⚠️ Safety & Precautions

• Disconnect the negative battery cable before removing the door panel. The door has a side airbag system.
• Wait at least 90 seconds after battery disconnect before working in the door area.
• Keep all screws and clips organized. Door panel clips can break if pried too hard.
• Support the door trim panel while unplugging switches so you do not stress the wiring.
• Do not close the door with the actuator disconnected unless the latch is secured.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the door trim panel

• Use a trim panel tool to pry off the trim cover behind the interior door handle and remove the hidden screw with a Phillips screwdriver.

Step 2: Remove the moisture barrier

• Carefully peel back the vapor barrier from the door shell.
• Use a small flat-blade screwdriver only if needed to lift the adhesive edge.

Step 3: Disconnect the lock and handle linkages

• Use needle-nose pliers to release the rod retainers from the latch and handle levers.
• Disconnect any electrical connectors attached to the latch/actuator assembly.

• Use a Torx T30 screwdriver to remove the latch mounting screws at the door edge.

• Tighten the latch screws to 7.0 Nm (62 in-lbs).
• Reconnect all electrical connectors until they click.
• Reattach the lock and handle rods using needle-nose pliers.

Step 6: Test the mechanism before reassembly

• Reconnect the battery temporarily and test the power lock, inside handle, and outside handle.
• Use the key fob and door switch to confirm the actuator locks and unlocks smoothly.
• If the latch does not move correctly, recheck rod placement and connector seating.
• Disconnect the battery again before finishing assembly.

Step 7: Reinstall the moisture barrier and door panel

• Press the vapor barrier back into place using the original adhesive or door vapor barrier adhesive or butyl sealant.
