This was a long battle. The car needed the following:

- dash sensor
- foam hose from dash sensor to blower chamber
- temperature regulator
- control unit

The ProgRama rebuild came with some interesting troubleshooting tips, which I'll put in a separate post.
Great news!!
FYI, my car is now resting comfortably in a 10x20 storage unit for the winter. I hope that when it emerges from hibernation in the spring, all of my various HVAC repairs are still locked in
Looking forward to seeing the Programa tips.
Take care.
Mike
