Door lock won't work. Please help!
Just got a 2010 f150 crewcab. The driver side rear door lock does not work. I replaced the door lock actuator and the door wiring harness. Still won't work. When I hit the unlock button the **** moves very slightly but nothing else. I'm stuck. Please help!

The contacts in the switch may be oxidized & thus making only partial contact.
Pull the drivers door switch bezel & then disconnect the wire harness.
Take the switch assembly apart using a knife blade to release the retention clips. Pull it apart & clean the silver contacts with an emery board or a ignition-points file or crocus cloth/ fine-sandpaper. When shiny, re-assemble and the window should work up/down.
Or swap the passenger side switch and drivers side switch & reconnect harness. Check for proper function. If it now works you got a bad switch assembly.
No out-of-pocket cost other than your time!
