the fuse should be 3 amp so when the bulb fails it blows the 3 amp fuse.if you fit a 13 amp fuse it blows the track on the pcb which is behind the buttons you press to switch light on.remove the switch panel from hood and open plastic box and look for blown track on pcb.resolder track,fit back with 3amp fuse and test.
