Hi,

This story sounds familiar -- although my van didn't get a name out of it.
My doorlocks  were also DPO - repaired by removing the fuse to the driver's
door.  I seem to remember one fuse going to the passenger door, and another
unmarked one in the fuse block right above it that did the driver's door.
Basically, if all the door locks do not cycle properly, the cycle reverses.
 So, if the power lock in the tailgate hatch or passenger door is
mechanically stuck, then the power locks will reverse and unlock when you
try to lock them.  I had to remove the tailgate liner and lubricate the
mechanism in the rear hatch latch to fix mine.  I also had to lubricate the
lock cylinder, because I think the DPO just left it in the unlocked
(horizontal) position all the time instead of figuring out how to use the
key back there or fixing the power locks.  Of course, if you slider door is
open, then it's status cannot be changed or read by the rest of the system.
