I rarely have anyone in the rear seats of my car, so I've only just discovered this.
There appears to be a lot of moisture on the windows on the rear doors of my 2007 A3 Sportback once they've been lowered and raised (Picture 1). All that water smearing is on the inside, but only when the window has been lowered and raised.
I first noticed it when I saw this from the outside:
The drain holes are free from debris at the base of the doors (it's on both rear doors) so I'm at a loss.
Has anyone seen this before?
