⚠️ Safety & Precautions

• Assumption: this is for one front door actuator; the procedure is similar for driver or passenger side.
• Disconnect the negative battery cable before unplugging the door harness. This helps prevent airbag or module faults.
• Be careful around the side curtain airbag area at the upper door frame and A-pillar.
• Use trim tools only. Metal tools can crack the door panel and scratch the paint.
• Support the glass if the door panel needs to be moved far from the door.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the door trim pieces

• Use a flat plastic pry tool and trim panel removal tool to pop off the small trim covers on the armrest and door pull.
• Use a 7mm socket to remove the exposed screws behind the trim covers.
• Use a pick tool to remove any screw caps or small bezels without breaking them.

Step 2: Remove the door panel

• Use a trim panel removal tool to release the clips around the lower and side edges of the door panel.
• Lift the panel straight up to unhook it from the top window ledge.
• Disconnect the electrical connectors for the window switch, speaker, and puddle light if equipped.
• Unplug the door handle cable by rotating the retainer and lifting the cable end out.

Step 3: Peel back the moisture barrier

• Use a flat plastic pry tool to carefully loosen the door vapor barrier.
• Peel it back just enough to access the latch area.
• Do not tear the barrier.

Step 4: Remove the door handle and latch hardware

• Use a 10mm socket and ratchet to remove the door handle fasteners if required for access.
• Use a Torx T30 screwdriver to remove the latch-to-door screws at the rear edge of the door.
• Use a Torx T20 screwdriver to remove any actuator mounting screws or bracket screws attached to the latch assembly.
• Torque on reassembly: tighten small latch and actuator fasteners to 2.5-4 Nm (22-35 in-lbs).

Step 5: Disconnect the actuator and release cables

• Use a pick tool to release the cable retainers from the latch assembly.
• Disconnect the electrical connector from the actuator.
• Pull the handle rods or cables out of the latch in the same order they were removed.
• Take a photo before disconnecting anything.

Step 6: Remove the actuator/latch assembly

• Slide the latch and actuator assembly out through the service opening in the door.
• If it will not clear, rotate it slowly and guide the rods and wiring through the opening.
• Use a needle-nose pliers only if a clip is stubborn and cannot be released by hand.

Step 7: Install the new actuator

• Transfer any rods, clips, or brackets to the new actuator if your replacement is not a complete latch assembly.
• Install the new actuator/latch assembly into the door in the same orientation as the old one.
• Reconnect the electrical connector and all rods or cables.
• Use a Torx T20 screwdriver and Torx T30 screwdriver to reinstall the fasteners.
• Torque on reassembly: tighten fasteners to 2.5-4 Nm (22-35 in-lbs).

Step 8: Test the latch before reassembly

• Reconnect the negative battery cable temporarily.
• Use the key fob and interior switch to lock and unlock the door several times.
• Check that the inside handle, outside handle, and child lock function correctly if equipped.
• Disconnect the battery again before finishing the door panel install.

Step 9: Reinstall the moisture barrier and door panel

• Press the vapor barrier back into place using the original adhesive or new butyl barrier tape.
• Reconnect the door panel electrical connectors and handle cable.
• Hang the top edge of the panel on the window ledge, then press the clips back into place.
• Use a 7mm socket to reinstall the screws and tighten them snugly.
• Torque on reassembly: snug trim screws to 2.0-3 Nm (18-27 in-lbs).
