I had the same problem last summer. I had to pull the door panel and discovered the window had over ran its stop and "over cam'd" itself by falling down to far. This due to that BIG mainspring coming undone. I managed to raise the window by hand then it took off. I ended up limiting the travel
by fabricating a rubber block and placing it in the bottom of the door frame for a quick fix.
Didn't feel like pulling the whole track assembly out to rewind the mainspring at the timer . Another project.
