Press down on the arm to free the bushing from the track, and then push out the window until the bushing clears the track.

The new crank cost us $150 with tax. Be sure to estimate costs before you begin.

Can you tell me how to fix if the guide on the top and bottom of the windows have come out of the track that is mounted to the sill? There doesn't appear to be damage to either. The riveted link keeps you from realigning the pieces, so I am tempted to unscrew the metal reinforcement from the sill, but am concerned that the riveted link will still keep you from getting them realigned. Please advise. Thanks.
