The power to the license plate lamps is provided by the body control module (BCM).
Have you checked the bulbs themselves? If you look at the first two pics below, they are the directions for replacing the bulbs.
If you have checked the bulbs, we need to check if there is power to them and if they are getting a ground.
If you look at pic 3, it provides the wiring schematic for these lights. Note the power is from the body control module via a light green wire with a yellow tracer. With the lights on, check to see if there is power to that wire at the light socket. All you need is a test lamp or a multimeter.
If there is power, then we need to check for continuity to ground via the back wire at the connector.
