[LX5liter]

Take a volt meter and check to see if you are getting power to the fuse to begin with. Pull out the fuse and put one probe in the lower fuse slot and ground the other probe. If you have no voltage there try the upper slot. If you still have no power trace the wire back to see where it is broken/disconnected. This will check that particular circuit. If you have other things that aren't working on different circuits it could be a ground or something else disconnected like your parents suggested.
