I have a recent problem that I can't find where the issue is coming from. After a rain, when I pull out the seat belt, it is wet and has a mildew smell. Its not wet at the top, but most likely somehow gets wet behind the panel and gets into the retractor somehow. I don't see any leaks on the carpet or anywhere else. I don't see where it would be getting in from the door jam itself. It does have a sunroof if that matters, but I thought the sunroof drain goes out the passenger side. I also don't see any water or evidence in the roof liner. Anyone else experience this?
