Hi. I have a video of this crank in action. It will open the window, but on reversing the direction of the crank, it just unscrews itself, and the window does not move. I can close the window by pushing from the outside while lightly turning the crank inside.

Hello! It looks like the worm gear stripped out. You'll definitely need a new operator.

I believe our best match will be the 39-015. I feel confident that this is what you want, but look it over and see what you think.
