How do I … Change a blown fuse in my vehicle
Like in your home, your car uses fuses to help prevent damaging to its electrical systems, and these can blow on occasion. Changing a blown fuse is easier than you think and is similar to how you would do so at home.
The first thing you need to do is to locate your fuse panel. Many cars have two fuse boxes, one located under the hood that helps to protect engine components, and the other in the interior of the vehicle – many times located around the steering wheel or dash – that relates to features like the radio or an interior light. Some vehicles do have additional fuse boxes. Your owner manual will help you to locate how many you have, where they are and how to access them.
The manual will also include a diagram that helps identify what fuse protects which component of your vehicle. Similar information will also be included on the interior of the cover of the fuse panel, with details specific to what the fuses located there do.
Using this information, you can locate the blown fuse related to the issue you are experiencing. When you locate it, you may notice the fuse’s filament is broken of the inside has blackened. You can then use needle nose pliers to remove it. You can also remove it with your fingers. Be careful to not break the fuse as it might become more difficult to remove it from the panel.
Once the fuse is removed, you can replace it with a new one. It is important you replace the fuse with one featuring the same amp. Never replace a blown fuse with a higher amp. Most fuses used in a vehicle are 10 to 30 amps. The information on which is the correct one you should use for that component will be included on the panel or in the owner manual. Place the correct fuse in place, and then start your vehicle’s ignition to confirm the problem has been resolved.
Many stores sell assorted packs of fuses, so you can keep these in your vehicles in case you need them for another issue. If you fuse blows again, or the component it relates to still does not work, you will want to bring it to a mechanic to take a closer look at the issue.
