Why do the dash vents not work but the defrost does on 1985 camaro?

The vent selection is controlled by a stiff wire that pushes or pulls mechanical flaps inside the dash to channel the air. If you can't control the air flow it could be that the cable is detached on either end, or that one of the flaps inside/underneath the dash is broken or jammed. If your selector lever moves smoothly, it's likely that your cable has become disconnected. If the selector jams, it's probably a flap and will need some dashboard disassembly.

If the floor and defrost vents are both operating and you can't change air flow to any other vents, the dash control unit does not have a vacuum source. This vacuum comes into the cabin from under the hood. Look for a black plastic line coming through the firewall near the blower motor on the passenger side. This line should attach to a vacuum canister. The canister is generally round black plastic. What usually happens is the vacuum hose gets knocked off or the plastic line may break.
