2017.5 Platinum here. Water flows freely down the sunroof drains. Can't figure out why there's still water on the driver's side. Car has been sitting in the driveway for a week. Pulled the A pillar and there was a bit of moisture inside on the plastic. Hose connection at the sunroof was completely dry. Poured water down it and it poured right out of the firewall. No leaks that I could find. Pulled back the carpet and backing on the floor and it's wet. It's wet behind the big foam thing behind the carpet. Can't get to the firewall connection for the hose so I'm not sure how to rule that out. Anyone ever have this problem when the lines are clear? It shouldn't be the AC as it's been sitting. The sunroof hasn't been opened in over a year. The car only has 36k miles on it. Driving me crazy...
