Hi Gary.. Thanks.. That is about the switch and rebuilding them , which is good stuff ! Been there !
You can see the vacuum nipples etc but he does not get into what each one does .. If left undisturbed you never need to . I have seen a diagram long ago with hose colors and "pin out" of the vacuum plug side of it .
And what each one does ..like fresh air open , fresh air close etc .
It will turn up !! It is there for Ac , and not the more common heater only version .
