How to Tell if You Have a Blown Fuse How to Tell if You Have a Blown Fuse

When a system in your car begins to malfunction, one of the first things you should do is check to see if you have a blown fuse. This could save you lots of money, avoiding a trip to the mechanic. If a fuse blows again after being replaced it is likely a sign of a more serious problem. In this case, making the trip to the mechanic is recommended.

Find the Fuse Box

The first step is to locate your vehicle's fuse box. Most cars have two, one under the hood and one in the passenger cab underneath the steering wheel. The fuse box in the cab usually protects smaller systems like the stereo, while the fuse box under the hood protects larger systems. If you have trouble locating the fuse box, consult your owner's manual.

Locate the Blown Fuse

Next, check the owner's manual for a diagram of the fuses and which fuses correspond to which electrical systems. Once you have determined which fuse is associated with the problematic system, firmly pull it out using a pair of pliers or a fuse puller.

Replace the Fuse

If the small metal piece in the middle of the fuse is broken, you have a blown fuse. When replacing the fuse, make sure you buy a new one that is exactly the same as the old one. The owner's manual should contain information on each fuse for easy reference.
