Parts

• HVAC mode door actuator × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition off and remove key
3. Disconnect negative battery cable and wait 3 minutes for airbag system capacitor discharge
4. Allow HVAC system to cool completely if vehicle was recently operated
5. Ensure climate control is in OFF position

Procedure

1. 1

   Remove lower passenger side trim panel
   Remove the lower passenger side dashboard trim panel by carefully prying out retaining clips using trim removal tools. Start at the bottom edge and work upward. Remove any visible Phillips screws securing the panel, typically 2-3 screws along the bottom edge. Gently pull the panel away from the dash to release remaining clips.
2. 2

   Remove passenger side knee bolster
   Locate and remove the screws securing the passenger side knee bolster panel (the panel above the footwell). There are typically 4-5 screws. Pull the panel straight out to disengage any remaining clips. Set the panel aside in a safe location.
3. 3

   Access glove box area
   Open the glove box and remove contents. Press inward on both sides of the glove box to release the stop arms, allowing the glove box to drop down fully. Remove the screws securing the glove box assembly (typically 4 screws). Disconnect any electrical connectors for glove box lighting. Remove the glove box assembly completely for better access to the HVAC case.
4. 4

   Locate mode door actuator
   Using a flashlight, locate the mode door actuator on the right side of the HVAC case, behind where the glove box was mounted. The actuator is a small motor with an electrical connector and is typically mounted with 2-3 screws to the HVAC housing. It may be positioned horizontally or at an angle.
5. 5

   Disconnect actuator electrical connector
   Press the locking tab on the actuator electrical connector and carefully pull the connector straight off the actuator. Note the connector orientation for reinstallation. If space is tight, use a small flat blade screwdriver to carefully release the locking tab.
6. 6

   Remove actuator mounting screws
   Remove the screws securing the mode door actuator to the HVAC case. These are typically 2-3 Phillips head screws. Use a stubby screwdriver or extension if needed due to limited space. Keep track of all screws as they are small and easily lost.

7. 7

   Remove old actuator
   Carefully pull the actuator away from the HVAC case. The actuator shaft will disengage from the mode door linkage. You may need to rotate the actuator slightly while pulling to clear the mounting position. Note the position of the actuator shaft and door linkage for proper installation of the new unit.
8. 8

   Prepare new actuator
   Remove the new mode door actuator from packaging. Verify it matches the old unit in appearance and connector type. Do not manually rotate the actuator shaft, as it may need to self-calibrate upon installation. Check that the actuator shaft gear is in good condition.
9. 9

   Install new actuator
   Align the new actuator shaft with the mode door linkage inside the HVAC case. The shaft should engage with the linkage arm. Gently rotate the actuator body if needed to align the mounting holes with the HVAC case. Ensure the actuator is fully seated against the case before installing screws.
10. 10

    Secure actuator and reconnect electrical
    Install the actuator mounting screws and tighten to specification in a cross pattern to ensure even seating. Reconnect the electrical connector to the actuator, ensuring the locking tab clicks into place. Verify the connector is fully seated.

11. 11

    Reinstall glove box assembly
    Position the glove box assembly back into the dashboard. Reconnect any electrical connectors for glove box lighting. Install the glove box mounting screws and tighten securely. Verify the glove box opens and closes smoothly and that stop arms function properly.
12. 12

    Reinstall trim panels
    Reinstall the passenger side knee bolster panel by aligning it with the mounting location and pressing firmly to engage clips. Install all mounting screws. Reinstall the lower passenger side trim panel by aligning clips and pressing firmly until all clips are engaged. Install any screws that were removed.
13. 13

    Reconnect battery and initialize system
    Reconnect the negative battery cable. Turn the ignition to ON position without starting the engine. The new actuator should self-calibrate, which may produce clicking or whirring sounds for 10-15 seconds. This is normal operation as the actuator learns its full range of motion.

Reassembly

1. Ensure all trim panels are properly clipped and secured with no gaps
2. Verify glove box operates smoothly and latches properly
3. Check that no tools or parts were left in the dashboard area

Verification

• Start the engine and turn on the climate control system
• Test all mode positions: defrost, vent, floor, and combination modes
• Verify airflow comes from the correct vents in each mode
• Listen for any unusual clicking or grinding noises from the actuator during mode changes
• Confirm smooth transitions between all airflow modes without hesitation
• Verify no air leaks are present around reinstalled panels
