Fuses protect the electrical devices in your vehicle from experiencing damaging power surges. That means, if there is an unexpected surge in your vehicle, the fuse will blow (instead of your infotainment system).
If your vehicle is having electrical problems that are resulting in extra energy and blown fuses, it’s important that you determine the root cause of the issue before installing a new fuse; otherwise, you will have to keep making the same repair.
Once you’ve done your due diligence by pinpointing the issue yourself or consulting a local mechanic, you’ll need to install a replacement fuse. Here’s what you need to know.
Locate the fuse panel
The first step is locating the fuse box (which holds the fuse panel). The exact location can vary depending on the model. Some common places include: underneath the steering wheel, under the glove box, or under a seat.
If you’re having trouble locating your fuse box, consult your owner’s manual.
Remove the fuse box cover
Remove the fuse box cover or case. There should be a diagram on the front or on the back of the cover explaining what each fuse powers.
Identify the blown fuse
By noticing which fuse is blackened or has a broken metal filament, you should be able to determine which fuse has blown.
Remove the fuse
Gently pull the fuse out. You shouldn’t need any special equipment; simply pinch it with your fingers. Make sure not to apply too much force or you could risk breaking it.
Find a replacement
Take the broken fuse to an auto parts store to see if they have the specific replacement fuse you need. You could also look at the specifications in your owner’s manual and purchase one online.
Replace the fuse
Once you have purchased the appropriate replacement, slot it into the place where the old one used to be and push down until it’s secure.
Turn on the car
Turn on your car and make sure everything is working correctly. Check everything that needs power to operate. Don’t forget the windshield wipers, radio, interior lights, fans, window power, etc.
Replace the fuse box cover
Now that you’ve made sure everything is working the way it should, it’s time to put the cover back in its place. You have successfully replaced a broken fuse!
If replacing the fuse doesn’t work
If the stops working again or if you can’t get the replacement to work at all — seek professional help. In this scenario, it will most likely mean that you used the wrong fuse specifications when changing it.
While changing a fuse can be a simple project, don’t get discouraged if it doesn’t work the first time. Taking the time to learn and try again will be worth it once you see the time, effort, and money you can save when you learn how to execute simple car-maintenance tasks on your own.
