There's a vacuum hose that goes from the intake manifold, through the firewall, to the control panel on the dash board. It's disconnected. When the system loses vacuum it defaults to defrost for safety reasons. HTH. -Jim

There are several doors and vacuum actuators behind the dash. For air to come out of the dash vents you need vacuum at the "mode door" actuator and vacuum at the "defrost door" actuator. This keeps the defrost door closed and, at the same time, directs air to the dash vents instead of the floor (heater) vent. HTH. -Jim
