Parts

• HVAC blend door actuator × 1 — Mopar 4886005 or equivalent

Preparation

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

Procedure

1. 1

   Remove lower dash panel
   Working from the passenger side footwell, locate the lower dash panel below the glove box area. Remove the fasteners securing the lower panel (typically 4-6 fasteners along the upper edge and sides). Carefully pull the panel away from the dash structure and set aside. On this platform, check for both visible screws and push-pin clips along the panel edges.
2. 2

   Access glove box area
   Open the glove box door fully. Remove the glove box by locating and removing the mounting screws at the hinge points and side brackets (typically 4 screws total). Disconnect the glove box light connector if equipped. Remove the glove box assembly to expose the HVAC housing behind it.
3. 3

   Locate blend door actuator
   Using a flashlight, locate the blend door actuator on the passenger side of the HVAC housing. The actuator is a rectangular plastic module with an electrical connector and a gear-driven arm that engages with the blend door linkage. It is typically positioned on the upper-right section of the HVAC housing near the evaporator case.
4. 4

   Disconnect actuator electrical connector
   Press the locking tab on the actuator electrical connector and carefully pull the connector straight away from the actuator body. If access is restricted, use needle-nose pliers to depress the tab. Ensure the wiring harness is not under tension and route it clear of the work area.
5. 5

   Note actuator arm position
   Before removing the actuator, observe and note the position of the actuator arm relative to the blend door linkage. This ensures proper installation alignment. The arm should be visible where it engages with the white or tan plastic blend door lever on the HVAC housing.
6. 6

   Remove actuator mounting fasteners
   Remove the 3 screws securing the blend door actuator to the HVAC housing using a 7mm socket or nut driver. These screws typically form a triangular pattern around the actuator body. Support the actuator while removing the final screw to prevent it from falling.

7. 7

   Remove actuator from housing
   Gently pull the actuator straight away from the HVAC housing. The actuator arm will disengage from the blend door linkage. If resistance is felt, verify all mounting screws have been removed and check that the arm is not binding on the linkage. Rotate the actuator slightly while pulling if needed to clear the arm from the linkage.
8. 8

   Inspect blend door operation
   With the actuator removed, manually move the blend door linkage through its full range of motion. The door should move smoothly without binding. If the door is stiff or broken, further disassembly of the HVAC housing may be required to repair the door itself. Verify the linkage arms and pivot points are intact.
9. 9

   Prepare new actuator
   Remove the new blend door actuator from packaging. Verify the actuator arm is in the same approximate position as noted during removal. If necessary, carefully rotate the actuator gear by hand to align the arm position. Do not force the actuator gear or apply power to the actuator outside the vehicle.
10. 10

    Install new actuator
    Position the new actuator with the arm aligned to engage the blend door linkage. Carefully guide the actuator arm onto the linkage lever while positioning the actuator body against the HVAC housing mounting surface. Ensure the arm is fully seated on the linkage before proceeding.
11. 11

    Install actuator mounting fasteners
    Install the 3 mounting screws through the actuator body into the HVAC housing. Start all screws by hand to ensure proper thread engagement. Tighten the screws in a star pattern to 3.0 Nm (2.0 lb-ft) using a torque wrench. Do not overtighten, as the plastic housing threads can strip.

12. 12

    Reconnect electrical connector
    Plug the electrical connector onto the new actuator until the locking tab clicks into place. Gently tug on the connector to verify it is fully seated and locked. Route the wiring harness to avoid contact with sharp edges or moving components.
13. 13

    Test actuator operation
    Reconnect the negative battery cable. Turn the ignition to the ON position without starting the engine. Set the climate control to different temperature settings and listen for the actuator motor operation. The actuator should produce a quiet whirring sound as it moves the blend door. Verify airflow temperature changes from hot to cold as temperature settings are adjusted.
14. 14

    Reinstall glove box assembly
    Reconnect the glove box light connector if equipped. Position the glove box assembly into the dash opening and install the 4 mounting screws at the hinge points and side brackets. Verify the glove box opens and closes smoothly without interference.
15. 15

    Reinstall lower dash panel
    Position the lower dash panel into place below the glove box area. Install all fasteners (screws and push-pin clips) along the upper edge and sides to secure the panel. Ensure the panel is flush with the surrounding dash structure and all mounting points are secure.

Reassembly

1. Reassembly follows removal in reverse order
2. Verify all electrical connectors are fully seated and locked
3. Ensure no tools or fasteners were left in the dash area before closing panels

Verification

• Start the engine and operate the HVAC system through all temperature settings
• Verify hot air is produced when temperature is set to maximum heat
• Verify cold air is produced when temperature is set to minimum cooling
• Listen for smooth actuator operation without grinding or clicking noises
• Confirm no air leaks from unsealed ducting or panel gaps
