I have not ever done a 59 but it should be similar to, if not like my 52 panel.
Pull the panel off.
To get the window out I think you have to take the vent assembly out. MINE had couple sheet metal scews and two small bolts holding it the vent assembly in. PLUS...on MINE there is a bolt in the very bottom of the vetical post...the one that the front of the window slides up and down it. You have to reach and take it loose. Once the screws, couple bolts right at the bottom of the vent assembly, the one on the bottom of the vertical post and the vent assembly should come out. You will have to sort of "half twist" it to come out but it is fairly easy.
The window then can be rasised up about one third and you can see the regulator arm that slides back in forth in the window sash. The sash is the piece that the window actually fits down into. When you turn the glass "up" the window should come out as the arm of the window regualator sldes out the end of the window sash.
Once the window glass is out you have about 3 or 7 screws that hold the regulator in. Take those out and the regulator should come out the inspection hole.
I would imagine you will also take the door control out to. Some screws hold it in and the latch. The latch is no big deal. Take the screws out of the door edge and the latch will come out with ease.
I just did mine and I like to clean up the regulator and sprayed them with hammered silver and they really look nice. Lube them some when you put them back in and they will work much better.
Hope this h helps.
OH...there is a nice TECH TIP in the tech articles about rebuilding the windvent which would get you to where you need to be. Itis well worth reading.
