You have to stick a ratchet (1/2" socket) up through the door hinge cover opening it is up there about 10" use extentions so your socket handle is in the door opening so you can turn it. If you can hit it with some penetrating lube from the top I would advise it. If it is stuck it will twist the end of the venti-pane channel they usually don't break they just twist the channel. Look at the one that came out the weld nut on the bottom is what you are breaking the bolt out of, it is not uncommon to find them in the bottom of the door having fallen out over the years, was the first one missing?
