There are two fuse boxes on a 2012 Honda Accord: one under the hood in the engine compartment and one inside the cabin on the left side of the dash.
These boxes protect the car’s electrical circuits. The exact fuse layout and amperage ratings are printed on the lid diagrams and outlined in the owner's manual, so consulting those references is recommended when diagnosing issues.
Engine compartment fuse box
Location and access
The engine compartment fuse box is located on the driver’s side of the engine bay, toward the front of the car. It is a rectangular black box with a removable lid labeled FUSE/RELAY.
To access the fuses, follow these steps:
- Park the car, turn off the engine, and set the parking brake; open the hood.
- Locate the engine compartment fuse box on the driver’s side near the strut tower.
- Remove the box lid by pulling the tab or lifting at the edge.
- Refer to the fuse diagram printed on the inside of the lid to identify the fuse you need.
- Use the fuse puller (often stored inside the box lid) to remove a suspected blown fuse and inspect it.
- Replace any blown fuse with one of the same amperage rating, then reseat it firmly.
- Snap the lid back on and close the hood.
After performing replacement or inspection, ensure all connections are secure and that the diagram on the lid matches the function you’re addressing.
Interior fuse box
Location and access
The interior (cabin) fuse box is mounted inside the vehicle, on the left side of the dash. Access typically involves removing a small panel or knee-side cover near the driver’s footwell or the hood-release area.
To access the interior fuses, follow these steps:
- Enter the car and locate the left side of the dashboard under the steering column; remove the panel or cover to reveal the fuse box.
- Check the diagram printed on the fuse box cover or panel to identify the specific fuse you need.
- Use the included fuse puller to remove a suspected blown fuse and inspect it.
- Replace blown fuses with the correct amperage rating as indicated by the diagram.
- Reinstall the panel securely and verify that all functions return to normal.
Keep in mind that interior fuses control many comfort and convenience systems, such as lights, power windows, and radio; if a fuse keeps blowing, there may be a short or another electrical fault that merits professional inspection.
Safety and maintenance tips
Always replace fuses with the same amperage rating specified for the circuit. If a fuse blows repeatedly, don’t keep replacing it—diagnose the underlying issue or consult a qualified technician. When working on the fuse boxes, disconnect the battery if performing more extensive electrical work, and replace the lid or panel securely after maintenance to protect the wiring from damage.
Summary
The 2012 Honda Accord houses two fuse boxes: one under the hood in the engine compartment and one inside the cabin on the left side of the dash. Access each box by removing its cover, consulting the diagram for fuse placement, and replacing blown fuses with the correct amperage. For persistent electrical problems, refer to the owner’s manual or seek professional service to avoid further damage.
