For as long as I can remember, the air vent left of the steering wheel has always let in air, no matter where I have the little "Vent - A/C" lever below it. The vent lets in air when the lever is on "vent", "A/C" or in the middle. I usually have to keep the vent directional guard all the way closed so I don't get a blast of cold air. However, when I turn on the heater, heat does come through the vent. I'm thinking that maybe the little blocker that I imagine blocks either the vent or the AC/heater depended on the lever is broken? Any ideas? Its gettin' cold in my car and I don't want to turn the heater all the way up or else my car won't make it up the hills!

i think you have hit it right on the head. i dont remeber how they work, if its a direct lever or a short cable. But that is what the problem is.

IIRC, when I had the dash out of my 85 twagon, there was a short stiff wire from the flapper handle to the actual flapper. You may be to contort yourself into weird positions and get a good look up under the dash to see where it is. It probably isn't connected.
