one is the fresh air flap near the floor. if it is broken you won't get much air flow there. the other is the air distribution system in the dash all vacuum driven. with the engine OFF... rotate the knob with all the arrows on it... you should hear a psssst noise with each movement of the knob. if you don't you may have a vacuum supply problem. their is a vacuum line that starts on the drivers side "T" off near the intake plenum and crosses to the passenger side just under the lip below the wiper blades. make sure it's working and that it plugs into the plastic canister in the cavity just infront of and below where the door hinge pins are. sometimes the line comes off... sometimes the plastic canister leaks.
