Should there be a play in the window lift mechanism, seems like the small toothed weeel have a 60 degree play before the mechanism starts moving. Like the small wheel rotate a bit on its shaft before it starts to move the toohts on the lift mechanism.
The thin metal strip on the second picture, should it just lay in the frame and be bended in both ends to stay in place or should it work as a spring to keep some pressure on the window when it moves up and down?
