Could have done with this earlier in the week! Windows were frozen and wouldn't go back up but would go down. Did try putting the drivers side down all the way, didn't go up but closing the drivers door helped and was fine after that. Got some gtechniq g1 on my windscreen and that wasn't frozen except where it was dirty (where the wipers don't touch), so I now have some g5 on my side / rear window so heres hoping that helps stop those freezing
