Well I tried to follow Bill R's directions and I think I screwed the pooch..
I was able to pry back the top of the door panel, and I broke off a white plastic piece that the manual lock rod was connected to, but that didn't open the door. After a few minutes I decided to take off the opposite rear door panel to see what I was looking at (should have done this first!). It turns out all I did was break off the pivot arm for the manual lock rod, see pic #1. Looking at the inside of the door in pic #2, I don't see anything that can be done via from the top of the panel with the door in place. This got me thinking that perhaps Bill R's procedure is for the old style (91 or earlier) lock actuators. So I dug out an old actuator (pic #3) and I see how breaking off the white arm could release the lock mechanism. Unfortunately, I have the new style (or e36 style) actuator shown on the right, that mounts directly to the lock mechanism. I believe this fact also negates Shoguns e32 directions posted in the first link.
The only other thing I can think to do and try and remove the door panel with the door in place (don't know if this is possible without damaging the panel) and then remove the actuator from the lock mechanism, while the assembly is still in place. (Don't know if this is possible. Usually you remove the lock mechanism first, but the door needs to be open).
Any other suggestions? If not, I guess I will try and remove the door panel with the door still closed.
Thanks to all....
