Honda Fit door lock actuator problem - Part I

In this video I take the interior panel off the drivers door on my 2009 Honda Fit. The door locks cycle over-and-over whenever you lock the door. What I'm hearing is that one of the doors can't tell it's locked so it tries to 'fix it'. This happens when the door auto-lock on takeoff or when you lock the doors with the key fob thingy and walk away. I experimented with removing fuses and found that with one pulled everything worked except for the driver's door itself (so I had to lock it manually with the key). That told me I had to replace the drivers door locking actuator unit. I ordered it online and while waiting for it, the lock cycling noise returned :-( So anyway, back to the drawing board on that one but at least I can 'stiffen-up' the armrest on that door because the plastic cracked.
