Yesterday my driver's window made a loud pop when it reached the up (closed) position. Today I pushed the button for the window to go down, and I think the window fell down instead of going slowly (I'm not sure because I was watching the passenger window).

Now the window won't go back up. When I press the button for it to go up, there is still a motor moving inside, but the window remains stationary.

I'm not sure what's wrong because I haven't removed the door panels yet. I was thinking a bad regulator or the window came off the track. Any ideas of what happened or what to look for when I remove the door panel?
