RE: Heated seats and auto windows
My window seals also freeze and do funny stuff in the deep freezes we've been getting in Chicago this winter.
It seems to be the stripping at the bottom of the window, where water naturally collects under a bit of sunlight, freeze overnight, don't let the window do it's "auto-crack" thing, then you go to close it, and it won't fit under the stripping at the top.
If you just let the car warm up first, the interior heat generates enough warmth to thaw the window seals, then open and close again. It's a PITA, but kind of a necessary evil to having doors without the edge all the way around the glass, but still tight enough to not whistle when they get old.
