The 2004 Honda Accord has two fuse boxes: one inside the cabin on the driver’s side under the dash, and one under the hood in the engine compartment on the driver’s side near the firewall. Use the diagrams on the covers to identify fuses and replace them with the correct amperage.
Interior fuse box (driver's side, under the dash)
Access and layout information before you inspect the interior box helps you locate it quickly and understand what each fuse controls.
- Location: Under-dash panel on the driver's side, typically near the knee area or door sill.
- Access: Remove the cover by prying gently at the edge to reveal fuses, a legend, and a small fuse puller tool if present.
- Fuse mapping: The lid interior shows fuse numbers and functions (e.g., radio, lights, power windows, horn).
- Amperage and replacement: Use the same amperage rating; if a fuse blows repeatedly, have the electrical system checked by a mechanic.
The interior fuse box is the first place to check for cabin-related issues, and its labeling is designed to make quick replacements feasible for the average driver.
Engine compartment fuse box
Under the hood, the main fuse/relay box sits in the engine bay on the driver’s side near the firewall or strut tower. The cover carries a diagram for quick reference.
- Location: Engine bay, driver’s side, near the firewall/strut tower area; the lid is typically labeled FUSE/RELAY.
- Contents: Fuses and relays for major systems such as engine management, ABS, charging, cooling fans, headlights, and horn.
- Identifying fuses: The cover diagram lists fuse numbers, amperages, and their corresponding functions.
- Replacement tips: Match the amperage rating exactly; avoid higher-rated fuses; disconnecting the battery is advised for some high-current fuses.
Keep the engine-compartment box cover in place and secure; use the built-in fuse puller or small pliers to remove fuses, and consult the diagram for correct replacements.
Summary
For a 2004 Honda Accord, there are two fuse boxes to know about: an interior cabin box on the driver’s side under the dash and an engine-compartment box on the driver’s side of the engine bay near the firewall. Always refer to the diagrams on the covers to identify and replace fuses correctly, and seek professional help if fuses keep blowing.
