Checking and Replacing Fuses

Fuses and circuit breakers protect your vehicle’s electrical system from overloading. If electrical parts in your vehicle are not working, the system may have been overloaded and blown a fuse or tripped a circuit breaker. Before you replace or repair any electrical parts, check the appropriate fuses or circuit breakers.

To check a fuse, look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse.


  • Before replacing fuses check that the key has been removed from the ignition and that all the services are switched off and/or disengaged.
  • Always disconnect the battery before servicing high current fuses.
  • Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can cause severe wire damage and could start a fire.
  • Never replace a broken fuse with anything other than a new fuse. Use always an intact fuse of the same color.
  • If a fuse blows again contact a qualified service center.
