it is not always advisable to replace a high amp sa FUSES, mag up ka lang ng 5amp delikado na. Coz if mataas yun a,mp and d kaya nun part paputukin siya yun WIRES mo ang magbabaga. it's either may ground o loose yun connection mo, or worst maliit yun wires na installed sa car mo if it's not original... it's not normal na matunaw yun fuse holder or the fuse itself.
