How to Find/Replace a Blown Fuse in Car

 

Does your radio not turn on? Are you unable to use your cigarette lighter in your vehicle? You could be experiencing electrical problems. The solution could be as simple as a blown fuse.

A fuse does not specifically control any aspect of your car, but it acts as a bridge between electrical components and battery. When an electrical component has too much electricity flowing through it the fuse is designed to melt. When a fuse melts it is preventing your vehicle from greater damage such as engine damage or a fire catastrophe. When a fuse blows, it must be replaced before the circuit will work.

How do I know a Fuse is damaged?

There are a few methods to identify a damaged fuse. The most obvious way is that an electrical component will stop working. You can also visually inspect the fuse. One of the methods is to use a tool called a multimeter which measures the electrical current or voltage. If you do not have access to a multimeter you can examine the fuse. All you have to do is simply remove the fuse from the compartment and if you see black residue or the middle strip of metal is broken; you have a damaged fuse.

Importance of a fuse box cover:

The fuses in your car play such an important role in the electrical component of your vehicle. It is essential to protect the fuse box. You will notice that a fuse box sometimes contains two covers. The biggest culprit in damaging a fuse box is water. If water leaks into the fuse box it can damage the fuses. Moisture can seep into the fuse box of older vehicles and cause corrosion. It is vital to occasionally check your fuse box and clean it if signs of corrosion appear.

Step 1: Check your Owner's Manual for the location of your fuse box. You could possibly have two boxes containing fuses. For example: a Toyota Tundra will have a fuse box under the hood and another below the dashboard on the driver's side. In our video the fuse box is located on the driver's side. Once you have located the box, open it.

Step 2: Check the Owner's Manual for the Specific Fuse you need to replace. You should look at the chart until you have arrived to the correct fuse number, then glance at the diagram for the specific location of that fuse number.

Step 4: Using a brand new fuse of the same rating/amperage insert the unbroken fuse into the same socket where you pulled the damaged fuse from. To ensure the fuse is seated properly, make sure the Amperage number can be read as this will guarantee you are placing the fuse in the correct way and not upside down.

TIP: To identify a fuse of the same rating/amperage it will most likely be the same color.

Step 5: Replace the Fuse Cover back on the box.

Step 6: Check the troubled circuit by turning on the ignition and then test out the circuit to ensure it is working properly.

TIP: The majority of fuse covers will have a slot to place new and unused fuses. You should keep a few in storage in case of emergencies.

If by chance the damaged circuit does not work after replacing the fuse, then the problem may be greater.

When you become the owner of a vehicle, your best practices will include prevention and preparation. Do your part to prevent any major damage to your car by continually checking it and getting routine maintenance done. Be prepared, accidents and issues can arise at any moment. Keep bottled water in the trunk of your car for emergencies and extra car fuses tucked away in the fuse box, as well as flashlights and other necessary items at hand.
