The interior fuse box is located on the driver's side under the dash, in the knee area, behind a small removable panel.
For the 2003 Accord, access typically comes from removing the knee bolster on the left side of the driver’s footwell. The fuse box cover carries a diagram showing which fuse protects each circuit, and fuses are replaced with the same amperage rating. Always ensure the ignition is off and the parking brake is set before handling fuses.
Location and access
The interior fuse box sits within reach of the driver, tucked inside the lower dash at the left side of the steering column. To expose it, you’ll need to remove a small panel (the knee panel or knee bolster) that covers the fuse box and its cover, which is labeled with circuit information.
To reach it, follow these steps:
- Park on a flat surface and turn off the engine. Remove the key from the ignition and set the parking brake.
- Open the driver’s door to access the lower dash area.
- Locate the knee panel on the left side of the driver's footwell. It may be held in by clips or small screws.
- Carefully pry the panel loose with a flat-head screwdriver or trim tool until it releases from the clips.
- Look for the interior fuse box behind the panel; remove the cover by pulling it straight up or to the side, depending on the model.
- Inspect the fuse diagram on the inside of the cover to locate the circuit you need to check.
- If a fuse is blown, replace it with a new fuse of the same amperage rating and reseat the cover and panel.
When you’re done, snap the knee panel back in place and ensure the cover is secure before testing the circuit.
Replacing a blown fuse and safety tips
If a fuse has blown, use the correct replacement and follow safety precautions to avoid electrical damage or injury. The steps below outline a careful approach.
- Turn off the vehicle and remove the key. Keep the ignition off while working with fuses.
- Check for a blown fuse and remove it using the fuse puller provided in the box, or clean needle-nose pliers.
- Replace with a fuse of the same amperage rating as indicated by the fuse box diagram.
- Inspect the fuse holder and surrounding wiring for signs of damage or corrosion.
- Reinstall the fuse box cover and knee panel, then test the circuit to ensure it works properly.
If the new fuse blows again, the circuit likely has a fault or short. Seek professional help to diagnose wiring or component issues.
Summary
In a 2003 Honda Accord, the interior fuse box is located in the driver’s side knee area under the dash behind a removable panel. Access is gained by removing the knee panel, then using the diagram on the fuse box cover to identify and replace fuses with the correct amperage. Always consult the owner's manual for exact fuse assignments and consider professional assistance if fuses continue to fail.
