A very basic answer is: The hot water the engine produces is circulated thru the heater core. The heater core looks like the autos radiator only smaller. The heater core is located inside the heater box. So as the engines hot water circulates thru the heater core the heat will transfer into the heater box. As long as the engine is running and everything is working properly the heater core will stay hot inside the heater box.

Really long bolts go through the heater core/blower motor housing into the cab. You have to go through the dash and undo the nuts and the housing will come off the front of the firewall in the engine bay. Once the housing's removed, it has a cover/bracket that has to be unscrewed around the perimeter of the housing to release the heater core.
