Disco 1 1993 Disco 1 rear door locks not working with central locking

Hi all!
I have the above mentioned '93 D1 5 door. The central locking won't work the rear doors. The is no voltage at the actuators. The fronts and the tail door work fine.
I have re soldered all the main joints on the control unit.
Is there another plug or central earthing point I may need to check for the rear doors? The actuators do work when voltage is put direct to them.
Any help anyone?

Thank you!!
Oliver

95 may be of help

have you checked harness at door hinges? The wires can break there.

I have the same problem with the tailgate on my 1998 3-door. It worked once or twice, but usually it refuses to do anything.

Could be as simple as the motor in the actuator is seizing up, or a slight adjustment of the actuator is required so the rack operates correctly, or an intermittent voltage supply to the motor.

Take your pick
