If the left door is working correctly, I believe the passenger unlock relay is the culprit.
When locks are in a state of idle, both wires would have battery voltage. When unlock signal is received, the relay wuld be triggerred to ground the Light Blue wire.
Remove the relay and test the Light Blue wire for continuity to ground. If continuity exist, the control unit is faulty.
These are "A" relays and you should not be swapping with the main door lock relay. Only sway with the driver door unlock relay and test if problem is also transferred.
