Yesterday, I had my windshield replaced with no issue. However, now there is a rattling sound coming from the dash that goes from left to right when I make turns. It must have been something the technician dropped. Not sure what since there aren't any screws or whatnot that hold windshields in that I know of. I am guessing he dropped something in the vents where the defrost hits the windshield. How do I open that? Can I do that without serious disassembly?
