With the arrival of cold winter days comes frozen windows. I had to work at mine for a few minutes before getting the door open. And I was thinking, since the Vent button on the phone app drops the window about 2 inches, maybe that'd free frozen windows more easily then the normal window drop from opening the door. Tried it on my car tonight, which had frozen windows after a car wash, and 3 of the 4 cracked loose fairly easily. The right rear door took some pounding. We need a way to stop windows from freezing. Wax the bottom of the glass maybe?
