The fuses are located in two main places: inside the cabin under the driver’s dash and in the engine compartment on the left side of the engine bay. Each fuse box cover includes a diagram showing which fuse protects which circuit.
Interior fuse box (under the driver’s dash)
The interior fuse box is usually tucked under the dashboard on the driver's side, behind a removable cover. Access may require pulling back a knee bolster panel or reaching under the dash to release the cover. The cover backside typically features a diagram that maps each fuse to its function.
These fuses protect interior and auxiliary systems that you interact with daily. The following overview helps identify what you’ll commonly find in this box:
- Fuses for interior lighting and dash illumination
- Power windows, door locks, and mirror controls
- Audio system, radio, and any navigation components
- HVAC controls and blower motor
- Accessory outlets and miscellaneous electronics
- Cruise control electronics (if equipped)
Refer to the fuse box cover for exact fuse locations and amperages. Replace a blown fuse with one of the same amperage, and if fuses blow repeatedly, have the circuit inspected by a professional.
Engine compartment fuse box
The second fuse box is in the engine bay, typically on the left side near the firewall or along the top edge of the engine compartment, protected by a removable cover with a schematic. This box holds higher-current fuses and relays essential to the vehicle’s operation.
Key circuits commonly protected here include the major power trains and electrical systems that demand higher current:
- ECU/engine management and related power fuses
- Fuel system and injector circuits
- Ignition/starting circuit fuses
- Cooling fan and radiator-related relays
- High-current circuits such as headlights, horn, and other major components
- Charging system and battery-related circuits
As with the interior box, use the same amperage rating when replacing fuses. If a fuse keeps blowing, stop and diagnose the culprit—faulty wiring, a bad component, or a short can be the cause and may require a technician’s diagnosis.
How to check and replace fuses
Most fuse boxes include a built-in fuse puller or you can use insulated pliers. With the engine off, gently pull a suspect fuse straight out to inspect it. A blown fuse will have a broken filament or appear discolored/dark. Replace it with a fuse of the exact amperage rating indicated on the fuse box cover or lid.
After replacement, test the related function to confirm operation. If the new fuse blows again, discontinue use of that circuit and seek professional service to diagnose wiring or component issues.
Summary
For a 2011 Honda Accord, the fuses are primarily located in two places: the interior fuse box under the driver’s dash and the engine compartment fuse box. Each box has a diagram that maps fuses to specific circuits. When replacing fuses, always match the amperage rating and consult a technician if fuses continue to blow. This quick reference helps you quickly locate and inspect fuses to keep the vehicle running smoothly.
