• Support the door glass carefully so it does not drop while the panel is removed.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the door trim panel

• Use a trim panel tool to pop off the trim covers around the armrest, door handle, and switch area.
• Use a 7mm socket and Torx T20 screwdriver to remove the visible panel screws.
• Lift the panel upward to release the top edge from the window ledge.
• Disconnect the electrical connectors for the switch pack and any courtesy lights.
• Pull straight out to avoid broken clips.

Step 2: Peel back the vapor barrier

• Use a small flat screwdriver and your hands to carefully separate the vapor barrier from the door shell.
• Do not tear it; you will need it to seal the door later.
• Set it aside on a clean surface.

Step 3: Disconnect the latch and lock hardware

• Use a pick tool and needle-nose pliers to release the lock cable and door handle linkage.
• Use a 10mm socket with extension to remove the latch mounting bolts.
• Support the latch while removing the last bolt so it does not drop inside the door.
• Torque on reassembly: 9 Nm (80 in-lbs)

Step 4: Remove the door lock actuator assembly

• Slide the latch/actuator assembly out through the service opening in the door.
• If it hangs up, adjust the window glass position slightly by hand and use painter's tape to hold the glass up.
• Disconnect the actuator electrical connector before fully removing the assembly.

Step 5: Install the new actuator assembly

• Position the new front door lock actuator/latch assembly into the door.
• Reconnect the electrical connector first.
• Reconnect the lock cable and door handle linkage using needle-nose pliers.
• Install the latch bolts with a 10mm socket.
• Torque to 9 Nm (80 in-lbs)

Step 6: Test the mechanism before closing the door

• Reconnect the negative battery cable.
• Use the key fob, interior switch, and door handle to test lock and unlock operation.
• Confirm the inside and outside handles open the door correctly.
• If the lock cycles but the handle does not work, recheck the cable routing.

Step 7: Reinstall the vapor barrier and door panel

• Press the vapor barrier back into place using the original adhesive or new door vapor barrier adhesive.
• Reconnect all door panel electrical connectors.
• Hang the top edge of the panel on the window ledge, then press the clips in with a trim panel tool.
• Reinstall the screws with a 7mm socket and Torx T20 screwdriver.
• Torque to snug only; do not overtighten plastic trim screws.
