This procedure covers replacement of the recirculation door actuator in the HVAC system, which controls fresh air vs recirculated air flow into the cabin.

Warnings

Tools required

Parts

• Recirculation door actuator × 1 — Toyota 87106-02240 or equivalent
• Panel retaining clips (if damaged) × 5 — Toyota 90467-07211 or equivalent

Preparation

1. Park vehicle on level surface and turn off ignition
2. Allow HVAC system to cool if recently operated
3. Disconnect negative battery terminal and wait 3 minutes for airbag system to discharge
4. Set front passenger seat to its rearmost position for working room

Procedure

1. 1

   Remove glove box
   Open the glove box fully. Locate the two damper arms on either side of the glove box that limit opening range. Squeeze the sides of the glove box inward to release the stoppers from their slots, then lower the glove box past its normal stop point. Disconnect the glove box light connector on the right side. Remove the three screws securing the glove box hinge at the bottom, then remove the glove box assembly completely.
2. 2

   Access HVAC housing
   With the glove box removed, you will see the white/beige HVAC housing. Identify the recirculation door actuator on the left side of the housing - it is a small rectangular motor with a gear mechanism and 3-wire connector. Use the flashlight to confirm its location and check for the mounting screws.
3. 3

   Disconnect actuator electrical connector
   Locate the 3-wire electrical connector attached to the recirculation door actuator. Press the locking tab on the connector and gently pull straight out to disconnect. Do not pull on the wires themselves. Note the connector orientation for reinstallation.
4. 4

   Remove actuator mounting screws
   Remove the three Phillips head screws securing the actuator to the HVAC housing. These screws are located around the perimeter of the actuator body. Keep track of these screws as they may be difficult to retrieve if dropped in the confined space.

5. 5

   Remove old actuator
   Carefully pull the actuator straight out from the HVAC housing. You may need to wiggle it slightly to disengage the gear from the door linkage. The actuator shaft has a gear or lever that connects to the recirculation door mechanism - note its position before complete removal.
6. 6

   Inspect door mechanism
   With the actuator removed, use the flashlight to inspect the recirculation door linkage visible through the mounting hole. Check that the door moves freely and is not broken or obstructed. Manually rotate the linkage to verify smooth operation throughout its full range of motion. Clean any debris from the mounting surface on the HVAC housing.
7. 7

   Install new actuator
   Position the new recirculation door actuator with its gear aligned to the door linkage visible in the mounting hole. The actuator will only install in one orientation. Gently push the actuator into place, ensuring the gear fully engages with the door mechanism. You should feel it seat properly against the housing.
8. 8

   Secure actuator mounting screws
   Install the three Phillips head mounting screws through the actuator into the HVAC housing. Hand-tighten first to ensure proper alignment, then torque to specification in a crossing pattern to ensure even seating. Do not overtighten as the housing is plastic.

9. 9

   Reconnect electrical connector
   Reconnect the 3-wire electrical connector to the new actuator, ensuring it clicks into place securely. Verify the locking tab is fully engaged. Gently tug on the connector to confirm it is locked.
10. 10

    Reinstall glove box
    Position the glove box assembly and align the hinge at the bottom. Install the three hinge screws but do not fully tighten yet. Reconnect the glove box light connector. Raise the glove box to its normal operating position and squeeze the sides inward to clear the damper stops, then release to allow the stops to engage. Verify smooth operation, then fully tighten the hinge screws.
11. 11

    Reconnect battery and initialize system
    Reconnect the negative battery terminal. Turn the ignition to ON position without starting the engine. The HVAC system will perform a self-calibration cycle - you will hear the actuators moving through their full range. This may take 30-60 seconds. Do not interrupt this process.

Reassembly

1. Ensure all electrical connectors are fully seated and locked
2. Verify glove box dampers engage properly and glove box opens and closes smoothly
3. Check that no tools or screws were left in the HVAC housing area

Verification

• Start the engine and turn on the HVAC system
• Press the recirculation button on the climate control panel and verify the indicator light illuminates
• Listen for actuator operation - you should hear a brief motor sound when switching modes
• With the system in recirculation mode, check that airflow is noticeably reduced or stopped at the cowl fresh air intake (have a helper place their hand near the intake grille below the windshield)
• Switch to fresh air mode and verify airflow resumes at the cowl intake
• Cycle between recirculation and fresh air modes 3-4 times to confirm consistent operation
• Verify no rattling or unusual sounds from behind the glove box area during operation
