2000 V8 Tundra SR5 Access Cab. Having problems with my driver side power door lock. When I push the lock/unlock button on either the driver or passenger side doors only the passenger side door lock works. I tried replacing the whole driver side power door lock assembly, but same problem. I do not have a remote for the power locks. I'm guessing this may be some sort of short, but a quick glance at the wires and connectors for the power assembly and they look fine. Any quick and easy ideas?
