When that plastic cracks like that, it means you need to replace the whole operator. These are built into the operator itself, so it's all technically one part. We can help, but I'll need you to remove the operator from the window in its entirety so that I can see the whole thing. I unfortunately can't make it out from this photo since it only shows the base. |

I don't know what your operator is, so I can't really say. However the video below may be of some help. I can't know if yours works the same way, but I suppose it's a place to start. |
