So my wife was sitting in the back with our 1 month old and she noticed her seat belt was damp. It was damp on the section that can't be seen. I'm thinking it's either my gamiviti rack leaking. The middle mount is literally right above the seat belt, but I'm unsure if it can drop onto it. (hard to believe because I went extremely overboard with the silicone). OR I'm thinking it's the pop out window seal. I have noticed some water lines on the inside of the glass sometimes after the do it yourself car wash. Anyone else have this issue? Are those seals hard to replace?
