went through a trouble shooting process on my rear driver door lock this weekend. wish I would've seen this thread first! ended up being a different issue than the motor though, the plastic arm was cracked on the backside of the the post (see red arrow). pulled the arm off, slathered with some red loctite on there as a bandaid, have ordered a replacement mechanism so I'll be ready when it fails again.
