I had a similar problem with my '66 and found that the negative was "shared", for a lack of a better term, which interfered with the operation of the courtesy lights. Even though my volt/ohm meter showed 12v in- and correct ground out, the lights just did not work under actual application. I ran a separate ground to/from the switch and the problem was solved. Hope this helps, and sorry I can't detail it other than that. Good luck.

No offense taken and I appreciate the efforts to help. I've owned this one for about 20 years- done most of the work myself. I restored the dash and interior long ago and I know my way around the car pretty good
Some Clarification:
Both door switches are new with the signal wire male connector- correct for 72. I took them both out, - making sure that the single wire is not grounded to the car. This would take any issue with the door switches out of play I believe
I disconnected the headlight switch briefly thinking that the rheostat? that you rotate to turn to dim the instrument lights and turn on the courtesy light is not the problem - thinking it was maybe stuck in the on position
I will try to trace and isolate the courtesy lights wiring thinking that maybe they are grounding out somewhere?

All three interior lights should come on when you open either door. If any of them do when you open the driver's door, the switch is not the problem. The problem will be in the socket that is not working. Opening either door or rotating the dash dimmer switch fully CounterClockwise provides a ground to the white wire from all three interior courtesy lights. The orange wire is always 12 V even with the ignition switch off. The bulb must be a two contact number 90 bulb.
