Hello. I just purchased a 2005 F150 (4.6L / 4 door). The lot I purchased it from had picked it up at auction. Tell-Tell signs indicate it was a repo. (Only one key, no fobs, locking fuel filler door jimmied and spring removed, scratches on upper corner of driver's side door and rubber bent back.

The power locks switch on arm rest works on all doors except driver's. The drivers door does lock and unlock manually. I am wanting a good hypothesis before I begin tearing into the door panel.

If the latching mechanism was damaged, it wouldn't lock manually, right? If the electronics were damaged the other doors wouldn't work right? So, my hypothesis is the actuator on driver's door. Does anyone have another idea, so I can start searching for/locating possible replacement parts?

Thank you in advance for any and all help.

 

Actuator or a broken wire would be my guess
