Understanding Your Car’s Electrical System and Fuses
Before we dive into the repair, it’s helpful to understand a little bit about how your car’s electrical system and fuses work. The fuse box is like a central protection system for all the electrical circuits in your car. It houses various fuses, each designed to protect a specific circuit from overloads that could cause damage. A fuse is essentially a sacrificial element, a small wire designed to melt and break the circuit if the current exceeds a safe level.
When a fuse blows, it means it has done its job by protecting the circuit from damage. Identifying and replacing the blown fuse is often all that’s needed to restore power.
Locating the Car Charger Fuse
The first step in fixing a car charger fuse is finding the right one. Here’s how:
- Consult Your Owner’s Manual: The most reliable source for this information is your car’s owner’s manual. It will usually have a diagram of the fuse box(es) and a list of which fuse corresponds to which circuit.
- Check the Fuse Box Cover: Many cars have a diagram on the inside of the fuse box cover itself.
- Look for Common Locations: Common locations for fuse boxes include under the dashboard (driver’s side or passenger side), in the glove compartment, or under the hood.
You’re likely looking for a fuse labeled “Cigarette Lighter,” “Accessory Power Outlet,” or something similar, as car chargers typically share a circuit with the cigarette lighter.
Inspecting the Fuse
Once you’ve found the fuse box and identified the correct fuse, it’s time to inspect it.
- Remove the Fuse: Use the fuse puller tool (often found in the fuse box cover) or a pair of needle-nose pliers to gently pull the fuse straight out.
- Examine the Fuse Wire: Look closely at the thin metal wire inside the fuse.
- If the wire is broken or melted: The fuse is blown and needs to be replaced.
- If the wire is intact: The fuse is good, and the problem lies elsewhere in the circuit.

Replacing the Fuse
If you’ve determined that the fuse is blown, replacing it is a straightforward process.
- Find the Correct Replacement Fuse: Use the amperage rating printed on the top of the blown fuse to find a replacement with the exact same rating. Using a fuse with a different amperage could lead to electrical problems or even a fire hazard.
- Insert the New Fuse: Carefully align the new fuse with the slots in the fuse holder and push it in until it’s securely seated.
- Test the Charger: Plug your car charger back in and see if it’s working. If it is, congratulations! You’ve successfully replaced the fuse.
Still Having Problems?
If replacing the fuse doesn’t solve the issue, you may have a more complex electrical problem, such as a short circuit in the car charger itself or the wiring. In these cases, it’s best to consult a qualified auto electrician to diagnose and repair the problem safely.
