Damper/flap for driver's side is probably stuck. Try moving the selector from cold to hot several times. Also, move the recirc/outside air control if the previous doesn't work.

i had the exact problem with my 2002 pontiac grand prix. i found a broken vacuum line that comes off the back of the engine. this vacuum line runs down the passenger side top wheel well in the engine compartment. it goes behind the battery mounts then traverses into the big wire harness just below the battery. the vacuum hose was broken there under the battery so i couldn't see it without physically tracing where it went. i took a little piece of rubber hose about the diameter of an aquarium hose and reconnected the hose. i now have cool air. you have to remember that this little vacuum hose keeps the climate control does open as well as close them depending on your hot-cold settings. this all occurs from the climate control knob inside the car. hope this helps. a real easy fix too...........phil
