Moin together, is probably a well-known problem with 9000s, and now it seems to have caught me as well: The windows fogged quite violently from the inside in the morning. Sweetly it doesn’t smell, the floor mats are not wet either. I still notice that it doesn’t get really warm in the car. What can that be, heat exchanger? This funny air valve motor? The AAC is refilled every 1-2 years, don’t think the ices? Car is a 97er CSE with climate automatic.. Thanks & Greeting 9000CSE
