ZR-1 Net Registry Forums - View Single Post - Has anybody ever replaced the HVAC Programmer?

Progress!! The problem with the air flow controls is now working correctly. I never did get the HVAC Programmer out, but I was able to apply a vacuum source to each controller and they all worked. Then I determined that the vacuum tubing between the plenum and the Programmer may have been kinked behind the Passenger side hush panel.

Now I need to get the "Air Mix Door" synced so that it stops giving heat when AC is requested.

BTW, I have never gotten any trouble codes on the Control unit.
