Fuses are important to any driver. If they get worn out, you might experience a turn signal failure or notice that the horn is not blowing properly. Your car may also refuse to start. It is important to note that fuses blow out before further electrical damage on the more expensive parts. As much as replacing the fuse is easy, the real task is identifying which fuse is spoilt.
