By they sure add problems when they add complexity, huh? The fastest thing to do if you suspect a sticking relay is to just swap a few around, then see if something else is affected. The computer is a good suspect too but it's not unheard of for a relay to stick if the contacts arc enough to weld themselves together.

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.

Thanks guys. This was helpful. I'll try to find a layout of the SJB to identify the location of the "A" relays and swap them around.

Sorry I could not find any reference to the relays on the SJB. It looks like the relay are incorporated into the it therefore you would not be able to swap them.

If you are able to get a scan, check for Body Control Module trouble codes. It can help in diagnosing the problem.
