Does the passenger door lock operate the lock on the passenger door?

There's a wire connecting the driver door to the other 3 and
it goes under the carpet near the center under the back of the
driver seat. The 4 wires from the 4 doors are connected with a
metal connector and that can corrode, especially if there's been
water inside the car.

It's a wire that carries the communication signal between the
driver door module and the other doors.

There are 18 pictures in this imgur collection about repairing the connector.

It may be the drivers master control, just another option to consider checking. It wasn't clear if this was only from the drivers door or each individual door and there lock switch.
