The fuse for the cigarette lighter on a 2012 Honda Civic is located in the interior fuse box on the driver's side under the dash. It is labeled “CIG” and usually uses a 15-amp fuse.
In this article, we explain exactly where to find the fuse, how to inspect and replace it, and what to do if the outlet still doesn’t work after replacement.
Fuse location and identification
The interior fuse panel is mounted under the left side of the dash near the driver's knee. Accessing it typically requires opening a small panel or cover. The fuse diagram is printed on the panel cover or shown in the vehicle’s owner’s manual, with the cigarette lighter fuse labeled as CIG or similar.
Here is what you should know about locating and identifying the cigarette lighter fuse.
- Access the interior fuse box from the driver’s side, usually by pulling a panel open near the knee area.
- Look for a fuse labeled “CIG,” “CIG OUTLET,” or “CIG LTR” on the diagram inside the panel cover.
- The standard rating for the Civic’s cigarette lighter fuse is typically 15 amps.
- Use the exact fuse type specified by Honda (blade-type fuses are common on this model).
If you can’t locate the diagram on the panel, or your trim uses a different labeling, consult the owner’s manual for the precise fuse location and rating.
How to inspect and replace the fuse
These steps guide you through checking whether the CIG fuse is blown and replacing it safely.
- Turn off the ignition and remove the key, then disconnect any devices plugged into the cigarette lighter.
- Open the interior fuse panel and locate the fuse labeled “CIG” on the diagram.
- Carefully pull the fuse straight out using fingers or a fuse puller.
- Inspect the fuse: a blown fuse typically shows a broken metal link or a darkened appearance.
- Replace with a new fuse of the same amperage, usually 15A, ensuring you use the same type and rating.
- Reinsert the fuse fully and close the fuse panel cover.
- Test the cigarette lighter by plugging in a known-good device to confirm it’s working.
Note: If the new fuse blows again, there may be a short in the outlet, an overcurrent condition from a device, or an issue with wiring. In that case, consider professional inspection to prevent electrical damage.
When to seek professional help
If replacing the fuse repeatedly fails to restore function, or if you notice burning smells, melted plastic, or damaged wiring, a qualified technician should diagnose the electrical circuit to prevent further problems.
Summary
For a 2012 Honda Civic, the cigarette lighter fuse is typically a 15-amp fuse labeled “CIG” located in the interior fuse box under the driver’s side dash. Access the panel, identify the CIG fuse, and replace it with a fuse of the same rating if blown. If the new fuse blows again, there may be an issue with the outlet, wiring, or an attached device, and professional service is recommended. Always refer to the owner’s manual for exact labeling and location for your trim level.
