This article applies to the Ford F-150.
Power door lock actuators are an important component in your power lock system, and though they are a pretty simple device in operation, failure can lead to a non-working system. Actuators feature a small electric motor that turns a series of gears which turn the actuator rod, which in turn locks or unlocks your doors. Whether the motor fails or the gears break, eventually actuators will need to be replaced. Keep reading and we’ll walk you through the process.

Remove the two bolts on the bottom of the door panel, then pry off the trim piece in the front middle section (over the door speaker). Remove the bolts holding the speaker in place, pull it out, and disconnect the harness on the back. Pry off the door switch assembly and disconnect the harness on the back. Remove the bolt behind where you pulled the door switch assembly out from. Pry off the trim piece surrounding the door handle and remove the bolts behind it. Pull the handle out and lift up on the door panel to release it, then disconnect the harness from the back and remove the door panel.

Pull the entire lock mechanism up and guide it out of the door.
Unplug the harness from the mechanism and use a screwdriver to push out the clips holding the actuator to the mechanism, then pull it off.
Step 3 – Install new door lock actuator
Point the lock rod up and push the new actuator in place. Reconnect the harness and feed the assembly back in the door. Push the bottom clip back in the door. Reinstall the T27 screws near the latch to hold it in place. Clip in the lock rod and reinstall the cable. Re-clip the harness and reinstall the rest of the screws near the latch, then tighten. Reinstall the door handle as well as replace the bolts behind it and in the side of the door, then replace the rubber plugs. Reinstall the plastic water shield over the inside of the door and reinstall the speaker as well as door panel.
