Re: Heater and a/c vacuum lines
You need one of those hoses to go through the firewall and connect to a round(ish) pint sized canister on the engine side of the firewall. That is where the system gets the vacuum to operate. The canister also needs a connection to manifold vacuum.

Tagging for comments. My blend door on my 83 isn't working anymore after swapping in a new A/C control. I replaced the plastic bit that breaks with a billet clip while I had it apart so I know it's not that.
