Why does the air only come out at the windshield vents but none of the other vents when selected?

Chances are your system uses vacuum controls to run the mode motors, and vacuum has been lost. Look under the hood for a small hard plastic vacuum hose going through the firewall that's cracked or pulled apart. Most systems are spring-loaded to go to defrost mode for safety when vacuum is lost. Your feet might freeze but your windshield will be clear.
