Sounds like the problem may be in the door lock relay...I have a 95 Lumina with power locks and the drivers sdoor lock does noit work. I switched the rocker switch with the passenger side to check switch and its ok, ..inspected wiring and no visible signs of short there. Passenger side switch will lock and unlock drivers side, so solenoid is good, power to drivers side switch shows 11 volts..others reading 12.5..anyone know wherre the lock relays are located?
