The purpose of the air distribution system is to route air to the designated registers. This is accomplished when air enters the plenum through the fresh air inlet and is routed to the selected outlets by use of distribution doors. The pollen filter is located underneath the cowl panel and cleans the air of pollen and dirt particles.
The panel registers are adjustable and are used to aim the discharged air to a required area. The footwell vents, side window vents, and defrost nozzles are non - adjustable.
The distribution door positions are determined by the control components. The distribution doors open and close air flow passages inside the air distribution system to establish air flow direction. There are two distribution doors inside the plenum assembly, defrost vent/duct blend door and footwell vent/duct blend door. The defrost vent/duct blend door can be positioned to either block off or allow air to the panel ducts or defrost ducts. The footwell vent/duct blend door can block off or allow air to the panel/defrost ducts or the footwell duct.
