I own a 1970 SS396 with factory a/c. When I turn the a/c on half of the air blows out of the dash vents and half out of the floor. Could it be a vacuum actuator problen or maybe the vacuum itself? Maybe the mechanical linkage is froze up? Does anybody have any suggestions?

Do you have the "bean can" or "spaceship" vacuum container on the side of the evap box that is closest to the engine? If not, that could be the problem. When it does this, will it all blow thru the dash at idle and switch over on accel?
