A little help?

[22Chieftain]

New to the forum, first post. I recently picked up an '88 Chieftain, p30 chasis, 454 carbureted engine, 22'er. Okay, I've noticed that the vent selector is not working and air only blows from the defrost. There are two vacuum canisters under the hood. One for cruise control and the other for HVAC. There is one hose missing from each and I'm not sure where they come from or go to . Air blowing from defrost with A/C selected is cold, but it would be very nice if it would blow from the vents, lol. I have two questions: Where should I start? And is it possible to just bypass the vacuum operated actuator and just set it to blow from the vents manually? Thanks in advance for any help.

If I remember there are cables that change the distribution by moving a deflector plate. First check that they are moving the deflector is moving. Secondly make sure the hoses to the upper vent outlets are attached and intact.

Where is the plate located?

Oh boy I don’t remember where the distribution box was, either inside cab under dash area or in the front under the hood. I had a 1992 Pace Arrow same P30 chassis and engine combo.

Can anyone point me to the distribution box?
