Everything works now. Vacuum is a good thing when it is available!
It is nice to have all the vacuum lines hooked up under the hood.
The problem was in the drivers rear door vacuum actuator. It has a pin hole in the diaphragm. All the locks now work like they are supposed to and the thing holds vacuum for a long time. The car has been sitting for a few hours now and I went out and ran the locks through 5 times. No problem... I took apart the door lock actuator and found a pin hole along the long axis of the diaphragm. I'm going to try and patch that with an inner tube repair kit and see what happens. I'll order a new one if it does not work.
I also cleaned out all the door drains, lubed the door checks, lubed the window slides and installed new vapor barriers on all the doors while I was inspecting things.
I also did some checking under the dash and found 3 of the vacuum elements had torn diaphragms. I removed the bad ones, plugged the lines and safety wired "open" the necessary A/C controls so I can still run the air. It is getting hot down here.
Can you buy just the rubber diaphragms? Or do you have to buy the whole damn thing. It looks like they made them easy to remove, take apart and service, if needed.
