when you move the car and it blows fuses you must have a wire touching /grounding out. go to that circuit and see if you can find any bare wires . If it's the courtesy circuit check your underhood light, trunk lightor lights under the dash. It could be something in the cigarette lighter as well...

Does this happen with key on-engine off ? If you don't have a wire pinched when you shift it, key on- e/off, you could have a problem with the neutral safety switch. I've seen them actually come apart and short to ground when shifted.
