I have a 2007 1500 Silverado Crew Cab, new body style with the sunroof. Live in FL and with all the rain we've been having, sunroof is leaking through the control console on the roof, and the trim at the top of the seatbelt mounts. The dealer has already tried to fix once. Bringing it in again for a 2nd time this week. They replaced the gasket and drain tubing last time...What else can they do? Didn't spend $40K on a truck in Florida to have it leak when it rains!!! Anyone have any fixes, ideas or similar problems?
