First ensure the dimmer switch for the instrument panel / dome lamps is turned off. Is the "Door Ajar" lamp illuminated in your vehicle when driving as well? If so, try lubricating each door latch as well as rear hatch with WD-40. There is a door ajar switch in each latch, if it sticks it will not allow interior lamps to turn off.
