Checking and Replacing Fuses

The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links in the wiring itself. This greatly reduces the chance of fires caused by electrical problems.

Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating.

If you ever have a problem on the road and don’t have a spare fuse, you can borrow one that has the same amperage. Just pick some feature of your vehicle that you can get along without – like the radio or cigarette lighter – and use its fuse if it is the correct amperage. Replace it as soon as you can.


  • You can remove fuses with a fuse extractor. The fuse extractor is mounted to the fuse block access door. To remove fuses, if you don’t have a fuse extractor, hold the end of the fuse between your thumb and index finger and pull straight out.
  • You may have spare fuses attached to the inside of the fuse block access door. These can be used to replace a bad fuse. However, make sure that it is the correct amperage.
  • 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.
  • Do not repair fuses and never replace a blown fuse with one that has a higher amp rating. This can cause damage to the electrical system and 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 authorized services.
