sounds like the doors aren't talking to eachother. there is a wire that joins the door motors, so if u lock 1, it locks the other.
undo the connector on the passenger and drivers door..... the rubber bit between the door hinges and see if any off the pins have snapped off, or look corroded.
spray some WD40 in it and see if it works.
if not, it's prob a wire come off insie the door.... but most likely it's come off in that door connector.
