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, a fuse may have blown. Check the appropriate fuses before replacing any electrical components.
Look carefully at the fuse – a broken wire within the fuse identifies blown fuses. If you are not sure or if it is too dark to see, try replacing the suspected fuse with one of the same value that you know is good.
In case if you do not have a spare fuse, in an emergency you can pull out fuses, which may be dispensable for normal driving (for example, audio system, cigarette lighter, OBD, seat heater, and the like), and use it if its amperage rating is the same.
Notice
- Always switch off the ignition system and the affected electrical circuit before replacing a fuse.
- Always disconnect the battery before servicing high current fuses.
- Never use a fuse of a higher amperage rating than that indicated, or use any other object in place of a fuse, even as a temporary fix. This can cause extensive damage or even fire.
- If the replaced fuses blows again – contact a qualified and equipped service center.
