I am not sure what is causing this, but whenever I roll my windows up from full down, there is a wet streak starting from the front of both windows, ending about a third of the way back, on the inside. The wet soon becomes dry, leaving nasty streaks. I think it is from spraying the windshield wiper fluid, while driving, with the windows down. Does anybody else have this problem. Any help would be appreciated. Thanks.

 

I have this also, I think its water from rain, washes, or other sources that get down just under the weather stripping on the door, so when you roll down the window. As it glides across the weather strips, it picks up this stray moiusture.

 

There are numerous threads on this. Seems that MINI gets a little carried away with the grease. Mine was really bad when I got it, but over the year it has gotten better.

 

Is there any way to fix it, or just deal with constant cleaning of the windows?
