Protection of the electrical circuits of the vehicle is provided by fuses, circuit breakers, and fusible links; and the fuse blocks are located beneath the left-hand side of the instrument panel and in the compartment, within the guide on the cover. Every fuse is selected to safeguard a given circuit and the circuits are labeled on the cover of the fuse panel. The compact type has blade terminal configurations, are easy to install and replace; when an electrical part is not working, it is recommended to first check the fuse. With a test light, you can check for power where the terminal tips of the fuses are exposed and if there is power on one side of the fuse but not on the other side then this means that the fuse is blown and the evidence of this is seen by mere looking at the fuse where you will note that the element on the fuse is melted between the terminals. Replacing a fuse, one should use a fuse of the given type, as using the fuses of the different rating which are physically interchangeable is not advised given the requirement of certain levels of protection for every circuit, and the amperage value usually molded onto the body of the fuse. In case a fuse blows as soon as it is replaced, it should not be replaced again until the system condition that leads to Blown fuses, normally a short circuit due to a faulty wire is fixed. Moreover, some circuits are protected with fusible links, which apply in non-fused circuits, such as the high current side of the charging or starting circuits. Traditional inline fusible links have a larger part in the cable and are situated in their own block located within the engine compartment fuse and relay box; therefore, these cartridges are exchangeable for units with the identical amperage as soon as the negative battery terminal is disconnected.

Miniaturized fuses are employed in the fuse block. These compact fuses, with blade terminal design, allow fingertip removal and replacement. To check the fuses, turn the ignition key to the On position and, using a test light, probe each exposed terminal of each fuse. If the test light glows on both terminals of a fuse, the fuse is good. If power is available on one side of the fuse but not the other, the fuse is blown. A blown fuse can be easily identified through the clear plastic body by visually inspecting the element for evidence of damage.

Be sure to replace blown fuses with the correct type. Fuses of different ratings are physically interchangeable, but only fuses of the proper rating should be used. Replacing a fuse with one of a higher or lower value than specified is not recommended, as each electrical circuit needs a specific amount of protection. The amperage value of each fuse is molded into the fuse body.

If the replacement fuse immediately fails, don't replace it again until the cause of the problem is isolated and corrected. In most cases, this will be a short circuit in the wiring caused by a broken or deteriorated wire.
