The actuator behind the glove box is in working condition, however, when I turn on the heat, I can feel the warm/hot air blowing on my side(drivers) but it is freezing on the passenger side of the vehicle. What else could be the problem?

The battery died on the car and needed to be replaced. I jumped the Buick and when it started running again the air ac air flow would only come out of the defrost vents. The dash and floor vents aren't working now.

Air sometimes will not come out the vents, only the floor. Stop car, restart seems to help sometimes. Have replaced the vacuum manifold, but problem appears to be in actuator for the door which diverts air to vents or floor.

The control unit and door actuators failed and dealer replaced them. I'm still not sure that all door actuators are working right, as the vent on the outside passenger side blows quite a bit different heat than the middle passenger vent. It has individual heat control for the passenger side, but I don't think that is the problem since the two vents to the passenger side both blow different temperatures.
