What is the Fuse all about?
Fuses, found in the fuse box, are low-resistance resistor devices that protect the circuits in the car from excessive current. Fuses are made to blow if the circuit gets more current than it is supposed to, protecting the circuit from the high current flow. There can be multiple fuses in multiple locations. The fuses should always be replaced with the specified fuse. All fuses come with the “AMP” value written on top of it. The fuse box will specify the correct value of fuse required.
Keep in mind:
If a fuse blows, is replaced, and then blows again, it indicates a problem with the electrical system. Something is causing the overload. Be sure to have the car inspected.
How it's done:
- Test fuses using a test lamp.
- Remove and replace the faulty fuse.
- Inspect fuse block for corrosion or melted holders.
Any time an electrical component of your vehicle stops working, you should schedule an inspection. There’s no way to perform regular maintenance on fuses, but they’re a straightforward and affordable repair when you notice that one is blown.
What common symptoms indicate you may need to replace the Fuse?
- One or more electrical components are not working (lights, radio, etc.)
How important is this service?
Fuses are resistors that send power to the electrical components of your car. Fuses receive a large amount of current, and lessen that amount of current before it is sent to each electrical part, so that the electrical components aren’t damaged by excessive power. When a fuse blows, electrical power will be not flow through it, and certain parts of your car will stop working. A blown fuse is unlikely to cause any damage to your vehicle, but the electrical components that rely on that fuse won’t resume working until the fuse is replaced.
