dealer identify where it's coming from. They replaced some trimming, but they have not removed or reset the windshield. I'm guessing the seal is screwed up somewhere. I even used duct tape around the entire windshield (except the bottom cause you can't) to help seal it and figure it out but it still is loud. Is this just an issue I'm gonna have to except, or is there something wrong. You can hear the wind noise over the radio.

This noise is way to loud to be normal. If it's normal then I'm selling this thing.
