The heater in my '02 Pathfinder works fine when moving, yet when stopped at a light, cold air blows out. Within 10 seconds of moving again, the hot air returns. What could be going on?

Low coolant/air in cooling system.  
Take it to a shop, and have them flush and bleed your cooling system, and all will be fine.
