rolling up the passenger window yesterday and got a "pop". Then the window crank did not raise the window. Have pulled the panel and loosened the winder mechanism. It is connected to the system that holds the window. I can see a curved, toothed gear which I assume is the lifting mechanism. Thinking that the crank mechanism has come adrift of this geared lifter. Does anyone have pics of the situation? It appears as though everything in the door is riveted together. How is the system removed or replaced? Any pics would be greatly appreciated.

Thank you
