You need to see vacuum on the blue hose behind the A/C panel that runs the A/C/Defrost door.
Yours is either stuck in the defrost position closed which would be the no vacuum position or else it's not getting any vacuum.
Feed to the whole A/C control head vacuum is the purple hose so check that first car running for a good vacuum supply.
I don't know if you can manually operatie the door to unstick it however, maybe from the top via the defrost vents with something that will bend around the plenum and still contact the door to unstick it.
3/16" wooden dowel or 1/8" perhaps.
I'd check behind the control head or up under from the radio removed, (or both) for access and check for proper vacuum first.
