Window winder

I am replacing the passenger side winder mechanism, but have ground to a halt....everything is unbolted but the cable runs behind something at the top of the door and I can't seem to get it out.....I have unscrewed ascrew but I can't shift what I assume is the window runner....how does it move?

Thanks in advance!

Unfortunately, need to remove the quarterlight window.

 

thanks all I will try again!
