What a fun day! OK not really. I managed to get the passenger door lock installed and working, something that eluded me last time. Then I put the side glass in and tried rolling it up, and the cables were binding on the winding drum so it would not go up more than halfway.
Recognizing that the previous installation was not done properly**, I had to take it out. The drum that has the cable windings on it was a total mess, a rat's nest of tangles. I spent about 90 minutes*doing random stuff to it like un-looping cable, not fully knowing what I was doing. But in the end I got the drum wound properly - one end of the cable on one side of the drum and the other end on the other, with five windings of cable over the drum in between. Holding it carefully I reinstalled it in the door and then installed the glass again (1 hour's work there) and it works!
Driver's door next.....
