Anyone have experience with a damp seat belt on the Gen4? After each heavy rain, the driver's side seatbelt is cold and damp when I pull it out. (The passenger one is dry.) I first noticed it after the interior windows started fogging from the back toward the front when the outside temperatures went cool in the fall. I already checked and or fixed the usual culprits to water/humidity in the passenger compartment, including: replaced the cowl and seal that was leaking and soaking the cabin air filter; checked and cleaned the front door bottom drains; checked under all front and rear floor mats; and checked the trunk for leaks.
