Tools required

Parts

• Recirculation door actuator × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and turn off ignition
2. Disconnect negative battery terminal and wait 90 seconds
3. Allow HVAC system to cool if vehicle was recently operated
4. Set front passenger seat to full rearward position for working space

Procedure

1. 1

   Remove glove box
   Open the glove box fully. Squeeze the sides of the glove box inward to release the dampener arms from their stops. Lower the glove box completely and disconnect the glove box light electrical connector if equipped. Remove the glove box by pulling it free from the mounting points.
2. 2

   Remove lower instrument panel cover
   Locate the lower instrument panel cover on the passenger side beneath where the glove box was mounted. Remove the push-pin clips securing the lower cover using a trim removal tool. Carefully pull the lower cover away from the dash, working from bottom to top. Disconnect any electrical connectors for courtesy lights if present.
3. 3

   Access HVAC unit
   With the glove box and lower cover removed, you now have access to the passenger side of the HVAC unit. Use a flashlight to locate the recirculation door actuator on the left side of the HVAC housing. It is a small rectangular motor with an electrical connector and typically 2-3 mounting screws.
4. 4

   Disconnect actuator electrical connector
   Locate the electrical connector on the recirculation door actuator. Press the locking tab on the connector and carefully pull it away from the actuator. Note the connector orientation for reinstallation. If the connector is difficult to reach, you may need to work from different angles or use a small extension.
5. 5

   Remove actuator mounting screws
   Remove the mounting screws securing the recirculation door actuator to the HVAC housing. These are typically Phillips head screws. Keep track of screw locations as they may be different lengths. Support the actuator while removing the final screw to prevent it from falling into the dash.

6. 6

   Remove old actuator
   Carefully rotate and pull the actuator away from the HVAC housing. The actuator shaft engages with the recirculation door, so you may need to rotate it slightly counterclockwise while pulling to disengage. Remove the actuator through the glove box opening. Inspect the door linkage for any damage or obstruction.
7. 7

   Prepare new actuator
   Unpack the new recirculation door actuator. Before installation, manually rotate the actuator shaft to ensure it moves freely through its full range. Compare the new actuator to the old one to verify correct replacement part. Note the position of the actuator shaft on the new unit.
8. 8

   Install new actuator
   Align the new actuator shaft with the recirculation door linkage inside the HVAC housing. You may need to rotate the actuator shaft to align with the door mechanism. Gently push the actuator into position, ensuring the shaft fully engages with the door. The actuator should sit flush against the HVAC housing mounting surface.
9. 9

   Install actuator mounting screws
   Install the mounting screws finger-tight first to ensure proper alignment. Once all screws are started, tighten them in a cross pattern to the specified torque. Do not overtighten as the HVAC housing is plastic and can crack.

10. 10

    Reconnect electrical connector
    Reconnect the electrical connector to the new actuator. Push firmly until you hear or feel the locking tab click into place. Gently tug on the connector to verify it is secure. Ensure no wires are pinched or stretched.
11. 11

    Reinstall lower instrument panel cover
    Reconnect any electrical connectors for courtesy lights if they were disconnected. Position the lower instrument panel cover and press firmly to engage the push-pin clips. Ensure all clips are fully seated and the cover is flush with the surrounding dash.
12. 12

    Reinstall glove box
    Reconnect the glove box light electrical connector if equipped. Position the glove box into the mounting points and push until it clicks into place. Ensure the dampener arms are properly positioned. Open and close the glove box several times to verify proper operation.
13. 13

    Reconnect battery and initialize system
    Reconnect the negative battery terminal. Start the vehicle and allow the HVAC system to perform its self-calibration routine. You may hear the actuator cycling through its range during this process. This typically takes 30-60 seconds after ignition on.

Reassembly

1. Ensure all trim panels are securely fastened with no loose clips or gaps
2. Verify glove box dampeners function properly and the box opens and closes smoothly
3. Check that no tools or parts were left in the dash cavity
4. Confirm all electrical connectors are fully seated and locked

Verification

• Start the vehicle and turn on the HVAC system
• Toggle the recirculation button on the climate control panel and verify the indicator light responds
• With fresh air mode selected, verify you can feel outside air entering the cabin
• Switch to recirculation mode and verify airflow changes character and outside air intake reduces
• Listen for any clicking, grinding, or buzzing noises from behind the dash that might indicate binding or misalignment
• Test both automatic and manual climate control modes if equipped to ensure proper actuator response
• Verify no warning lights or HVAC fault codes are present on the instrument cluster
