How to Change a Car Fuse

Having a blown fuse usually means there has been a circuit overload in your vehicle's system. It's much like changing one in your home. It may take a little patience to get the job done, but it's a simple procedure if you use these simple pointers.

First Things First

1. Be sure you have the vehicle ignition in the off position. 
2. Check the owner's manual to locate the fuse panel. In most vehicles, it will be under the steering wheel. However, some vehicles may have two, with another one under the hood.
3. Remove the cover to the fuse panel. A diagram of each fuse and its amperage is usually located on the flip side of the cover. The panel will have various numbers and colors to indicate the size of the fuse. Be sure to double check the diagram in case someone else has replaced the wrong fuse. This could be one of the reasons it is blown.
4. Check the metal filament in each fuse using a flashlight if it is dark to make the numbers more visible. If the inside is black, the filament might be broken. 

Changing the Fuse

Pry up one end of the fuse cap to avoid breaking the fuse. You may have to go toward the center at the end of the fuse to make it move. You can use a fuse puller or your hands to pull out the fuses. Most vehicle manufacturers will provide a puller in the fuse box. You can also use a pair of pliers, a screwdriver, or a bent paper clip. Use caution because they will break easily. It is a simpler procedure if you don't break the fuse in the panel.

Use the same amperage for the fuse that is being replaced. You could cause electrical damage if the same amp is not used. However, for an emergency situation, you can use a fuse that is not used in another function if it has the same power amperage. For example, you could use one that is for your windows if you need one for your windshield wipers in the rain. It is a good idea to keep a variety of fuses for emergencies. You can purchase a kit in the automotive section of any store that sells automobile products. 

These guidelines should be all you need for replacing your vehicle's fuse. However, if you change the fuses and the problem isn't fixed, it may be time to consult a mechanic, such as Dugan Oil and Tire. It might be a more serious problem that will need a professional.
