⚠️ Safety & Precautions

• Disconnect the negative battery cable before working inside the door. This helps prevent accidental short circuits.
• Be careful around the side curtain airbag area in the door frame. Do not probe yellow airbag connectors.
• Use trim tools only. A flat screwdriver can damage the panel and clips.
• The door glass and regulator are inside the same area. Keep fingers clear of moving parts.
• Support the door panel as you remove it so it does not fall and break clips.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the interior trim pieces

• Use a flat trim tool to pry off the small trim cover behind the interior door handle.
• Use a Phillips screwdriver to remove the screw under that cover.
• Use a trim panel removal tool to pop off the switch bezel or small trim pieces around the armrest, if equipped.
• Work slowly to avoid broken clips.

Step 2: Remove the door panel

• Use a trim panel removal tool to release the lower and side door panel clips.
• Lift the panel upward to unhook it from the window ledge.
• Disconnect the electrical connector for the power window switch, if equipped.
• Set the panel aside on a clean surface.

Step 3: Remove the vapor barrier

• Use a flat trim tool to slowly peel back the vapor barrier.
• Do not tear it. Keep the adhesive clean so it can be reused or resealed.
• Do not rip the foam barrier.

Step 4: Disconnect the latch and actuator

• Use a 10mm socket and ratchet to remove the inner door handle rod retainers, if fitted.
• Use needle-nose pliers to release any cable clips or rod clips carefully.
• Unplug the actuator electrical connector.
• Remove any plastic access covers in the door shell.

Step 5: Remove the latch assembly

• Use a Torx T30 screwdriver to remove the latch mounting screws on the door edge.
• Slide the latch/actuator assembly out of the door.
• Keep track of how the rods and cables sit before removal.
• Tighten later to 7.5 N·m (66 in-lbs) on reassembly.

Step 6: Install the new actuator assembly

• Position the new latch/actuator assembly in the same orientation as the original.
• Reconnect the rods, cables, and electrical connector.
• Install the Torx mounting screws by hand first.
• Use a Torx T30 screwdriver to tighten them to 7.5 N·m (66 in-lbs).

Step 7: Test before reassembly

• Reconnect the battery temporarily.
• Use the key fob and interior switch to lock and unlock the door.
• Open and close the door to make sure the latch works smoothly.
• If it does not work, recheck the connector and rod clips before reinstalling the panel.

Step 8: Reinstall the door panel

• Remove the battery connection again before finishing the trim work.
• Press the vapor barrier back into place using the original adhesive or butyl tape.
• Reconnect the switch connector and align the panel on the top window ledge.
• Use your hands first, then a trim panel removal tool to seat all clips.
• Reinstall the screw and trim covers.

✅ After Repair

• Test lock, unlock, inside handle operation, and outside handle operation.
• Check that the door closes firmly and the latch does not bind.
