Let me see if I can shed some light on how the 92-95 RAC Module works..
It watches the Switch Outputs.... Say you were to unlock the Doors from the passenger side, The RAC would see this and apply power to the Drivers door lock relay at that time the other 3 doors should unlock as well.. It almost sounds as if the Main door lock relay may have failed( Under the drivers seat ) Or possibly you have a bad Rac Module, But even using the switch on the Passenger door should unlock all 4 doors..
Check the Door Lock relay under the seat first before we go any further..
Ted you have any more thoughts on this one?
