Most vehicles contain a dashboard light fuse which is used to power the lights on the dashboard. Depending on the make and model of the vehicle, this fuse may be located in several different locations, such as under the hood or in one of the side panels. It's typically easy to identify when you look for a small round black device that looks like a battery. It's important to find and replace any blown fuses, as they can cause your vehicle's dashboard lights to malfunction or stop working altogether.
