I have a 93 FWB that does not UNLOCK my driver door (with door switch/or when in park/ or with remote); it LOCKS ALL the doors with door switch, remote and when placed in Drive. I took out and tested the actuator separately and it operates under 12 volts locking and unlocking. I believe the issue may be the door lock relay however I cannot find it for the life of me! the manual diagram states it is located in the A pillar area but I've checked over and over. Any help regarding this is greatly appreciated. Thank You.
