The rear door lock and unlock uses different relays for locking and unlocking. Hey are located in left instrument panel fuse box (lower left side of dash). They can be tested but the easiest way is to swap them around and if problem changes to unable to unlock, then we know the relay is bad.
For actuators, you need to remove the door panel and disconnect the actuator wires and test with battery voltage.
I believe that part cn be sourced from parts outlets.
