Checking and Replacing Fuses
A fuse is an element for protecting the electrical system. A fuse will trip (i.e. it will blow) in the event of a failure or improper interventions in the electrical system.
If an electrical device is not working, check whether the respective fuse is blown. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Check those fuses first that protect the failed component, but check all the fuses before deciding that a blown fuse is not the cause. Replace any blown fuses with another with the same amperage (same color) and check the component’s operation.
Notice
- Before changing a fuse, check the ignition key has been removed and that all the other electric devices have been turned off/disabled.
- Never replace a broken fuse with anything other than a new fuse. Always use a fuse of the same color.
- Never change a fuse with another amperage. This can cause damage to the electrical system and fire.
- If the fuse blows again, have the vehicle inspected at a qualified service center.
