When you press the lock button on the door do the power locks move down & then suddenly unlock again? Or it does nothing except click under the dash area?
Speaking of clicking under the dash. Get to the fuse box under the driver side dash and pull out the three door lock relays and swap each one of them so than none of them are in the same location. Let me know if this does anything or no change. Keep in mind which relay when were because if one of them is bad you'll need to know which one to replace.
Next, your friend will need to removed the left front door panel and to gain access to the two wires running to the door lock motor inside the door. The wires are colored. One is red with a white line and the other is pink with a black line. Your friend will need to find out if your getting voltage when pressing the door lock switch (lock & unlock positions) on each of these wires.
