A fuse box layout is different for every vehicle, but the actual fuse box layout on a specific car can normally be identified by checking the lid. Car manufacturers typically place a chart on a fuse box lid that details the arrangement of the fuses, the amperage of each fuse and which electrical system is powered by each one.
Most modern vehicles have two fuse boxes: one in or around the instrument panel, and another in the engine compartment. Checking the fuse boxes is often necessary in case of electrical component failure. A burnt fuse is easy to recognize, and replacing it is a fairly simple matter, so car owners should take the time to get to know their fuse boxes should the need arise.
A faulty fuse must first be identified before a car owner proceeds with fuse replacement. These can be easily identified by a broken filament or blackness inside. Most car manufacturers provide a plug puller for the removal of fuses, and these are often placed right inside the fuse box. Once all the broken fuses have been replaced, the next step is to test the malfunctioning system to confirm that the problem has been solved. If the issue persists, it may be time to call in a professional auto technician to handle the repairs.
