A couple of times recently when I have come out to the Mini (R56) first thing in the morning (when it has been a couple of degrees below freezing) and tried to get in I have found that the drivers window seems to be frozen closed. After a couple of goes the window finally drops enough so I can get the door open. If I then try to get the window to go down further, with the door open, It still sticks but after a couple of more goes it starts to work normaly. Has anyone else had this happen as the Mini dealer says there is nothing they can do and that it is a common problem. It does not seen right to me and sounds as though the mechanism is freezing up inside the door.

 

Wurth Rubber Seal treatment seems to work well for me.

 

I had something like this happen just other day. The culprit was some moisture on the front corner of the window that froze to the rubber. I just let the car warm up for a while and it was fine. But I intend to grab some of that rubber seal stuff at some point.

 

I've found that just smearing a thick layer of Vaseline over the outside of the side windows keeps them from sticking...
