Norco crank

Home Owner from USA
This crank opens and closes my window fine until about the halfway mark, where it turns uselessly and doesn?t seem to get any traction. What part do I need to fix this?
Thanks,
Courtney

Sounds like the operator gears are stripped. Can you remove it from the window entirely and show us a photo of it by itself? I just need one clear photo that shows the whole mechanism. Thank you!
