Take a look underneath your dash for any disconnected or damaged vacuum hoses. You likely have a vacuum leak that is keeping the vacuum driven motors that turn the doors inside your dash for ventilation control from working.

Check the three way tee on the firewall. You will find it following the vac hose from the cruise servo check for leaks.
