This is a scanned page (HA-3) from a Nissan factory service manual section titled "AIR FLOW AND COMPONENT LAYOUT." The page presents an exploded-view diagram labeled "Component Layout" showing the heating/ventilation (HVAC) ductwork and components behind the instrument panel. Labeled components include the defroster nozzle, two side ventilator ducts, two defroster ducts, the center ventilator duct, the heater unit, the control assembly, the control finisher, the heater duct, and the intake box. Items marked with an asterisk (defroster nozzle, side ventilator ducts, center ventilator duct, heater unit) carry the footnote "For removal, it is necessary to remove instrument assembly," telling the reader that the dashboard/instrument assembly must be pulled to access those parts. The diagram carries the illustration reference code RHA002 and the page number HA-3, consistent with the Heater & Air Conditioner (HA) section of a Nissan service manual. A reader can learn how the interior HVAC air distribution parts fit together, what each duct is called, and which components require removal of the instrument assembly before they can be serviced or replaced. The document does not state a specific model year, model name, or part numbers.
