- Turn off the ignition and disconnect the negative battery terminal.
- Locate the fuse panels. Most cars have two to three fuse boxes. The main fuse box is typically in the engine bay.
Your vehicle will also have an interior fuse panel under the dash or on the side of the dashboard.
It may also be behind the glove box, the rear seat, or the trunk.
- Look at the fuse panel to determine which fuse you need to check. Some car manufacturers display a fuse diagram on the back of the fuse covers. If you do not, look up a fuse chart online.
- Remove each fuse and inspect it to determine if the fuse is blown. A blown fuse will have a broken wire in the middle and most likely will be black.
Left – Good Fuse
Right– Blown Fuse - If you are looking for a specific fuse, look at the fuse chart and identify the location of the system in question.
The fuse chart is usually printed on the back of the fuse box cover, it may be a letter inserted in the fuse box, or some car manufacturers will include the fuse chart in the owner’s manual. - Replace the bad fuse. Once you identify the bad fuse, you need to replace it. Always replace fuses with the same ampere rating. The ampere rating is printed on the fuse and shown in the fuse chart. Don’t install a fuse that has a higher ampere rating. This can damage electronic components in your vehicle and possibly even fire in some cases.
