• Use care around the side airbag in the door. Do not probe yellow connectors.
• Keep the ignition off while unplugging door harness connectors.
• Work with the door fully open for easier access.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the door trim panel

• Use a trim panel removal tool to gently pop off the door pull covers and switch bezel.
• Use a 7mm socket or Torx T20 screwdriver to remove the visible panel screws.
• Starting at a lower corner, use the trim panel removal tool to release the retaining clips around the edge.
• Lift the panel upward to unhook it from the window ledge.
• Disconnect the electrical connectors for the window switch and any courtesy light.

Step 2: Remove the water shield

• Use a small flat screwdriver or pick tool to carefully peel back the vapor barrier.
• Keep the adhesive clean so it can be reused. Replace it if it tears.
• Do not tear the foam barrier if you can avoid it.

Step 3: Disconnect the latch cables and connector

• Use a pick tool to rotate the cable retaining tabs and release the interior handle cable and lock cable from the latch.
• Unplug the latch electrical connector by pressing the lock tab first.
• Make sure the cables are free and note their routing.

Step 4: Remove the lock actuator/latch assembly

• Use a 10mm socket with a short extension to remove the door latch bolts on the door edge.
• Typical Ford service tightening spec on reassembly is 9 N·m (80 in-lbs).
• Pull the latch assembly out through the access opening while guiding the rods and cables free.
• If the latch is tight, use the needle-nose pliers to help guide the cables, not to force the latch.

Step 5: Install the new latch/actuator assembly

• Position the new latch in the door and route it the same way as the old one.
• Use the 10mm socket to install the latch bolts finger-tight first.
• Reconnect the electrical connector and both cables.
• Torque the latch bolts to 9 N·m (80 in-lbs).
• Make sure each cable snaps fully into place.

Step 6: Reassemble the door

• Press the vapor barrier back into place. Replace adhesive if needed.
• Reconnect the window switch and courtesy light connectors.
• Hang the door panel on the upper window ledge, then press the clips in by hand.
• Install all screws with the 7mm socket or Torx T20 screwdriver and tighten to 2-3 N·m (18-27 in-lbs).
• Reinstall covers and trim pieces.

• If the door still won’t lock or unlock, scan for body control module codes.
