What do fuses do?
Looking in the garage for a new fuse to replace a blown out headlight fuse? Over time, fuses have redesigned, and new ones have been invented. This means that old or universal fuses will probably not work in a newer vehicle. Additionally, fuses have a limited shelf life. For the most part, Mini fuses replaced the old, standard ATOs. Additional fuses called Maxis, as well as vehicle-specific fuses, complete the fuse repertoire in today's cars.
How do I know I have a blown fuse?
A blown fuse can leave a vehicle with no lights, turn signals, stereo system, etc. If all but a few electrical accessories work, there is probably a bad fuse. Once the fuse associated with the inoperative component is identified, the fuse can be removed and replaced. A fuse that repeatedly blows out may be an indicator of a more serious electrical problem.
What are my options?
The vehicle can either be taken to a local dealer or repair shop, or the owner can replace a fuse. There are automotive and other websites that explain how to replace fuses. In addition to some free how-to instructions online, numerous vendors sell fuses for a wide variety of makes and models.
