Do the rear door locks operate in lock and unlock mode using the lock switch and have you check the connections in the door jam connectors for corrosion or water intrusion? There are gray and tan wires in both door jam connectors (x700 and x800) that come from the bcm to control the locks. I can send a schematic if needed.
they don't work at all, the drivers side rear moves a little but that's it. I tested wires they are receiving signal from bcm
It would appear you have multiple lock actuator failures. It's not terribly uncommon.
I've never had a bcm failure cause this and I've replaced numerous lock assemblies on these.
