I had the same problem and read through different forms and when I went under the hood - the vacuum line actually disconnected - put it back on and everything works great - thanks so much for your help

The flow direction is accomplished with vanes that are dependent on engine vacuum to operate. You may have a hose off or cracked so the vanes are not answering to the settings you choose.

You have a vacuum leak. Look under the dash and check the placement of the vacuum hoses that activate the vent doors. One or more may have slipped or may be cracked.

This is a vacuum problem. Look under the hood while the car is running and listen for a hissing sound. There could be a vacuum line that came off by the passenger side firewall.
