NOTE: If a rubber seal on the recirculation air-door is deformed or damaged, the air-door must be replaced.
1. Install the recirculation-air door (3) into the two halves of the air inlet housing (6 and 7). Align the air door pivot shaft with the holes in the
housing halves.
2. Carefully install the two halves of the air inlet housing together and engage the three plastic retaining tabs. Make sure the retaining tabs are fully
engaged.
3. Position the recirculation door actuator (4) to the air inlet housing. Make sure the actuator output shaft is properly aligned to the recirculation door
pivot shaft. If necessary, rotate the actuator slightly to engage the splines on the output shaft with those in the pivot shaft.
4. Install the two screws (5) that secure the recirculation door actuator to the air inlet housing. Tighten the screws to 1.2 Nm (10 in lbs.).
NOTE: If the foam seal on top of the air inlet housing is deformed or damaged, it must be replaced.
5. Inspect the foam seal (1), especially along the parting line (2) of the two halves of the air inlet housing. Replace the seal if it is deformed or
damaged.
6. Install the air inlet housing (3) onto the HVAC housing (2).
7. Install the HVAC housing assembly.

CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C refrigerant system. Failure to properly adjust the refrigerant
oil level will prevent the A/C system from operating as designed and can cause serious A/C compressor damage.
NOTE: When replacing multiple A/C system components, refer to the Refrigerant Oil Capacities chart to determine how much oil should be added to
the refrigerant system.
