I have a 72 and one of the rear windows is off its track. How do you access it? I took off the little plastic vent thing in the door jamb but can't reach it from there. Do I have to pull off the interior panel? If so how does it come off?
Thanks

Yes, you have to pull panel off. You need a tool to get window crank off, and another to pop panel off. Available at most auto paint supply stores.

They sell the crank tool at Auto Zone, Advance etc (look in the "Help" rack), and I believe they have the panel popper too. Great and cheap tools, they will save you a lot of aggravation. Adjusting the window can be tricky if you don't do it in the right order, it can be like two steps forward and one step back. The Fisher body manual shows how to do it the easy way.
