My driver side rear door doesn't lock (or unlock) from remote or driver door switch. Door handle, latch, and manual lock all work fine. Normally I would suspect a broken wire in the door jamb, but I think it's the actuator assembly. I'm looking for some info on, and/or a wiring diagram to troubleshoot. I've pulled it apart and it has 4 wires. Pink, black, pink w/black, and white. I would like to confirm the voltages are correct before I buy a new assembly.
