The radio fuse in a 2000 Honda Accord is usually in the interior fuse box under the driver’s dash, labeled RADIO, and it’s typically a 10A or 15A fuse. If you don’t find it there, also check the engine compartment fuse box for a separate RADIO or AUDIO fuse. Replacing the fuse with the correct amperage often restores radio power, but persistent blows can indicate a deeper electrical issue.
Understanding where to look for the radio fuse can save time when the radio stops, refuses to turn on, or loses preset memory after restarting the car. This article walks you through where to locate the fuse, how to identify it, and what to do if the fuse continues to blow.
Interior fuse box: primary location and identification
In most 2000 Accords, the main radio fuse sits in the interior fuse box located under the driver’s side dash. The fuse box cover includes a diagram that marks the position and amperage of the RADIO fuse. Access usually requires removing a small panel or knee bolster in the driver's footwell.
How to locate and inspect the interior radio fuse
Follow these steps to locate and inspect the interior radio fuse:
- Park safely and turn off the ignition. Open the driver’s door and locate the lower dash panel on the left side of the steering column.
- Remove the panel or cover to reveal the fuse box. The cover should have a diagram showing each fuse’s function, including the RADIO fuse.
- Find the fuse labeled RADIO (often 10A or 15A). Remove it with a fuse puller or needle-nose pliers.
- Inspect the fuse. A blown fuse typically has a broken filament or a blackened appearance. If blown, replace it with a fuse of the same amperage.
- Reinsert the fuse firmly, reseat the panel, and test the radio by turning the ignition to ON and pressing the radio power button.
Accessing the interior fuse box and replacing the RADIO fuse is a common first step for a dead or resetting radio in this model.
Engine compartment fuse box: when to check it
Some Accord variants route radio power through a fuse in the engine compartment fuse box. If the interior fuse checks out but the radio still won’t power, inspect the engine bay box for a RADIO or AUDIO fuse as well. The exact location can vary, but it’s usually labeled on the underside of the engine bay fuse box cover.
How to check the engine bay radio fuse
Use these steps to inspect a potential engine compartment radio fuse:
- Open the hood and locate the engine compartment fuse/relay box (often near the battery or along the strut tower).
- Consult the fuse box cover for the RADIO or AUDIO circuit. Note the fuse’s amperage, typically 10A or 15A.
- Remove the identified fuse and visually inspect it for a blown filament or discoloration. Replace with the same amperage if blown.
- Reconnect the cover and test the radio. If the fuse repeatedly blows, there may be a short or failing radio component.
Checking both fuse boxes helps rule out where the power to the radio is getting interrupted.
Troubleshooting beyond the fuse
If replacing the RADIO fuse doesn’t restore function, or if the fuse keeps blowing, consider these next steps. They help determine whether the issue is the fuse, wiring, or the radio unit itself.
- Inspect wiring behind the radio for damaged insulation, loose connections, or pinched wires after dash removal.
- Check for a separate RADIO MEMORY fuse that powers clock and preset stations; a failure here can reset memory without fully disabling the radio.
- Test the radio with a multimeter to verify 12-volt power at the radio’s power supply pin and a solid ground.
- If the fuse blows repeatedly even with a confirmed good radio, there may be a short in the harness or a fault within the radio head unit that requires a professional diagnosis.
Persistent fuse blows should prompt professional inspection to avoid wiring damage or electrical hazards.
Summary
For a 2000 Honda Accord, start by checking the interior fuse box under the driver’s dash for a RADIO fuse (commonly 10A or 15A). If the fuse appears intact, also inspect the engine compartment fuse box for a RADIO or AUDIO fuse. Replace any blown fuse with the same amperage and reseat the panel. If issues persist, investigate the radio’s wiring, memory fuse, or seek professional help to diagnose potential shorts or radio unit faults. A systematic check of these fuses usually resolves most power-loss radio problems in this model year.
