Just trying to recall when I did mine. The window I think is under tension from the spring to stay closed. When it goes down past a certain point the spring tension seems to relax and let it stay down. However going up should take less effort than going down. I would check the coiled spring again to make certain it is up against the peg in the regulator. A long shot maybe and it has been a while since I did mine. It was a 53.
