If the door locks are working from other sources, then you can rules out a fuse as the culprit. Start at the drivers door lock switch. There should be 2 wires there, black and white. test the black wire for continuity to ground. you should have little to no resistance. If you have a good ground, test the switch by measuring resistance at the 2 terminals of the switch. when the switch is in the lock position, there should be 0ohms of resistance, and when unlocked there should be 1500ohms of resistance.
Another way of testing it, if you don't have a multimeter, is the take a jumper lead, and cross the black and white wires. The doors should lock. If you take a 1500ohm resister, and put it across the 2 wires, the doors should unlock. If the locks do not operate, try running a long extension lead directly from the negative side of the battery, and touch it to the white wire, the doors should lock, and throught the 1500ohm resister, doors should unlock. If the locks operate, then you need to repair the black wire, It should go directly to ground. If they still don't work, then Check connector 1 (72 pin grey conn, the left-most plug)at the BCM. (panel on the passeneger side of center console comes off). Pin 7 has a white wire going to is, and is the LS door lock switch signal. Do the same test at this wire with the long extension from the battery as you did at the switch. If it works, then you need to repair the white wire from the BCM to the switch. If it still doesn't work, and the passenger side does, cute the wire at pin 7, and attached it to the white wire at pin 6. Pin 6 is the passenger side door lock switch and operates exactly the same as the drivers door, and are accually crossed over inside of the bcm
Good luck
