If you encounter similar situation, you may want to open the unit up and see. an hour of labor saved me $$$
here's a photo of the printed wiring board

Where do you find this -- is this inside the door panel?

seningen,
The pwb is in the door lock mechanism. The harness connector attaches to a mating connector that is soldered to the PWB.
I was going to buy a new mechanism, so decided to take it apart. For my car, this was the root cause.
If you plan to take it apart, be aware of jigsaw puzzle-like assembly of the door mechanism.
I think the original message has some photos and here's one of the broken solder joint
