You have a short somewhere on that circuit, that fuse powers a few different systems on the vehicle. You will need to start unplugging things on the circuit until the fuse no longer blows. You can use a circuit breaker as well so you wont blow so many fuses.

I can send you a wiring diagram for this circuit if you would like.
