![]() If the defect is not visually apparent, test it with a standard automotive test light or a fuse-testing tool mostly available in auto parts stores. The fuse looking anything like any of these descriptions would necessitate a fuse replacement. Look at the metal filament and see if it is black, fused, broken, or burned through. Once you have figured this out, visually inspect the fuse in question. Refer to the diagram inside the fuse box lid/cover to locate the defective fuse. Additionally, use a plastic bag/container or a magnetic tray to keep loosened bolts together until you need to use them to replace the fuse box housing to where it was. So, keep an eye on the placement of each bolt as you individually remove them. Pay attention to the retaining bolts holding the fuse panel in place – they may be different lengths. Tip: Tape and label them for easier reinstallation and preventing crossed wires. Doing so exposes the many wires connected to the fuse box and routed to various systems and sensors that make vehicle components work. Removing the fuse box housing (wiring harnesses and all) is key. Remove the Fuse Box Housingĭepending on the problem, you may need to remove the fuse box altogether. The fuse box power supply is most likely a single or set of red wires with a terminal connected with a bolt (looks pretty similar to a battery). ![]() You may need to remove its housing first to access the wires, then circle back to the power supply before moving on. But to be doubly sure no live current is going through the systems, it would be best to disconnect the power supply once the fuse box lid is off and set aside. This step usually only applies when needing to remove the entire fuse box. These color codes and amperage ratings are utterly important to note, especially when you have already pinpointed the fuse at fault and are about to get it replaced. Likewise, you will see several color-coded fuses with numbers denoting their specific amperage rating. Turning over the lid of your fuse box should unveil a fuse diagram showing which fuse works with which electrical component – this is an excellent reference as you test and troubleshoot the blown fuse later on. Moreover, not all vehicles have both an in-cabin fuse box and one that sits under the hood. However, the location of the fuse box varies from car to car. Most vehicles have their fuse panels under the steering wheel (or somewhere near it). Locate the Vehicle’s Fuse Boxīeginners need not feel intimidated when locating the fuse box or panel, as the service manual typically specifies its location. This step is especially crucial for vehicles equipped with a push-button start system. Doing this guarantees that no electricity will be running through the system as you inspect, test, and change any blown fuses. Then, using a socket wrench like Hazet 854T Socket Wrenches (view on Amazon) or adjustable wrench, disconnect the negative terminal attached to the battery (set it aside where there is no contact with any metallic object). First, make sure that your car is not running. Mishaps can happen, especially when dealing with your vehicle’s electrical system. How to Remove a Car Fuse and Replace It – 12 Steps 1. Still, it is always a good idea to side with caution and check. ![]() Gradually worsening symptoms may not necessarily be associated with a blown fuse. Characteristically, telltale signs indicative of a faulty fuse happen suddenly.
