⚠️ Safety & Precautions

• Disconnect the negative battery cable before unplugging any door wiring. This helps avoid accidental airbag or module faults.
• Be careful around the side airbag area in the door. Do not probe yellow airbag connectors.
• Use trim tools, not screwdrivers, on painted or soft surfaces. Trim tools are plastic pry tools made for interior panels.
• Support the door panel while unplugging connectors so it does not hang by the wiring.
• If the window glass is taped up, make sure it is secure before removing the latch.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the door trim panel

• Use the trim panel removal tool to pry off the trim cover behind the interior door handle.

• Use the 8mm socket to remove any lower door panel bolts.
• Use the trim panel removal tool to release the door panel clips around the edges.
• Lift the panel upward to unhook it from the window ledge.
• Unplug the electrical connectors and set the panel aside.

Step 2: Remove the moisture barrier

• Use your hands and the plastic clip removal tool to carefully peel back the vapor barrier.

Step 3: Disconnect the latch cables and electrical connector

• Use the pick tool to release the door handle cable retainers.
• Unclip the interior handle cable and the lock rod, if equipped.
• Unplug the actuator/latch electrical connector.

• Use the Torx T20 screwdriver if equipped with smaller bracket screws.
• Slide the latch/actuator assembly out through the service opening in the door.

Step 5: Install the new actuator/latch assembly

• Position the new assembly in the door and route the cables the same way as the old unit.
• Reconnect the electrical connector.
• Reconnect the handle cable and any lock rod or linkage clips.
• Install the latch fasteners by hand first, then snug them with the Torx T30 screwdriver.
• Torque to 9 Nm (80 ft-lbs) for latch fasteners unless your replacement part instructions specify otherwise.

Step 6: Reinstall the vapor barrier and door panel

• Press the vapor barrier back into place with the butyl adhesive sealed all around the edge.
• Reconnect all door panel electrical plugs before hanging the panel.
• Hook the top of the panel on the window ledge, then press the clips in place.
• Install the screws with the Phillips screwdriver and 8mm socket.
• Torque to 3 Nm (27 in-lbs) for interior trim screws.

Step 7: Restore power and test the repair

• Reconnect the negative battery cable using the 10mm socket.
• Test the key fob, interior lock switch, outside handle, and inside handle.
• Make sure the door locks and unlocks smoothly.
• Check that the panel sits flush and no clips are loose.
