#	Part	Qty	What it does
1	Blower Motor	1×	Electric motor coupled to a centrifugal fan wheel that moves air through ducts, heat exchangers, or filters.
2	Evaporator	1×	Finned heat exchanger in which refrigerant boils, absorbing heat from the air passing over it to cool and dry the cabin.
3	PTC Heater Core	1×	Electric PTC heater whose self-regulating ceramic elements warm the cabin air without engine heat.
4	Cabin Air Filter	1×	Pleated particle or activated-carbon filter that cleans the air entering the cabin ventilation system.
5	HVAC Actuator	3×	Small geared motor that moves the blend, mode, and recirculation doors inside the heating and ventilation unit.
