So I just bought this car for my son. It has sun roof. Rained the night I had bought it from dealer in morning found water front driver side. Tested sunroof drains makes it to both front wheel wells. Crawled under dash saw stains above sunroof drain grommets by at least 6 inches, up in this white Tanish caulking and has water drops on it. I'm not a mechanic could this be leaking from driver side door mounts or hood mounts?
