Your truck's heater core is very similar to a radiator, only smaller. When in use, the control valve allows a portion of the engine coolant to circulate through the heater core. As blower fan passes air over the core it is heated up for circulation into the cabin to provide warmth to the occupants. This is how a properly functioning heater core works in your system.
