Window won't stay up on retractable screen storm door.
(West Chazy, NY)
I have a Larson storm door with a fixed glass pane at the bottom and sliding glass pane at the top. There is a retractable screen attached to the top glass pane. My problem is, the top glass pane will no longer stay up only half way. The top window pane is either all the way open or all the way closed. I know this has something to do with the tension cords. As you can see them in the picture, they never used to do that. I know that they should be retracting when the screen is all the way closed. Does anyone know if this can be fixed. If so, could you point me in a direction?
