Passat B6 windows fog up after rain/snowfal

[georgiangelov]

Hi all, my 2006 Passat B6 is getting on my nerve. After a rain/snowfal, when the sun sets, i get condensation on my windshield (and some on the back window). I have a sunroof - the drains are cleaned and water is running down freely. My floor carpets are bone dry, im not losing coolant, the AC drain is clean, the cowels under the wipers are cleaned from debris. From where is this fking water coming in ???

Stop exhaling. The moisture in the cabin is likely from your breath. The dew point of the cabin air goes up until it's higher than the glass temperature. The cold glass causes the moisture to condense on the surface.
Two remedies: Warmer glass and/or lower dew point.

Check to be sure that you aren't operating with the air flow on 'recirculate'.
I leave at last one window open about 5 mm to allow for some exhange of the moister interior air for somewhat dryer outside air. I also use a scarf or face mask to avoid projecting my exhalation directly to the windshield. I run the cabin air direction with some at the windshield to aid in further deflecting my breath away before it reaches the glass.

it happens when it has been raining and after sunset, without me being present in the car
