There are two fuse boxes on a 2006 Honda Civic: one in the engine compartment and one inside the cabin. The engine bay box protects essential systems, while the interior box covers cockpit and lighting circuits.
Fuse box locations
The following outlines where to locate the two fuse boxes and how they are typically accessed on a 2006 Civic.
- Engine compartment fuse box (under-hood): located in the engine bay on the driver’s side, toward the rear of the area and near the firewall. It is covered by a plastic lid labeled Fuses/Relays and includes a diagram for quick reference.
- Interior fuse box (cabin): located behind the left side dash panel near the driver's knee area. Access usually requires opening the driver’s door and removing the cover or a small panel to reveal the fuse box and its diagram.
Both boxes are clearly labeled with a diagram inside the lid, showing which fuses control major systems and accessories, and the interior box typically serves lighting, interior accessories, and certain cockpit circuits.
Accessing and identifying fuses
When you need to inspect or replace a fuse, begin with the box you suspect supplies the affected system. Use the fuse puller provided in the box or a pair of small pliers to remove the fuse, then check for a broken filament or a darkened appearance. Replace with a fuse of the same amperage rating as specified on the diagram inside the lid. Always turn off the ignition and electrical accessories before removing fuses to avoid damage or injury.
What to do if you can’t locate a fuse box
If you have trouble finding one or the cover is missing, refer to the owner’s manual for the exact fuse box diagrams and locations. You can also check reputable online diagrams or contact a Honda dealership or qualified mechanic for guidance. Never force a panel or ignore a label—misidentifying a fuse can lead to electrical damage.
Summary
The 2006 Honda Civic uses two fuse boxes: an engine compartment box on the driver’s side near the firewall and an interior box behind the left dash. Each box features labeled diagrams to help you identify the correct fuse, and proper procedure involves using the provided fuse puller, replacing with the same amperage, and safely disconnecting power before handling fuses.
