🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the inner door trim panel

• Use a trim removal tool to carefully pry up the window/lock switch bezel (if equipped) and unplug the connector(s).
• Remove visible screws using a Phillips #2 screwdriver and/or Torx T20 screwdriver (commonly in the pull handle and around the panel).
• Use panel clip pliers (specialty) or a trim removal tool to pop the panel clips free around the edges.
• Lift the panel upward to unhook it from the top window channel, then set it aside.

Step 2: Remove the water shield (plastic moisture barrier)

• Gently peel the water shield back using your hands and a pick tool as needed.
• If the butyl is stringy, go slow and keep it clean so it can be reused; if it won’t reseal, you’ll replace it with butyl sealant.

Step 3: Disconnect the inside handle and lock linkages

• Locate the latch/actuator area at the rear of the door (near the door edge).
• Use needle-nose pliers and a pick tool to open the plastic retaining clips (they “flip” open), then lift the metal rods out of the clips.
• Driver door note: If your door has a key cylinder, you’ll have an additional rod/cable to disconnect at the latch.

Step 4: Unplug the latch/actuator electrical connector

• Press the connector lock tab and unplug the latch connector by hand; if stuck, use a pick tool carefully on the tab.
• Don’t pull on the wires.

Step 5: Remove the latch/actuator from the door

• Open the door and locate the latch fasteners on the door’s trailing edge.
• Use a Torx T30 driver to remove the latch mounting screws.
• Carefully work the latch/actuator assembly out through the access opening in the door.
• If the assembly hangs up, re-check for any rod/cable still clipped in place and release it using needle-nose pliers.
• When installing the new latch, start all Torx screws by hand, then tighten evenly: Torque to 71 in-lbs (8 Nm).

Step 6: Reconnect rods/cables and verify clip engagement

• Reinstall each rod into its lever, then rotate/press the retaining clip fully closed by hand (use needle-nose pliers only if needed).
• A half-closed clip will cause lock/handle failure.

Step 7: Reconnect wiring and function-check before reassembly

• Plug the latch connector back in until it clicks.
• Reconnect the battery negative terminal using a 10mm socket: Torque to 50 in-lbs (5.6 Nm).
• With the door open, test:
  • Power lock/unlock operation
  • Inside handle opens the latch
  • Outside handle opens the latch
  • Key cylinder operation (driver door, if equipped)
• Disconnect the negative battery cable again using a 10mm socket before putting the panel back on.

Step 8: Reinstall the water shield and door panel

• Press the water shield back into the butyl; add butyl sealant as needed to fully seal the perimeter.
• Hang the door panel on the top window channel, then press clips in around the edges by hand.
• Reinstall screws with a Phillips #2 screwdriver and/or Torx T20 screwdriver until snug (do not over-tighten into plastic).
• Reconnect the switch connectors and snap the bezel back in using a trim removal tool.

Step 9: Final battery reconnect

• Reconnect the negative battery cable using a 10mm socket: Torque to 50 in-lbs (5.6 Nm).

✅ After Repair

• Test lock/unlock from the switch and (if equipped) key fob.
• Confirm the door opens from inside and outside every time.
• Check that the water shield is fully sealed to prevent water leaks.
• If the power locks act backward or don’t move fully, recheck rod routing and that each clip is fully closed.
