Air Conditioning

Charged my system with Freeze12 yesterday. Low side reading 40psi and high side was 220 psi. Took it just the way it should but I am blowing 120 degrees from my vent. Lines were very cold. Thinking the doors are not moving to bring the cold air in. Anyone have some information on how the control system works before I start digging into the dash? Is it vacuum actuated? thanks

How do your brakes work? Are you getting vaccum to the controls? The doors and such are vaccum controlled, but you say it's blowing out the vents just hot, on my 84 the "blend" door is behind the glovebox and is cable controlled, but you could start looking there
