HVAC Help

[leefybeaver]

All right, so I'm at this again. Found some parts in my buckets. Can someone help me out where the various vacuum lines go. I'm trying to get this system working again. This is the beauty of Saskatchewan in the summer months. You need your heat in the morning and the AC in the evening! in my case, i just want the heat. The heat works but i want to be able to select where it goes in the car. Thanks for the help.

Got it. Purple goes to vacuum tank. Gray goes to heater control valve

I'm guessing I need a vacuum line from the carb/intake manifold into that vacuum tank too?

What G-body had that fancy HVAC control?

That's in my 1984 Regal Limited

Can the system still operate without the heater control valve. I don't have that anymore.

Yes, Plug the hose. The only time the system closes off the hot water valve is during max air conditioning

Big hose goes to intake

Thanks for the help guys. System seems to be working alright. Well better than before. Pretty neat for 1984 to have a thermostatic heater and AC in that car!
