What year?

On many gm's there's a vacuum resoirvoir on the drivers side, mounted
to the hood. It's a "ball" a bit bigger than a soft ball. Look
carefuly at the hoses coming to this. If one falls off or is cracked,
the a/c system will usually be stuck in defrost - all air comes out
the defrost ducts.

No high air.. do you mean it won't go to recirculate mode? Or the fan
does not change between position 3 and 4?

No recirc would be affectd by a cracked or disconnected vacuum hose
also.

In that case it might cost you.
Climate control, right?
Those boxes ran about $300+ USD last I checked.
I would get under the dash first with a mityvac and test the vac. motor.
