The fuse boxes on a 2009 Honda Civic are located in two places: one engine-compartment fuse box on the driver’s side of the engine bay near the fender, and one interior fuse box inside the cabin on the driver’s side under the dash near the knee panel.
This article explains where they are, what they power, how to access them, and how to replace fuses safely. For the exact fuse map, refer to the diagram on each box cover or the owner's manual.
Engine compartment fuse box
The primary engine-compartment fuse box sits on the driver’s side of the engine bay, near the fender. It houses fuses and relays for major systems such as charging, starting, fuel, ABS, and other high-current circuits.
Access: Open the hood, locate the black plastic box with a lid labeled FUSE BOX. Lift the lid to reveal the fuses. A fuse puller is usually attached to the inside of the lid. Use it to remove or replace fuses, and always install a fuse with the same amperage rating.
- Identify the fuse you need by referring to the diagram on the inside of the lid or in the owner's manual.
- Pull out the faulty fuse with the fuse puller and replace with a fuse of the same rating.
- Close the cover securely and test the circuit.
The engine-compartment fuse box is best accessed with the hood up, and its map helps you target high-current circuits quickly.
Interior fuse box
The interior cabin fuse box for the 2009 Civic is located inside the car on the driver’s side, typically behind the lower dash panel near the knee area. The cover displays a diagram showing the blade fuses and their circuits.
Access: Remove the small access panel from the lower dash on the driver’s side to reveal the fuse block. A fuse puller is usually included on the inside of the cover. Replace fuses with the same amperage rating and ensure the cover is reinstalled securely.
- Fuses cover interior electronics such as power windows, interior lights, radio, and HVAC controls.
- Blade fuses correspond to circuits listed on the diagram—verify amperage before replacement.
- Recheck that the cover is seated properly after replacement.
Note: The interior fuse box is designed for convenience and is separate from the engine-compartment box, so repairing or replacing fuses should be straightforward with basic tools.
Summary
For a 2009 Honda Civic, you’ll find two fuse boxes: one in the engine compartment on the driver’s side of the engine bay, and one inside the cabin on the driver’s side under the dash near the knee. Use the diagrams on the lids to locate the correct fuse, replace it with the same rating, and secure the cover. When in doubt, consult the owner’s manual or a mechanic.
