The fuse keeps blowing because you have a short to ground in the circuit that the fuse is protecting. This happens because of one of the laws of Ohm's law, the laws that govern electricity. This law states that if one of the three properties of electricity is constant[Voltage-Voltage is always constant in an automotive application, battery voltage] and one of the other two go down[Resistance-Resistance goes to zero when a short to ground happens as there is a direct path back to the battery's negative terminal] then the last property must go up proportionally[Amperage-Amperage/Current goes up to battery amperage]. The amperage surpasses the amperage rating of the fuse and "pop", the fuse blows protecting the component[s] in the circuit, just as it was designed to do. So, you need to find the short to ground, fix it, then replace the fuse. In the diagrams down below I have included the Power-train Management wiring diagrams and call outs and a guide explaining how to find sort to grounds in an automotive electrical circuit. You will need to use a Digital Multi Meter[DMM] to go through these guides, so here is a link below explaining how to use one below, if needed:
