To protect the car circuits there are fuses and fusible links utilized, and the fuse box can be found in the side panel behind the driver's dash kick panel on the right side. The first step is to remove the fuse that is under suspicion of being blown by pulling it out of the panel, then, looking at the curved and metallic part contained in a plastic housing to determine if the element is damaged; if it is, then the fuse is defective and must be replaced. Each of them has reference to the circuit it protects as labelled on the fuse cover, and replacement should be made with the correct fuse since various electrical circuits in a car need different levels of protection depending with the amperage rating necessary for the circuit. Choosing a wrong fuse means that a fuse with a low amperage rating will blow before the circuit is quite through, on the other hand, a fuse with high rating will not blow within time to save the circuit from major damage. Laying metal on a fuse or using foil threatens the electrical system and the entire system will be damaged. If the replacement fuse blows as soon as it is fitted, the fuse should not be replaced until the probable cause of a short circuit, usually by a separated or corroded wire, is isolated.
