Two fuse boxes power the Civic’s electrical system: one inside the cabin and one in the engine bay.
Interior fuse box location
The interior (cabin) fuse box is located on the driver’s side under the dash, behind the knee bolster. A removable cover bears a diagram showing which fuse protects each circuit.
To access and inspect the interior fuses, follow these steps:
- Open the driver’s door and slide into the seat. Look under the dash to the left of the steering column for the panel covering the fuse box.
- Gently pry off the panel or pull it away to reveal the fuse box.
- Remove the fuse box cover and read the diagram on the inside to identify the fuse you need.
- Use a fuse puller or your fingers to remove the faulty fuse and replace it with a fuse of the same amperage rating.
- Reinstall the fuse, then snap the cover and panel back in place.
The interior fuse box handles many common electronics and accessories, such as lighting, courtesy lights, power windows, and infotainment-related circuits. Replacing fuses with the correct rating helps prevent electrical issues.
Engine compartment fuse box location
The engine compartment fuse/relay box sits in the engine bay on the driver’s side area of the front, under a removable lid. The lid carries a diagram that identifies each fuse and its amperage.
To access and inspect the engine bay fuses, follow these steps:
- Open the hood and locate the engine compartment fuse/relay box (a rectangular box with a removable cover on the side of the engine bay).
- Release the latch or clip and lift the cover to expose the fuse layout.
- Check the diagram on the underside of the lid to find which fuse protects the circuit you’re troubleshooting.
- Pull the faulty fuse straight out and insert a replacement with the same amperage rating.
- Secure the lid back on the box and close the hood.
Typical engine bay fuses cover higher-current circuits and components such as the main power supply, charging circuit, and engine management systems. Always match the amperage when replacing to avoid damage.
Additional guidance
If you’re unsure which fuse to replace or the diagram isn’t clear, consult the 2017 Honda Civic owner’s manual or contact a Honda service center. Fuse diagrams can vary by market and trim level, so referencing the exact model’s documentation is the safest approach.
Summary
For a 2017 Honda Civic, there are two fuse boxes: one inside the cabin (driver’s side under-dash) and one in the engine bay (fuse/relay box). Accessing them involves removing their respective covers and using the diagrams inside to identify the correct fuse. Replace fuses with the same amperage rating and reassemble everything securely. If in doubt, consult the owner’s manual or a dealership for precise mappings.
