🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear door trim fasteners

• Use the Torx T20 screwdriver to remove the screws in the pull handle and lower door trim area.
• Use the small flat-blade screwdriver to carefully pry out any screw covers first.
• Remove the visible fasteners and set them aside in order.

Step 2: Pop off the door panel

• Use the trim removal tool set to release the door panel clips around the edges.
• Work slowly around the panel until all clips release.
• Lift the panel upward to unhook it from the window ledge.
• Start at a lower corner for easier clip release.

Step 3: Disconnect the wiring

• Use the small flat-blade screwdriver if needed to release the connector locks.
• Disconnect the door handle cable and any electrical connectors for the speaker or switch panel.
• Set the door panel aside on a soft surface.

Step 4: Peel back the vapor barrier

• Use your hands and the small flat-blade screwdriver to carefully lift the vapor barrier.
• Do not tear it. You will reuse it if it is still sealing well.
• If the adhesive is weak, plan to reseal it with vapor barrier adhesive or butyl tape.

Step 5: Remove the latch/actuator assembly

• Use the Torx T30 screwdriver to remove the door latch retaining bolts on the door edge.
• Use the 10mm socket with the ratchet and extension bar if your door uses 10mm fasteners at the latch bracket.
• Unclip the actuator rod or cable linkage carefully with the needle-nose pliers.
• Remove the latch/actuator assembly through the door access opening.
• Torque on installation: tighten the latch fasteners to 8 Nm (71 in-lbs).

Step 6: Install the new actuator/latch assembly

• Position the new rear door lock actuator assembly into the door.
• Reconnect the linkage rods or cables first, then seat the assembly fully.
• Install the fasteners by hand before tightening with the Torx T30 screwdriver or 10mm socket.
• Make sure the actuator wiring is routed exactly like the original.

Step 7: Test the latch before reassembly

• Reconnect the electrical connector and battery if you disconnected it.
• Use the door lock switch and key fob to test lock and unlock operation.
• Open and close the door several times to confirm smooth latch action.
• Test now to avoid double work.

Step 8: Reinstall the vapor barrier and door panel

• Press the vapor barrier back into place and seal any gaps with vapor barrier adhesive or butyl tape.
• Reconnect all electrical connectors and the handle cable.
• Hook the door panel over the window ledge, then press the clips back in with the trim removal tool set.
• Reinstall all screws with the Torx T20 screwdriver.
• Torque on reassembly: snug the door panel screws to 2-3 Nm (18-27 in-lbs).
