If the cylinder works but nothing happens to move the window then I would wonder if the cylinder has become disconnected from the regulator. The cylinder fits into two rounded notches on parts of the scissors action regulator. Each end is held by a spring steel clip. The clips are double sided and slide over the flat portion of the regulator where the notches are positioned. Tension of the clips hold the ball like ends of the cylinder in the notch in the flat metal. Clip opening is shaped sort of like an hourglass so the ball ends can move in the notches. it is possible a clip broke and has allowed either end of the cylinder to fall out of the regulator.

Here are a couple of photos showing the notch and ends of cylinder. I don't have a clip to show what it looks like but it is about an inch wide and maybe slightly longer. It slides over the flat portions of the regulator and grasps the rounded ends of the cylinder.
