    Actually it blows out the mid vent for a bit then goes to defrost and floor. Stays that way for a long time then it goes to the mid vents for a bit then back to floor & defrost.

SOURCE: 98 Olds LLC - AC works but fan air does not blow

If you have a late model GM car and the system is controlled electronically the blend door actuator becomes weak. When this situation occurs it will not move the air direction door inside of the heater/air conditioner plenum. in your case not to the vents Replace the actuator with new and recheck the system. i hope this helps

AC is only blowing through the defrost vents in the dashboard?


I think your problem is the head unit that selects where the air comes out ie. Face, floor, defrost, or hi-level face and floor. If that's not working then it will not let you switch location that you want the air to come out.

Dash vents will not blow air. Defroster and floor vents blow fine.


Is it a new vehicle? I had a new vehicle that had the same problem. Answer was that the holes weren't punched out of the vent.
