'90 Suburban a/c air vents & switch question..?
I just got the a/c on our '90 Sub repaired (compressor and all) and I noticed that when the a/c switch is in the "Normal" position, that the air flow still comes out as if the switch were on "Bi-level"....about 50/50.
Where do I need to start, or what do I need to do to get all/most of the air to come out of the dash vents when the switch is on "normal" ?
BTW - Defrost works fine as does the "max"...Semper Fi :fighting0037:

Your bi-level setting I am guessing isnt for the air, just cool or heat and your normal and max setting is specifically for ac, so this is by design, max is full ac.

My 85 chev truck only had normal and max for he ac so i am guessing one of the blend doors is not moving correctly
