I had a problem with the wires in my rear driver side power window and lock and found that the wires were broken where the door opens and closes. I fixed those, but then the automatic door lock stopped working. All my power windows work,
When I use the remote entry key or the door lock switch on both the driver and the passenger side, I hear the relay clicks, but none of the door actuators works (doors don't lock/unlock). It has to be a fuse or a relay that controls the door locks but not the power window, because the latter ones work just fine.
If you can here relays when unlocking/locking check for power at door lock actuators inside doors, if you have power on lock/unlock and good earth from connector actuators are faulty.
if no power on test light when operating check output from central door lock module while operating, none coming out of module then it might need replacing.
check 30Amp power fuse for main relay under bonnet (which goes to pin 8 white/blue on module)and 10Amp gauge fuse in cab(pin 1 blue/red on module),pin 15 is also power when relay is on(red/blue) with test light, and module/ actuators.
check outputs from module pin 3 & 4
blue/red
blue/black
that go to door locks
