I did the door lock relay mod on my 87(88)FJ62 but still have 7.5-8 volts at the rr door actuator harness. The drivers door reads about the same too. The door will lock 98% of the time but doesn't want to unlock. If I pull on the knob just slightly it works. I have lubed everything up but that hasn't helped. The rr is the only door that is giving me fits, all the others work great. I even swaped out a spare actuator I have with the same results. Is it a bad wire going to that door? Why does the drivers door work fine with the same voltage? Where are the factory door lock relays? How about the harness going to the door, does it have a plug in it? I'm getting frustrated with this thing!
