SOURCE: There is no air flow
You need part GM Part number 89018675 or ACDelco 15-73596. The Mode Selector Actuator. What happens is the part is a CHEAP part POORLY designed and when it goes to turn the flaps inside the HVAC unit its the plastic gear slips instead of turning the flap!!!
Just to forward you you might want a deal to install this art for you unless your good at fixing your own vehicle, because you need SMALL sockets and a lot of patience to get this part in!!!
The part is ALMOST directly above the steering shaft for your steering wheel, so theres a lot you got to remove before you will even see them!!!
I only recommend you to have a dealer put this part in for you, unless you have your own service manual!!
Because there is 5 of these darn things and if you pick the wrong one you will have to do it all over again!!!
3 on the Drivers side and 2 on the Passengers side!!
But replacing this part SHOULD solve all your problems!! AS it did for me and i was having the same issues as you have described!!

99% of the time when they do that it is the control head. that is the thing you adjust all your temp settings on. have to purchase from dealer. have last eight digits of vin # when ordering.

common problem, check under dash by the gas pedal if control arms are muving went selecting from ac to heat cuz this it is the control for the vents to go from ac to heat and to defrost.

There is a thin vacuum hose running across the top of the engine from the front left side to the rear. this connects to the back of your a/c position switch. Over time it becomes brittle and cracks therefore leaving your vents stuck in it's last positon. Cut out the bad section and purchase about 3 feet of rubber hose at the auto store. Take a piece of the bad section with you to see which size hose will fit onto it. Slip it over the cut ends and pass it thru the space where the windshild washer fluid hose is attached to the back wall. This will keep it up and away from the heat. I had this problem on a 1997, 1999 and 2002 Astro and fixed the problem for less that $3.
