I’m not sure about the locks, but I had a similar issue with the power windows. My passenger window wouldn’t work at all because of a bad driver side window switch. I remember it seemed odd to me that it wouldn’t even work with the passenger side switch until I replaced the driver side switch. I guess power runs through the driver side switch to the passenger side.

Another thing you might check, is there are relays for the power locks mounted on the firewall in the area up behind the gas pedal.
