⚠️ Safety & Precautions

• ⚠️ Disconnect the 12V battery negative cable before unplugging door wiring to prevent shorts.
• ⚠️ Keep the key fob away from the car while working so the locks don’t cycle unexpectedly.
• ⚠️ Handle the vapor barrier carefully; it must reseal to prevent water leaks.
• ⚠️ Use plastic trim tools to avoid cracking the door panel.

• Open the rear door you’re repairing and leave it open.

• Have a clean spot ready to place the door panel so the fabric/trim doesn’t get scratched.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the rear door trim panel

• Use a plastic trim removal tool set to gently pry up the window switch panel.
• Unplug the window switch connector by pressing the tab and pulling it out by hand.
• Use a Phillips #2 screwdriver to remove the screw(s) in the pull handle area (location varies by panel style).
• Pop off the small cover behind the inside door handle using a plastic trim removal tool set, then remove the hidden screw with a Phillips #2 screwdriver.
• Use a plastic trim removal tool set to pry around the perimeter and release the panel clips.
• Lift the whole door panel straight upward to unhook it from the top lip near the window.
• Disconnect any remaining connectors (courtesy light, if equipped) by hand.

Step 2: Remove the vapor barrier (water shield)

• Carefully peel the plastic vapor barrier back using your hands and a plastic trim removal tool set.
• If the sticky butyl stretches, use a pick tool (small) to help separate it cleanly.
• Don’t tear it; water leaks start here.

Step 3: Disconnect the latch rods and electrical connector

• Locate the latch/actuator area at the rear edge of the door.
• Find the metal control rods (from the inside handle and lock). Use a pick tool (small) to flip the colored retaining clips open.
• Once the clip is flipped open, lift the rod out of the clip by hand (use needle-nose pliers if tight).
• Unplug the actuator electrical connector by pressing the locking tab (use a flat blade screwdriver (small) only if needed).
• Take a quick photo of rod routing first.

Step 4: Remove the latch/actuator assembly from the door

• At the door’s rear edge, remove the 3 latch screws using a Torx T30 bit with a 1/4" ratchet.
• Support the latch inside the door as the last screw comes out so it doesn’t drop (use a magnetic pickup tool if hardware falls).
• Work the latch/actuator assembly out through the access opening in the door.

Step 5: Install the new latch/actuator assembly

• Place the replacement latch/actuator assembly into the door the same way the old one came out.
• Start all 3 latch screws by hand, then tighten with a Torx T30 bit.
• Torque to 7.5 Nm (66 in-lbs) using an inch-pound torque wrench.
• Reconnect the actuator electrical connector until it clicks.
• Reinstall the rods into their clips, then flip each clip closed using a pick tool (small) (you should feel it “snap” shut).

Step 6: Re-seal the vapor barrier and reinstall the door panel

• Press the vapor barrier back into place firmly by hand.
• If the butyl no longer sticks well, apply butyl tape and press the barrier into it.
• Reconnect all door electrical connectors by hand.
• Hang the top of the door panel on the window ledge first, then press the clips in around the edges by hand.
• Reinstall screws with a Phillips #2 screwdriver, then reinstall the covers using a plastic trim removal tool set.
• Reinstall the window switch panel and plug it in.

Step 7: Reconnect the 12V battery

• Reconnect the 12V battery negative cable using a 10mm socket.

✅ After Repair

• Test from outside and inside: lock/unlock with the fob and the interior switch.
• Confirm the inside handle opens the door normally and the child lock (if used) still works as expected.
• Check the window switch works and the door panel is fully seated (no rattles).
• After your next car wash/rain, check the rear carpet area for moisture (verifies the vapor barrier seal).
