My 96 vette is still having ac blowing problem. The lower and defroster vents are working but not in the face register. After reading some post I replaced the broken vaccuum connections to the manifold $8.00 part and still the same problem. I took it to mechanic and he checked the ac control unit and check the vaccum connections and no problem found. I noticed that when the ac control unit is disconnected and the ac is turn on the ac still blows from the lower and defroster only. Is this normal ? or my ac control unit is defective? What does the ac contol unit do and why is it still blowing from the lower and defroster when disconnected. Is there something else i should be check. How do i check the ac control unit if its defective . It cost $ 300 for the part and I was told that i cant bring it back when purchase because its Electronic item. ANY HELP OR ADVISE IS GREATLY APPRECIATED. THANKS IN ADVANCE.
