  1. hi I have 07 jk & water leaks at a-pillar l&r side every time it rains. I took it to jeep dealer they water tested could not find leak.but when it rains it leaks they had my jeep for two days. I do not like going in to dealership

  2. I also have an 07 jk and have leaks. I pulled up on header seal where it contacts windshield frame and sealed it with black RTV silicone. This helped with dash leak,but still had passenger side door leak. Had to fix it with foam tape. It took some trial and error to get foam in the right area above the door,but I think I’ve got the leaks stopped. I bought my jk used and 3yr warranty is out. I have had leaks and death wobble . I had to fix both problems myself,but I wouldn’t have been able without jk forum.
