I had a BMW 3-series coupe and that's what I did. The window would freeze and not seal properly every winter. The wind noise was terrible. But it would work fine again when the weather warmed up.bigbengt67 said:I'd warm up the car before opening the door, if you don't have remote start try crawling in from the trunk. People with BMW 3 series coupes have the same problem and thats what they do.
