Any time you have a fuse that blows that means that there is a short to ground in the circuit(s) that the fuse is protecting. This happens because of Ohm's Law, the laws that govern electricity in your automobile. Ohm's law states that if one of the three properties of electricity is constant, which one always is in a vehicle(Voltage-Battery Voltage) and one of the other two goes down(Resistance-Resistance drops to zero with a direct ground path back to the battery) then the last property(Amperage/Current-Amps will go to the battery amperage rating) must go up proportionally. The amps will quickly exceed the Amp rating of the fuse and POP, the fuse blows just like it was designed to and protects the circuit for being welded together or an electrical fire. In the diagrams down below I have included the wiring diagram for the AC circuit in your vehicle as well as a guide for how to find a short to ground in an automotive electrical circuit. Please go through these guides, check your vehicle's AC circuit, find and repair the short to ground, and report back with how everything turns out, please.
