GENERAL

The air distribution and filtering system controls the distribution and quality of air supplied to the vehicle interior. The system consists of

1. Air ducts.
2. Air registers and vents.
3. A cabin air filter.

AIR DUCTS

The air ducts distribute the air from the heater to the various registers and air vents around the vehicle interior. The air ducts for the instrument panel registers, the driver lap register and the second row registers are connected to the heater outlet manifold on top of the heater. The air ducts for the front and second row footwells are connected direct to outlet ports on the heater. The air ducts for the windshield vents and the side window vents form part of the structure of the instrument panel.

AIR REGISTERS AND VENTS

The air registers allow occupants to control the flow and direction of air from the air ducts. The driver lap register has moveable vanes to regulate the flow and direction of the air. The instrument panel and second row registers each have a thumbwheel to regulate flow, and moveable vanes to control direction.

The air vents are fixed outlets either integrated into the end of the air duct or installed in the trim panel connected to the air duct.

Scheme 2

The cabin air filter is a combined pollen and odor filter installed in the air inlet duct. The filter removes particulates and unpleasant odors from the fresh and recirculated air entering the blower.

OVERVIEW

The air distribution and filtering system is a fairly straightforward design requiring no specialized techniques for diagnosis.

INSPECTION AND VERIFICATION

1. Verify the customer concern.
2. Visually inspect for obvious mechanical faults. Mechanical Air ducts Air registers/vents Pollen filter (blocked/contaminated) For the most part, faults will be confined to blocked or damaged registers or blocked vents. Check for foreign objects finding their way into vents and registers and rectify as necessary. There is a self-test procedure for the motors and flaps controlling the air flow to the registers: REFER to: «Climate Control System»(/land-rover/range-rover-sport/i-2005-2009/remont/hvac/#climate-control-system-general-information) information.
3. Use the approved diagnostic system or a scan tool to retrieve any diagnostic trouble codes (DTCs) which may have been set as a result of a blocked or damaged flap. For a list of DTCs relating to the climate control system: REFER to: «Climate Control System»(/land-rover/range-rover-sport/i-2005-2009/remont/hvac/#climate-control-system-general-information) information. Make sure that all DTCs are cleared following rectification.

The pollen filter must be replaced at the specified intervals to make sure the operation of the system is not affected.
