I have finally got all my 69 GTO Heater/AC Box doors working and need to know if when you put the control to bi-level does the upper AC Door open and the lower door close or vice versa. I have spent numerous hours with my service manual and on my back on the floorboard tracing out and replacing vacuum lines and a reply would be greatly appreciated.
