Checking and Replacing Fuses

Fuses and circuit breakers protect your vehicle’s electrical system from overloading. If electrical components in the vehicle are not working, the system may have been overloaded and blown a fuse or tripped a circuit breaker. Check the appropriate fuses before replacing any electrical components. A blown fuse can be identified by a break in the wire within the fuse.


  • Before replacing a fuse 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.
  • Do not repair fuses and never replace a blown fuse with one that has a higher amp rating. This can severe wire damage and could start a fire.
  • Never replace a broken fuse with anything other than a new fuse.
  • Even after a fuse is replaced, it will continue to blow if the cause of the overload is not identified and corrected. If the fuse continues to blow, have the vehicle’s electrical system checked by your dealer or a qualified service technician.
