This is a great guide - thanks very much!
A tip for anyone about to follow it, do close the door before you do the window reset at the end. The guide does say this but it's not clear that closing the door is vital for the window to perform correctly (I expect the door-closed nipple is key to this).
I didn't, and the window would wind all the way down but would only go about a third of the way to the top. I had horrible thoughts of having to open everything up again and reseat the motor in the spooling mechanism, but I re-read the guide, closed the door and hey presto
