Up this morning and the temp was about -4 degrees ish, door of the outdoor stored g29 was slightly frosty on opening. When I tried to close the door it would not shut as the window was frozen in the fully up position and would not drop slightly to fit into the door seal. It took half an hour with heating on full blast on the door to get it to move at all and another couple of hours before the window would perform as it should. I thought I had burst the window mechanism and didn’t want to smash the window. Any one had this and suggested solutions. Cheers
