Knowing how to fix a cigarette lighter fuse in your car is a surprisingly useful skill. Not only does it restore power to your 12V outlet (often mistakenly called the cigarette lighter), but it can also prevent further electrical issues. This guide will walk you through the process, from diagnosis to replacement.
A blown cigarette lighter fuse is a common problem, and thankfully, it’s usually a simple fix. Maybe your phone charger shorted out, or you overloaded the circuit with too many devices. Whatever the reason, identifying and replacing the fuse is straightforward with the right tools and a little know-how. If you’ve ever wondered how to tackle this issue yourself, this guide is for you.
Locating the Fuse Box
The first step in fixing your cigarette lighter fuse is finding the fuse box. It’s often located under the dashboard, in the glove compartment, or under the hood. Your car’s owner’s manual is your best friend here – it will tell you precisely where the fuse box is hidden. If you are having problems with your car lock, you can find more information about how to fix your car door lock on our website.
Once you’ve located the fuse box, open it up. Inside, you’ll find a variety of fuses, each responsible for a different electrical circuit in your car. The cover of the fuse box or the owner’s manual typically has a diagram that identifies each fuse and its corresponding circuit. Look for one labeled “cigarette lighter,” “12V outlet,” or “power outlet.”
Identifying the Blown Fuse
Now that you’ve found the right fuse, it’s time to see if it’s blown. A blown fuse will have a broken filament, often visible as a dark or metallic break inside the fuse. If you have trouble seeing it, you can use a fuse tester or a multimeter to confirm. You might be interested in where to fix car door lock if you’re facing lock issues.
Replacing the Fuse
Once you’ve confirmed the fuse is blown, it’s time for the replacement. Using the fuse puller (often located in the fuse box or with your car’s tools), carefully remove the blown fuse. Make a note of the amperage of the blown fuse—it’s usually printed on the top—and make sure the replacement fuse has the same amperage. Inserting a higher amperage fuse can be dangerous and lead to electrical damage. If you’re unsure about what you’re doing, seeking professional help is always a good idea. Sometimes, the problem may not be with the fuse, but with the lock mechanism itself. Check our guide on how to fix a broken car door lock for further assistance.
Insert the new fuse into the empty slot and make sure it’s securely in place. Close the fuse box, and test the cigarette lighter or 12V outlet. If it’s working, congratulations! You’ve successfully replaced the fuse. Learn how much to fix car door lock if you have other car issues.
