Relay/fuse box (Box B)
The fuses in the relay/fuse box generally protect the electrical components in the engine compartment.
The fuses are located under the cover in the relay/fuse box. Undo the four clamps and pull out the fuse
you want to check. Look at the fuse from the side to see if there is a break in the curved wire. Should you
need to replace a fuse, you will find spare fuses in the central fuse box in the passenger compartment.
Replace the blown fuse with a new one of the same amperage and color. Never use a fuse with a higher
amperage! There are a pair of pliers, to help when replacing fuses, in the central fuse box in the passenger
