You might try jumping the locks at the drivers switch itself, and could try disconnecting the battery and measuring resistance from the power wire to ground. The reading should show really high resistance if any if good. I have seen several vehicle that the wires in the drivers door jam will break and depending on where they break and how many does it could be possible that the power wire broke and grounded out and after opening and closing the door could of separated the wire from ground. When I get a vehicle that the door locks and windows doesn't work thats the first place I look.
