ok you should find screws on the inside of the hatch holding the lense assy to the body. when you remove the screws you should find the lense feels a little bit loose. the outer side of the lense should be kind of hooked in place as it should have tabs on the plastic. then you gently roll the inner(closest to the hatch) toward the outside and the assy should now be in your hands. the bulb holders usually twist slightly and then pull out. the bulb should just pull straight out. some vehicles have access panels inside the rear corner to just access the plug itself.
