    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.

    One thing missing from that list: Sunroof drains - if you have one ;)

    I highly suspect sunroof drains as well if you have a sunroof. I found the best way to clean them was to shove a straw down them and blow.

    You should see 4 little holes in the opening in the rooftop, one in each corner.

    You have no moisture anywhere else? Under the seat? Along the interior floor between door and seat? I agree with sunroof. The only other thing in that specific location and height is the door.

    Two ways to clean the roof drains that have worked for me:

    First and easiest is to blow compressed air through the drain line. If/when you can see water draining under the front wheel, it worked.

    If that doesn't, get some thick line-trimmer cord and snake it down until it comes out of the drain line.

    Good catch, all. I forgot to mention the sunroof drains, which I checked in late end of 2018 and didn't find any clogs. I'll check again at the first opportunity.

    I would use liquid, air, and something very flexible to fish through there. Lastly there could possibly be a leak in the sunroof seal itself.

    What you might really need is a torrential man made downpour while you sit inside it.

    I'm inclined to suspect the sunroof seal, given the cowl seal to the windshield was intact but still leaked so much it flooded the cabin air filter routinely. The top front of the car catches the sun year-round, so it would make sense the seals lose their flexibility. Challenge to the man-made downpour is that we can't see inside the sunroof edges or down the B pillar area.

    Well I would readdress the drains and do the downpour as that is easy and cheap. Downpour test and go from there. Process of elimination.
