Good day.
I bought a used Audi A4 2.0T Quattro a few days ago.
I like the car.

I have noticed that when I lower the driver side window for a few minutes and then raise it, there is condensed water vapor (like steam on a bathroom mirror after shower)
I has happened on passenger side also but not today, when I checked.
THis is NOT supposed to happen.

I did a quick search for this problem on youtube and have not found it.

Have any of you experienced this problem?

The window up/down was working intermittantly 2 days ago, but today it is ok. I wonder if the moisture is causing this issue.

Thanks for feedback
