Two fuse boxes. One is located in the engine compartment and the other inside the cabin. This setup is standard on most 2003 Honda Accord models, though regional and trim variations can occur.
Fuses protect electrical circuits in a vehicle. For the 2003 Accord, the two main fuse boxes cover engine management, lighting, and interior electronics. The under-hood box houses fuses and relays for critical systems, while the interior box handles fuses for features like the radio, power windows, HVAC, and interior lighting. Always refer to the owner’s manual diagram for the exact fuse labeling and locations.
Locations and what they cover
The two standard fuse boxes and their general purposes are described below.
- Engine compartment fuse/relay box: Located in the engine bay, typically on the side toward the passenger side or near the strut tower. It contains fuses and relays for major systems such as the ECU, fuel pump, ignition, headlights, and emissions-related components.
- Interior fuse box: Located inside the vehicle, usually on the driver's side under the dash or behind a panel on the left kick panel. It contains fuses for interior electronics including the radio, power windows, HVAC controls, lights, and horn.
Knowing the two main fuse blocks helps with diagnosing blown fuses and planning electrical work on the 2003 Accord.
Regional variations and model differences
While two fuse boxes are standard for most North American 2003 Accord models, some markets or trims may have slight variations in labeling or additional fuses for optional equipment. Always consult the specific vehicle’s owner’s manual or the fuse block cover labeling for your exact configuration.
Summary
In a typical 2003 Honda Accord, there are two primary fuse boxes: one in the engine compartment and one inside the cabin. This arrangement covers the car’s essential electrical systems and interior electronics. If in doubt, check the fuse box covers and the owner’s manual for exact locations and fuse ratings.
