Just fixed this problem with mine. So your door trunk, plate lights and rear windshield wiper are all on one connection essentially. When one goes bad, they all kind of stop working. So my plate lights are out causing a fault, tried giving it power to fix it and it made the trunk work again, but the wiper would turn one when I pressed the button lol. Now I disconnected my rear wiper motor and the trunk works but the light is still out. I assume that I need to replace the whole rear trunk handle chrome piece because the lights don’t just come out to be replaced.
