Locating and inspecting the fuse boxes is the first step when a feature like headlights, the radio, or power windows stops working. In brief: locate the interior and under-hood fuse boxes, inspect each fuse for signs of damage, and replace blown fuses with the correct amperage. If fuses keep blowing, there may be a wiring fault or short that needs deeper diagnosis.
Where fuses are located in a Honda Accord
Most Accord models use two main fuse boxes: an interior fuse box and an under-hood fuse box. Some trims also have a fuse box in the trunk. Exact locations vary by year and trim, so always consult the owner’s manual or the diagram on the fuse box lid for your specific car.
Interior fuse box
The interior box is usually under the driver's side dash or behind a panel near the knee area. In some years, there is also a fuse box inside the glove box. The lid or the manual includes a diagram showing which fuse protects each circuit.
Under-hood fuse box
This box sits in the engine bay near the battery or firewall and houses fuses for engine management, lighting, and other major systems. Use the lid diagram to identify the fuse for the affected circuit.
How to check fuses: step-by-step
Follow these steps to inspect and test individual fuses without causing damage. Gather a fuse puller or insulated pliers and a multimeter if you have one.
- Identify the fuse associated with the affected system using the diagram on the fuse box lid or in the owner’s manual.
- Carefully remove the fuse using a fuse puller or insulated tool.
- Visually inspect the fuse for a broken filament or discoloration indicating a blow.
- If you have a multimeter, test for continuity across the fuse’s contacts. No continuity suggests the fuse is blown.
- Replace with a new fuse of the same amperage rating listed for that circuit.
- Reinstall the fuse fully and test the system to confirm it’s working.
When replacing, ensure you use the correct amperage rating. A fuse that is too high can fail to protect the circuit, potentially causing wiring damage.
What to do if a fuse keeps blowing
If a fuse continues to blow after replacement, don’t keep replacing it. A repeated blow often signals a short or overcurrent in the circuit, or a faulty component.
- Disconnect the suspected load or accessories connected to that circuit and test again.
- Inspect wiring for signs of wear, chafing, or aftermarket modifications that might cause a short.
- Check for corroded grounds or loose connections.
- Consider seeking a professional diagnostic to trace the short and prevent electrical damage.
Proceed with caution: electronics and airbags rely on stable power; if you’re unsure, seek professional help.
Safety considerations and tips
Always turn off the ignition and remove the key before inspecting fuses. Use insulated tools, and never bypass a fuse with a wire or metal object. Keep a small supply of spare fuses in the correct ratings in your vehicle for quick replacements.
Summary
To check fuses in a Honda Accord, locate the interior and under-hood fuse boxes, reference the diagram to identify the circuit, remove and inspect the fuse, test with a multimeter if available, and replace with a fuse of the same amperage. If fuses repeatedly blow, inspect for shorts or wiring issues and seek professional assistance to avoid damage and safety risks.
