It takes about 5 minutes in case of rain until the windshield and all other windows are fogged. I have now checked everything. Water is not in the interior, the floor is dry for both the driver and the passenger side. Heat exchanger is also dense.

In case of rain it takes The only thing that immediately helps is the climate at 12 o’clock. After 20 seconds everything is free. Climate is out again, slices are closed again after a few minutes. What I notice, the air from the nozzles feels relatively damp. So I would suspect the evaporator. It was renewed a few years ago, so it shouldn’t have been spoiled. There are also procedures there. How can you check them? Where do they come out below?
