What vintage is your GM? I assume it's a manual hand crank set up. I would make sure the track on the bottom of the glass that the rollers ride on are cleaned of old grease and relubed with the proper lubricant. Usually a white lithium based grease. Same goes for all the pivot points of the crank assembly. If the problem only occurred after the new glass was installed, I'd say the vertical felt strips that guide the glass needs to be adjusted. Usually you access these adjustment points by removing the inner door panels.
