There have been a lot of postings in this forum about that same issue of pop and snapping. I have the same problem with mine. it only happens when it's very warm 80 to 85 degrees. I think it's the heating of the windshield pushing against the metal trim. It gets worse when you hit bumps. It tends to be inherent in these cars. I hate it also. If it cools off, see if it goes away. I hope this is what your referring to? I thought it was my blower fan for a long time, because I always had my air on in the heat.
