More info: I pulled the door panel and visually inspected all the harness wires in both doors. Everything looks normal. I tested +12V and Ground continuity in both doors. Everything seems normal.
I have other other symptom (the Trigger wire which goes to the house battery relay) is not turning on. There's an article on GoWesty which suggests that this trigger wire is easy to disconnect by accident if you are looking at the relay/fuse box ( see ) so I went ahead and dropped the fusebox and made sure the wire was connected. It was.
Next, I started the van running, and verified that the KL15 circuit that it's connected to is dead - I believe that when the van is running it's supposed to be at +12V.
You can see the KL15 set of connectors here ¡ª it's the Green colored ones. Note that most of the wires here are blue, which is the traditional color for "+12V when engine is running".
I believe the input to the KL circuit comes from the Alternator (at least on my old Vanagon that was how it worked).
Now I'm back to being suspicious : what if the KL circuit being dead is affecting the power window control module in addition to my house battery relay?
I've been reviewing online circuit diagrams but am not seeing clearly how the KL15 circuit is powered. One would expect there would be a relay and/or some fuses involved?

In response to question #1, the answer is yes: the brown ground wire. If it is faulty, nothing functions in the wire bundle. The terminus is on a bolt welded to the frame under the driver's side dashboard. When my ground wire broke, I purchased a 36-inch piece of 12 gauge stranded wire at Home Depot, spliced it to the farthest location in the driver's door and put the other end onto the bolt.
