There are two fuse boxes: one in the engine compartment (under the hood) and one inside the cabin (under the driver’s dash).
Knowing their exact locations helps you quickly diagnose electrical issues, locate the correct fuses, and replace blown fuses safely. Below is a guide to where they are and how to access them in a 2017 Civic.
Engine compartment fuse box
The engine compartment fuse box sits on the driver’s side of the engine bay, near the firewall. The lid is labeled FUSE/RELAY BOX and includes a diagram on the underside that lists each fuse and relay.
- Open the hood and locate the black plastic fuse box cover on the driver's side of the engine bay near the firewall.
- Remove the cover and consult the diagram on the underside to find the fuse you need.
- Use the fuse puller (often built into the box) to remove the fuse. Check the metal strip inside; if it’s blown, replace it with a fuse of the same amperage rating.
- Reinstall the fuse, reseat the cover, and close the hood. Start the car to test the circuit.
The engine bay fuse box contains high-amperage fuses and relays for critical systems such as powertrain and essential electronics. Handle carefully and refer to the owner’s manual for exact amperage ratings and circuit designations.
Interior fuse box
The interior fuse box is located under the driver's side dash, behind a removable cover. It houses fuses for interior electricals such as power windows, door locks, instrumentation, and climate controls.
- Slide the interior fuse box cover out or remove the panel to expose the fuse block and the diagram on the inside.
- Identify the fuse you need using the diagram, then pull the blown fuse out with the fuse puller or a pair of needle-nose pliers.
- Replace it with a fuse of the same amperage rating, ensuring the fuse seats fully. Reattach the cover when finished.
- Test the affected system (e.g., windows, lights, or HVAC) to confirm the fuse replacement worked.
If a fuse continues to blow after replacement, there may be a short or excessive draw somewhere in the circuit. In that case, have a professional inspect the electrical system to prevent further damage.
Summary
In a 2017 Honda Civic, the two primary fuse locations are the engine compartment (under the hood, driver’s side near the firewall) and the interior fuse box (under the driver's dash). Access is straightforward with the diagrams on the covers guiding fuse identification. Always use the correct amperage when replacing fuses and consult the owner's manual for detailed circuit information. If electrical issues persist, seek professional assistance.
