2. Install the upper defrost/panel-air door (1), lower defrost/panel-air door (2), directional vane (3), rear outlet-air door (4) and the blend-air door (5) into the right side air distribution housing (6) as required. Align the air doors with the pivot shaft holes in the housing.





3. If removed, align the front floor-air doors (1 and 3) with each other and install then into the center partition (2). Make sure that the air door retaining tabs (4) are fully engaged.





4. Install the center partition (3) into the right half of the air distribution housing (2).
5. Install the left half of the air distribution housing (1) onto the right half of the air distribution housing. Align the air door pivot shafts with each other and with the pivot shaft holes in the housing.





6. Install the eight screws (5) that secure the two halves of the air distribution housing (3) together. Tighten the screws to 2.2 Nm (20 in. lbs.).
7. Install the four metal clips (4) that secure the two halves of the air distribution housing together.
8. Inspect the foam seal (1), especially at the parting line (2). If the seal is deformed or damaged, it must be replaced.





9. On LHD models, carefully install the heater core (3) into the right side of the air distribution housing (2).
10. If equipped with dual zone heating-A/C, install the blend door stop (1) onto the right side of the air distribution housing.





11. Position the rear floor/console door actuator (2) onto the right side of the air distribution housing (3). If necessary, rotate the actuator slightly to align the splines on the actuator output shaft with those on the floor/console door pivot shaft. Blend Door Actuator - Installation.
12. Install the screws (1) that secure the rear floor/console door actuator onto the right side of the air distribution housing. Tighten the screws to 2 Nm (17 in. lbs.).
13. If equipped with dual zone heating-A/C, position the blend door actuator mounting bracket (5) onto the right side of the air distribution housing and install the retaining screws (4). Tighten the screws to 2 Nm (17 in. lbs.).
14. If equipped with dual zone heating-A/C, position the blend door actuator (7) onto the blend door actuator mounting bracket and install the retaining screws (6). Tighten the screws to 2 Nm (17 in. lbs.). If necessary, rotate the actuator slightly to align the splines on the actuator output shaft with those on the blend door stop. Blend Door Actuator - Installation.





15. On RHD models, carefully install the heater core into the left side of the air distribution housing (3).
16. Install the front floor door linkage rod (6) and the lower defrost/panel door pivot gear (2) onto the left side of the air distribution housing.
