On most cars, heat is produced by the heater core. The temperature setting simply regulates the duct, allowing more or less air to bypass the heater core. Air passes through the system as the car moves, even with no fan,. It's really very simple. Since these cars have standard automatic temp control, things obviously got more complicated than they need to be, especially since the system allows the auto temp control to be disengaged.
