2002 Hyundai Sonata Power door locks not working

Just purchased the car used. The power door lock button (located on the driver's-door console) only unlocks the doors. It does not lock them. While driving, the power lock will spontaneously engage and unlock all the doors. Also, on the same console, the power window switch that controls the passenger-side window does not work (though the other three switches on the driver's-side door console work fine). Do I need to replace the entire console or is there something wrong with a fuse or something like that?
