⚠️ Safety & Precautions

• ⚠️ Disconnect the negative battery cable before unplugging door electrical connectors.
• ⚠️ Keep the window fully UP before starting to avoid glass movement.
• ⚠️ Use eye protection when popping trim clips (they can release suddenly).
• ⚠️ Support the door trim panel so wiring isn’t stretched.
• ⚠️ Don’t tear the water shield (vapor barrier); it prevents leaks and wind noise.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the window/lock switch panel

• Use a trim removal tool (plastic pry tool) to carefully pry up the switch panel from the armrest.
• Unplug the electrical connectors by pressing the lock tab with a small pick tool if needed. Don’t yank on the wires.

Step 2: Remove screws from the interior door trim panel

• Use a Phillips #2 screwdriver and/or Torx T20 screwdriver to remove the screws in the pull handle/armrest area and behind/near the interior handle bezel (locations vary slightly by option package).
• Place all fasteners in a magnetic parts tray.

Step 3: Pop the door trim panel clips free

• Work around the outer edge of the panel using a trim removal tool (plastic pry tool) to release the push clips.
• When all clips are loose, lift the panel straight up to unhook it from the top window channel.
• Disconnect any remaining connectors (courtesy light, etc.) using the small pick tool as needed.

Step 4: Peel back the water shield (vapor barrier)

• Use your gloved hands and a trim removal tool (plastic pry tool) to slowly peel the water shield back.
• If the butyl adhesive strings or won’t reseal well, plan to replace it with water shield butyl tape.

Step 5: Disconnect the latch/actuator electrical connector

• Locate the latch/actuator connector near the rear edge of the door (inside).
• Press the connector lock tab using a small pick tool and unplug it.
• Apply a tiny amount of dielectric grease to the seal during reassembly. Use only a thin film.

Step 6: Detach the door handle and lock rods from the latch

• Identify the metal control rods going to the latch (inside handle rod, lock rod, and outside handle rod).
• Each rod is held by a small plastic retaining clip: flip the clip open using a small pick tool, then lift the rod out of its hole.
• Use needle-nose pliers only if needed; don’t crush or kink the rod.

Step 7: Remove the latch/actuator assembly from the door

• At the door’s rear edge (the latch side), remove the latch mounting screws using a Torx T30 screwdriver.
• Support the latch inside the door and carefully maneuver it out through the access opening.
• Torque to 9 Nm (80 in-lbs) for the latch screws during installation.

Step 8: Install the new latch/actuator assembly

• Insert the new unit into position and start the screws by hand to avoid cross-threading.
• Tighten with a Torx T30 screwdriver and Torque to 9 Nm (80 in-lbs).
• Reconnect all control rods and snap each plastic retaining clip fully closed.
• Reconnect the electrical connector until it clicks.

Step 9: Re-seal the water shield and reinstall the door panel

• Press the water shield back into place; use water shield butyl tape if the original adhesive won’t seal.
• Reconnect door panel electrical connectors.
• Hang the panel on the top lip first, then press the clips in around the perimeter with firm, even pressure.
• Reinstall screws using a Phillips #2 screwdriver / Torx T20 screwdriver.
• Snap the switch panel back in and reconnect connectors.

Step 10: Reconnect battery and function-check

• Reconnect the negative battery cable using a 10mm wrench.
• Verify lock/unlock from the switch and key fob (if equipped), and confirm inside/outside handles open the door correctly.
