⚠️ Safety & Precautions

• ⚠️ Disconnect the negative battery cable before unplugging door electrical connectors.
• ⚠️ Keep the rear window fully raised before starting so the glass does not block access inside the door.
• ⚠️ Do not pull hard on door wiring. Release connector locks first.
• ⚠️ Do not close the rear door until the latch is tested and confirmed open.
• ⚠️ Wear gloves because the inside of the door shell has sharp metal edges.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the Rear Door Handle Trim Cover

• Use a plastic pry tool set to gently lift the trim cover inside the rear door pull handle.
• Work around the edges slowly so the plastic tabs do not break.
• Use plastic tools only.

Step 2: Remove the Rear Door Panel Screws

• Use a 7mm socket with a ratchet 1/4-inch drive and ratchet extension 6-inch to remove the screws hidden behind the handle trim cover.
• Use a Torx T20 screwdriver or Torx T25 screwdriver to remove any small screws at the lower edge or inner handle area, if present.
• Put the screws in a cup or magnetic tray so they do not get lost.

Step 3: Release the Rear Door Trim Panel Clips

• Use a trim clip removal tool at the lower rear corner of the door panel.
• Pop the clips loose one at a time along the bottom and sides.
• A trim clip removal tool is a fork-shaped pry tool that pulls plastic clips out evenly.
• Once the clips are free, lift the panel straight upward to unhook it from the window ledge.

Step 4: Disconnect Rear Door Panel Wiring and Cable

• Hold the rear door panel close to the door so the wires are not stretched.
• Use a pick tool 90-degree to release connector lock tabs if needed, then unplug the window switch and courtesy light connectors.
• Use needle-nose pliers to rotate the inside handle cable retainer out of its bracket.
• Unhook the cable end from the interior handle lever.
• Set the panel on a clean towel with the finished side facing up.

Step 5: Peel Back the Rear Door Water Shield

• Use a plastic pry tool set to carefully separate the water shield from the sticky black butyl seal.
• Butyl sealing tape is a soft adhesive strip that keeps water from entering the cabin.
• Peel back only the rear section near the latch area.
• Do not tear the shield. It must reseal later.

Step 6: Photograph the Latch Cables and Rods

• Use your phone to take a clear photo of the latch area before disconnecting anything.
• This helps you reinstall each cable and rod in the correct place.
• Use a work light if visibility is poor.
• Photos prevent mix-ups.

Step 7: Disconnect the Rear Latch Electrical Connector

• Use a pick tool 90-degree to release the lock tab on the latch electrical connector.
• Pull the connector straight out by the plastic body.
• Do not pull on the wires.

Step 8: Disconnect the Latch Rods and Cables

• Use a pick tool 90-degree to flip open each plastic retaining clip on the latch rods or cables.
• Use needle-nose pliers to lift the rod or cable end out of the latch lever.
• Keep each rod/cable in the same routing path it had originally.
• Make sure the child safety lock cable or lever is not forced or bent.

Step 9: Remove the Rear Door Latch Screws

• Open the rear door and look at the rear edge where the latch grabs the body striker.
• Use a Torx T30 socket or Torx T40 socket with a ratchet 1/4-inch drive to remove the 3 latch mounting screws.
• Hold the latch inside the door with your other hand while removing the last screw.
• Keep the Torx bit fully seated so the screw heads do not strip.

Step 10: Remove the Rear Lock Actuator/Latch Assembly

• Guide the latch/actuator assembly out through the rear door access opening by hand.
• Use a plastic pry tool set to gently move wiring or the water shield aside if needed.
• Compare the old and new assemblies before installation. Connector shape, latch shape, and lever positions should match.

Step 11: Install the New Rear Lock Actuator/Latch Assembly

• Place the new latch/actuator assembly inside the door by hand.
• Line it up with the 3 mounting holes on the rear door edge.
• Start all 3 latch screws by hand first to avoid cross-threading.
• Use a Torx T30 socket or Torx T40 socket with a torque wrench inch-pound to Torque to 10 Nm (89 in-lbs).

Step 12: Reconnect Rods, Cables, and Electrical Connector

• Use needle-nose pliers to place each cable or rod end into the correct latch lever.
• Use a pick tool 90-degree to snap each plastic retaining clip fully closed.
• Push the electrical connector into the latch by hand until it clicks.
• Confirm the child safety lock lever moves freely if equipped.

Step 13: Test the Rear Latch Before Closing the Door

• Use a flat-blade screwdriver 1/4-inch to push the latch claw closed, simulating the body striker.
• Reconnect the negative battery cable temporarily using a 10mm wrench.
• Press the lock and unlock switch to confirm actuator movement.
• Pull the inside handle cable by hand and confirm the latch releases.
• Use the flat-blade screwdriver 1/4-inch to make sure the latch is reset to the open position before closing the door.
• Test before final assembly.

Step 14: Reseal the Water Shield

• Use your fingers and a plastic pry tool set to press the water shield back into the butyl seal.
• If the butyl is no longer sticky, apply butyl sealing tape to the weak area.
• Seal the lower edge carefully so water drains out of the door instead of into the cabin.

Step 15: Reinstall the Rear Door Trim Panel

• Reconnect the inside handle cable by hand and lock its retainer into the bracket.
• Reconnect the window switch and courtesy light connectors by hand until they click.
• Hook the top of the panel over the window ledge.
• Press around the panel edges with your palm to seat the retaining clips.
• Use a 7mm socket with a ratchet 1/4-inch drive to reinstall the panel screws.
• Use a Torx T20 screwdriver or Torx T25 screwdriver to reinstall any small trim screws removed earlier.

Step 16: Reinstall Trim Covers and Finalize

• Snap the rear door handle trim cover back into place by hand.
• Use a 10mm wrench to reconnect and tighten the negative battery cable.
• Do not overtighten the battery terminal clamp.

✅ After Repair

• Check child safety lock operation if equipped.
• Close the rear door gently the first time and confirm it latches and opens normally.
• Check that the window switch, speaker, courtesy light, and lock switch work correctly.
• If one-touch window operation acts up after battery disconnect, run the window fully down and hold 2 seconds, then fully up and hold 2 seconds.
