This broke over the weekend. It will allow the window to open, but will not close the window. The entire case pulled out, and is broken where the handle pushes in. Thank you so much.

Thanks for posting. When the 'worm gear' the handle connects to pops out like that, it's a sign the entire window operator needs to be replaced. I can't really make out your operator in these photos, but I suspect it is either the 39-031 or 39-155, depending on the length of the link arms. Compare with the diagrams below to see what matches best. For a new cover and handle see the 39-107 and 39-114L.
