All five locks not working. 1993 RHD 3.1 Bighorn. power (12v) on both sides of the fuse. only 5 volts at the actuator in the door. RH kick panel removed door disconnected. all wires have continuity from disconnect to actuator. plug also shows 5 v. ....thoughts

So now I have both front door cards removed, (its a RHD) so expected 12v to be found in the RH door, only 5v hmmm, Lh door card removed last night , it has a different style of pull actuator and unlock sensor , on th right both are built into the same unit. but no voltage on the Left side either. Tempted to just put it all back together and live with the snag......thoughts

Its become clear that I do not have the correct wire diagram, after the fuse, the wire goes from the driver side (right) and goes up and acrossthe underside of the dash to the left. Does any one have a wire diagram for a RHD 1993 Bighorn power lock....my diagram is for a 98,

Try planet isuzu, remember finding something there a while ago. I have a 94, not sure they are the same. In mine the doors are driven from a box behind the passenger side kick panel. It is dark grey, The two upper right connectors are open and close (sorry cant remember which is which) which should be sitting at 12v and are negative switch. The rest of the connectors drive the door actualtors.
