Every car owner should know that after long use of the car, one or more of your automotive fuses will definitely blow.

But before solving any issue, we have to know what the problem is and how to prevent it. So you need to have some idea about the car Fuse.

What is a Car Fuse?

Car Fuses are automotive electric fuses that protect a car’s electrical components and wiring. The Fuse is also known as electric circuits that use less than 32-volt direct current. So it safeguards from overflowing current or short-circuiting. This electronic system distributes powers in different parts such as Transmission electronics, Chassis Electronics, Engine electronics, Entertainment systems, etc. You can find mostly three types of car fuse in the market.

  •  Metal ends Cylindrical glass fuses.
  • Square plastic fuses that have two metal prongs
  • Filament less Cylindrical plastic fuses that comes without a cover

If your car’s fuse has blown, it indicates that there was a contact between two wires and occurs a short-circuit. So a car fuse is a safety device that is designed to blow to keep your electrical components safe from short-circuit.

Blown Fuse In Car Symptoms

Every car uses a fuse, and if your vehicle has an electrical issue, it could be as a result of a fuse that has heated up, melted, and in the end, interrupted the flow of electricity. At times, a blown fuse depicts a larger issue, but they as well blow for small reasons, such as the driver overloading the system by utilizing every available accessory at the same time. The fuse can as well blow if they are past their best before date. Some other sign you should check is your car’s fuse is blown by excessive current.

  • The most common sign is there will be no power or lights on your dashboard. Headlight and indicator lights also stop working.
  • In some cases, the blown fuse window glass tube looks cloudy or brunt. So you might get the smell of burnt wire.
  • The washer motor and windshield wiper won’t work properly as they draw too much current

Furthermore, fuses can also be blown if a person has changed a bad fuse with one that has greater amperage. The most common amperages are as follows: 15, 20, and 30, and thus changing a 15 amp fuse with a 20 or 30 amp fuse or vice versa may lead to a blown fuse. Moreover, this could lead to a more grievous car electrical issue because it can cause wires to melt. Also, replacing a higher amp fuse with one of the lower amperages will likely not power the component that is not functioning.

Summary

In case you are in doubt that you have an electrical issue with your car, a professional mechanic can diagnose the issue and state if it’s a bad fuse or some more serious problem with the car. If it’s a bad fuse, ensure that it is replaced with a new one that has the same amperage.
