Can the electric door lock actuators be disconnected locally and locking be
performed manually?
Would someone inform me of the attributes of failing actuators?
Assumption: Working correctly, any one manually operated, un/locks the
others electrically.

Observations:

My DS actuator seems to have recently become a slave to the PS actuator.
To unlock the hatch I've always had to lock the cockpit doors first.  It's
as if the hatch will lock but not unlock electrically.
The DS or PS worked last year as I assume (above) but now when I pull the
DS knob up the PS immediately forces it to lock again.
The slider will lock electrically only if the cockpit doors are locked
before I shut it.  I think it also unlocks in response to the cockpit
actuators.

I'd rather not R&R all of them but simply by deduction and your experience
R&R the one/s that are failing.  Please/thanks!
