2000 Protege heater works but no defrost

The climate control looks like this:
I think I can tell the selector is electrical. On the receiving end of the harness should be an actuator that operates a door inside the air box. This door is either jammed or the actuator is broken or the circuit is interrupted. That interruption could be caused by a bad switch, a short to ground, a short between wires etc.
A thourough inspection should let you find the culprit.
If it happens to be cable operated it is purely mechanical and you may find a broken plastic piece or detached cable.
Good luck.
