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 N.m (10 in lbs.). 

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. 

NOTE:

If a rubber seal on the recirculation air-door is deformed or damaged, the air-
door must be replaced.

NOTE:

If the foam seal on top of the air inlet housing is deformed or damaged, it 
must be replaced.

CAUTION: Be certain to adjust the refrigerant oil level when servicing the A/C 

refrigerant system. See REFRIGERANT OIL LEVEL. 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. See REFRIGERANT OIL LEVEL.

NOTE:

If the A/C evaporator is being replaced, add 60 milliliters (2 fluid ounces) of 
refrigerant oil to the refrigerant system. Use only refrigerant oil of the type 
recommended for the A/C compressor in the vehicle.

NOTE:

LHD model shown in illustrations. RHD model similar.
