Well, I'm going to guess that you are working on the 95 truck you have listed in your signature, since you used the word "truck". It's a little tough since I don't have a schematic on that. I assume these are manual locks where you are hitting a switch to open or lock them. One of the leads into the driver's side switch has to have 12 volts to ground all the time. Might start there. Doesn't sound like a lock actuator problem because both the drivers and passengers either work or don't work.
Is there anyone out there that can help me????????
Well here's my problem, for whatever reasons my automatic door locks seem to stop working while I'm driving and don't open with I turn the truck off. I noticed that it started when I took off the door panel to replace the inside door latch mechanism because the old door handle had broke. After I installed the new one and put everything back together the locks started not to open. They'll open like they're suppose to, but then they'll stop. I've checked my fuses and they seem fine. I've somewhat narrowed it down to it possbily being my driver's seat. Seems like when I sit down they stop working. That's the only thing I can think of now 
...I was even thinking maybe it could be some wires in the engine compartment that were suffering from all the heat. Also, if they are working while I'm in the truck and driving, I'll notice the radio's lights dim and the music sound like it doesn't have any power, then it'll start working again, BUT the locks don't I did notice when I pulled the cover for the fuses on the side of the dash on the driver's side that one of those little tin fuses, the one on top, is/gets really hot...I was thinking that maybe that was the problem or had something to do with it. I swapped it with the one below and it seemed to be working, but as soon as I got in the truck and turned it on, the locks stopped working again Well, sorry for such a long question, but this has really been biting me in the a$$......PLEASE!!!!! can anyone help??? I can really use the info and it is much appreciated. Thanks everyone!!!
