Yesterday, for the first time, I heard a sound coming from the front passenger side of the compass. It sounded like it was near the dash/windshield. It is very loud and almost sounds like the windshield is trying to crack apart. Sort of sounds like rocks hitting the windshield maybe. Kind of hard to explain but it is very loud. It seems to happen whenever the body flexes and/or goes over a bump. Has anyone else experienced this noise? It came out of nowhere. It's not TOO cold here - highs in the 20s F during the day - so I don't know if it's temperature sensitive or not. It wouldn't bother me if it weren't so damn loud. The first time I heard it I was waiting to see a crack form in the windshield. Any ideas of what it might be?
