Checking and Replacing Fuses

Fuses protect the car’s electrical systems from short circuits. To check a fuse, look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a new one of the identical size and rating.

Fuses of the same amperage can be temporarily borrowed from another fuse location if a fuse goes out. Replace the fuse as soon as possible.

Note

  • Disconnect the battery negative (-) cables from the right and left batteries before removing the fuse box cover.
  • When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload.
  • If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected.

Engine Compartment Fuse Box Diagram

Your vehicle is equipped with a fuse and relay center located in the engine compartment near the battery. Located on the underside of the cover is a label that identifies each component.
