Driver's door power window

What have I done?, while trying to get the window to break free from our wonderful frozen Canadian winter something went clunk in the driver's door! I was cycling it up and down and something popped!, window still tugs in the upward direction when button is pulled upward, but will not go down!, I hear the motor working!, and it will go thru the auto cycle and stop, I hear something moving around inside the door when I close it, does anyone know what is going on? is there a cable or belt that has let go on the down side?, and ideas or what parts I may need for repair? any help is appreciated, thanks

The typical window failure involves the regulator. It has been associated with "stuck up" windows. I believe the parts to fix this run about $50 (dealer repair costs ~$300), but there's no guarantee that your problem is the regulator.

Tear the door apart and have a look.
