What would cause the windshield on a 2003 Pontiac Sunfire not to defrost?

Defroster vents might be plugged, but I imagine you've already checked that. It's probably a problem in the HVAC system like a loose or broken wire or a loose or cracked hose. It sounds like you might have to pull the shrouds or panels off from around the heater/ac controls to get at them, then remove, inspect, repair or replace. You should probably pick up a Chilton or Haynes manual. let us kow if you need more help.
Another thought:
If your AC is not working, your defrosters probably won't work either, as the AC is automatically switched on when you turn on the defroster.
