That is a very common problem on our cars. They used a VERY tiny vacuum line to run to cycle the vents. It originates at the vacuum tree behind the drivers side strut tower at the firewall, and runs along the firewall. It will be cracked/broken somewhere. I guarantee this is your problem.

To fix it, I take a piece down to a hobby shop, get some hollow tubing that fits very snug inside the vacuum line, cut a piece off and use it as a butt connector to joint the two pieces where it broke. You should tape it up too when you are done.
