Classic problem, the arm that opens the drivers side vent flap has come off one of the joints.
I, like others I understand, have propped open the door, so now you have air coming all the time through that vent, and heat too when called for.
Remove the kick panel, follow the opening near the center, you'll see it. Note that near the center console you have a plastic 90 degree screw.
