Left side under dash panel, check 7.5 amp "Tail" fuse, 15 amp "Tail/Panel" fuse, and 15amp "Panel" fuse. If it is only two corners, check bulbs. All 4 corner lamps and the license plate lamp are on the same circuit. If you do not have remote door locks, they are all off the "Tail" fuse, if you have remote door locks they can also be triggered thru the "Panel" fuse via the ECU. Both circuits are fed by the "Tail/Panel" fuse.
