looking at the door lock control schematic (034DLC.pdf) in the FSM, G-Y is unlock, and BR-W is lock. i think that should help you since you could briefly pulse +12 at one or the other (vampire tap or pin or something) and really determine if the switch is getting power, if the lock mechanism is to blame, or if one of those molexes is going wonky on you. i recall from futzing with those molexes in the armrest that both of the main ones need to be connected properly, or some functions mysteriously fail.
