Andersen 7191-33 operator

A home owner from Rochester Hills, MI says:
I'm looking for a part. The crank for the window stopped working. The only part I could find a number for was the outside casing, which said "Andersen 7191-33." However, it is the inside part (operator?) that may be a problem. I attached pictures to hopefully reveal what the problem might be and how I might fix it.
