I may have missed it, but I did not see posted the year of car you have with the Window Regulator issues. I know the Pontiac grand Am in some years has the scissors type non cable system " piece of crap " in my thoughts. Put your window down about half way and then try and pull up on it with a little effort, see if the window comes up or if it seems fixed. Let me know what you find out and I am sure I can help you out.
