🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove trim pieces and hardware

• Use the flat plastic pick tool and trim panel removal tool to remove the small trim covers around the interior door handle and armrest.
• Use the 7mm socket and Torx T20 screwdriver to remove the visible panel screws.
• Set the screws aside in order so they go back in the same places.

Step 2: Remove the inner door panel

• Use the trim panel removal tool to release the door panel clips around the edge.
• Lift the panel straight up to unhook it from the window ledge.
• Disconnect the electrical connectors for the window switch, speaker, and any courtesy light.
• Pull clips straight out to avoid breaking them.

Step 3: Peel back the vapor barrier

• Use the flat plastic pick tool to carefully lift the vapor barrier from the door.
• Peel it back slowly and keep the adhesive clean so you can reuse it.
• If the seal tears, plan to reseal it with vapor barrier adhesive sealant.

Step 4: Disconnect the latch cables and wiring

• Use your fingers and needle-nose pliers to release the interior handle cable and any connector locks from the latch area.
• Unplug the actuator wiring connector.

Step 5: Remove the latch and lock actuator assembly

• Use the 10mm socket and short extension to remove the latch mounting bolts on the door edge.
• Pull the latch/actuator assembly out through the access opening in the door.
• If needed, use the Torx T30 screwdriver on any bracket or guide fasteners attached to the latch.
• Torque to 8 Nm (71 in-lbs) when reinstalling the latch bolts.

Step 6: Install the new actuator assembly

• Compare the new part to the old one before installation.
• Feed the new latch/actuator assembly into the door the same way the old one came out.
• Reconnect the wiring connector and any cables.
• Install the latch bolts with the 10mm socket and tighten to 8 Nm (71 in-lbs).

Step 7: Reassemble the door

• Press the vapor barrier back into place and reseal any torn areas.
• Reconnect the door panel electrical connectors.
• Hook the top of the door panel onto the window ledge, then press the clips back in.
• Install the screws with the 7mm socket and Torx T20 screwdriver.
• Torque to 2 Nm (18 in-lbs) for small trim screws.

Step 8: Restore power and test
