I think we can help, but we need a bit more information. Specifically, we need to see more of the operator. Your pictures only show the base and a portion of the arm. Can you show us a top-down view of the entire part? You don't need to remove it from the window, but we will need the window to be open so that we can clearly see the arm(s). Thanks!
