: Where should I start next? I.E. testing current to the central : locking unit etc... How much current? Where else? What pitfalls should I look out for? All help is
: greatly appreciated. Is there a FAQ on this somewhere?

I assume the linkage connecting the door lock to the locking control unit is in place ;) The linkage keeps popping out of my rear door lock motor.
Mine failed a couple years ago. About all you can do (electrically) is check voltage at the supply terminal (red/black wire?), check continuity to ground (brown wire), and see if voltage to other terminals changes as you work the door button. I ended up replacing the control unit (found a used one, guaranteed good and all). I took the old one apart, and it's a real marvel of linkages, solenoids, cams, microswitches, etc. -- the way things were done before solid state controls were common. I've fixed a few non-repairable things, but that controller is beyond me.

Keep the shiny side up.
