I have a 92 PA, and the main vacuum line comes from the engine and goes through the fire wall. Mine had become disconnected and all heater and A/C functions did not work properly. You might check to see if this is connected.

There is a vacuum problem to the internal vent control assembly. Either a vacuum leak, missing hose, or blocked vacuum port is not allowing vacuum to reach the ports of the door controls that direct air flow inside the HVAC box under the dash. Check for vacuum at the control assembly, and then that the assembly is porting the vacuum to the control pods.
