Hi PRincess Rex has posted a picture of the fuse box in this thread. http://forums.copenworld.com/showthread.php?t=356 it's located to the right of the steering wheel under the little cubby hole. Where your right knee goes. The fuse you need is the bottom right. It's a 15 amp fuse. See section 13-12 of your owners manual. If it's working it would be clearing your rear window if mist & ice in this weather.
