Power door locks fail quite often on late-model Ford vehicles. They’re controlled by a computer, but most often it’s the actuator itself that’s failed—not the computer. So if you press the lock/unlock button and hear clicking or see that the lock is moving, but not enough to open the door, the actuator is fried. A new actuator costs about $50, and you can save about $75 in shop labor if you do the job yourself. Along with ordinary screwdrivers and sockets, you’ll need a few inexpensive special tools: a door handle remover for crank windows (about $7 from any auto parts store) and a flat-blade offset screwdriver.
Buy a new actuator online (silverstatefordparts.com) or from your local Ford dealer. Then remove the interior door trim panel (consult a shop manual for screw and snap locations). It’s hard to see in these photos, but the trick involves using a flat-blade screwdriver to pry the old actuator off the latch while you depress the actuator locking tab with the flat blade of the offset screwdriver. You’ll be working blind behind the door structure, so examine the new part to get a feel for how the locking tab works.
