Open the trunk take the plastic srew behind taillight out and move the pice of trunk rug out of the way. You should be able to see the back of the bulbs just turn them to left and they will come...
check your fuses . if it continues to blow the fuses when the brake is mashed then look under the dash @ drivers side and see if there are ne wires touchin on the steering column or ne metal.
