Well, I laughed when I read that the problem would fix itself but, for half a day, it did... my passenger window worked like a charm. But now its back to being broken again and, much to my stupidity, I see that I didn't quite close it all the way when it did work: I heard the wind coming through the tiny gap this afternoon.
Hopefully it will work again soon!
