My AC is blowing out of the floor vents and the windshied vent nno matter which position the control switch is in. I have traced the problem to no vacuum to the control switch. Can anyone tell me what color the feeder vacuum line is and is there a vacuum canister iin line between the accessory vacuum outlet on the intake manifold and the control switch? It is a 95 Firebird with a 3.4L V6.
