I have a '99 Buick Regal that is doing the same thing. I have heard that there is a servo motor under the dash the controls the vent door and that this may be the problem. I have not been able to find out much more. There is a vacuum box under the dash and it is working fine. The control system seems to be working fine too.

I have the same problem with a 93 Buick Park Avenue it seems to happen whenever the battery goes dead from leaving the lights on or some other cause. Also have seen threads about this when battery is replaced. I usually only notice it when it is cold outside. One side is hot and one side is cold? dual climate control? Also what happens is sometimes if not all the time the temp guage might flash on the control panel, that is what is moving the damper. If you shut off the car and turn back on the car it will blow hot on both sides and then the damper moves again. Seems to be a common problem and there was a reset I had that would sometimes by hitting buttons give hot air but what it does it moves the dampers back where they are supposed to be but then it went out of sync again and cleared up in the summer for some reason, but left the lights on and now it is doing it again. Leaving the lights on and battery going dead did it for me? Anyone else?
