The air distribution knob only blows air through the defroster vents, no matter what other

The directional vents are vacuum controlled ... There are at least 2 or more vacuum actuators and one selector switch. The selector sw is both electric and vacuum ... it sets the output air to the desired location ... upper,lower, defrost etc With the radio off and the blower on slow ... rotate the directional switch and you should hear the baffles changing ... confirm that they changed with the air .... if nothing changes then you have either a small plastic tubing off or the switch is bad. If the tubing is off you will probably notice the engine running rough
