Done an 08 but should be the same. Remove the black fiber cover on the inside of the trunk lid (push pins). The tag light fixtures do not need to be removed but AFTER the center switch is removed you can for cleaning. They have a notch that fits the sheetmetal to the outside and a spring clip to the middle of the car. Push on the side closer to the middle of the car from the inside of the trunk. But back to your question, the center switch has 4 spring clips on the long sides of the fixture - 2 on each long side. After unplugging the wires to the switch, push from the inside of the trunk. It is tight with the corrosion from 13 or 14 years but will just pop out to the outside. Hope this helps. Good Luck
