Honda Fit Fuse Box: Location & Guide
TL;DR
Honda Fit has an under-hood fuse/relay box (engine bay, by the battery) and an interior fuse box (driver's side, under the dash near the door); both open via clip-on covers, and the lid diagram plus owner's manual are the authoritative fuse map.
Where the Honda Fit fuse boxes are located
Every Honda Fit generation sold in North America (and the Brazilian/Latin American market Fit) uses the same basic two-box layout. The under-hood fuse/relay box sits in the engine compartment, usually near the battery or along the front of the firewall, and handles higher-current circuits like the cooling fan, starter, and main power feeds. The interior (passenger compartment) fuse box is located under the dashboard on the driver's side, near the far end by the door or kick panel, and covers cabin circuits such as lights, power windows, and accessories.
How to open each box
The under-hood cover is plastic and either lifts straight off or releases with one or two side clips - no tools are normally required. The interior box is hidden behind a small trim panel that pulls straight out or swings down once you release its retaining tabs; some model years have a tiny recess to get a fingernail or flat tool started. Never force a cover - if it resists, look for an additional clip you may have missed.
Finding the exact fuse legend
Because exact fuse positions and amperage assignments can shift between model years and trims even within the same generation, the reliable source is the fuse map printed on the inside of the box lid itself, plus the electrical/fuses chapter of your owner's manual. Always match the diagram to your specific car rather than relying on a generic online list.
Commonly blown fuses and their symptoms
- Cigarette lighter / 12V accessory outlet fuse: when blown, the outlet stops charging phones or powering accessories while everything else works fine - a very common one because of phone chargers and aftermarket gadgets left plugged in.
- Radio / infotainment fuse: a blown fuse here kills the screen, sound system, and sometimes the clock, while climate and lights keep working normally.
- Interior lights fuse: dome light, map lights, and sometimes glovebox or trunk light go dark together.
- Blower motor fuse: the HVAC fan stops moving air at any speed, though the AC compressor and heater core are otherwise fine.
- Fuel pump relay/fuse: the engine cranks but won't start or stalls immediately, since the pump can't build fuel pressure - this one is safety-relevant and worth diagnosing carefully.
Checking and replacing a fuse safely
With the ignition off, pull the suspect fuse using the small plastic puller clipped inside the box lid. Hold it up to light: a blown fuse shows a broken or melted metal strip inside the plastic body. For certainty, a test light or multimeter across the fuse terminals with the circuit powered confirms continuity. Always replace with the same amperage rating (color and number printed on top) - never a higher-rated fuse, which removes the protection the circuit was designed around and can lead to melted wiring or fire risk.
When a fuse keeps blowing
If a fresh, correctly-rated fuse blows again quickly, that circuit almost always has a short or an overloaded component drawing excess current, not a coincidence of bad luck. Repeated blowing is a sign to stop swapping fuses and instead have the circuit diagnosed; pulling stored diagnostic trouble codes from the vehicle's computer can point straight to the affected module or wiring section and save hours of guesswork.

Frequently asked questions
Where is the fuse box on a Honda Fit?
Every Honda Fit generation has two fuse boxes: an under-hood fuse/relay box in the engine bay near the battery, and an interior fuse box under the dashboard on the driver's side near the door or kick panel. The under-hood cover lifts off or unclips, and the interior cover is a small trim panel that pulls or swings out.
Why does my Honda Fit's cigarette lighter or 12V outlet not work?
The most common cause is a blown fuse dedicated to that outlet - it fails independently of the rest of the electrical system, often from a phone charger or accessory drawing too much current or from a short in the plug. Check the fuse legend on the box lid to find the correct fuse, then inspect it for a broken filament and replace with the same amperage if blown.
How do I know if a fuse is blown on my Honda Fit?
Pull the fuse with the small plastic puller clipped inside the fuse box lid and hold it to light - a blown fuse shows a visibly broken or melted metal strip inside the clear plastic housing. For a definitive check, use a test light or multimeter across the fuse terminals with the ignition on to confirm there's no continuity.
What does it mean if a fuse keeps blowing repeatedly on my Fit?
A fuse that blows again shortly after being replaced with the correct amperage almost always indicates a short circuit or an overloaded component on that circuit, not bad luck. Continuing to replace fuses without diagnosing the cause risks wiring damage; pulling stored fault codes from the car's computer helps pinpoint which circuit or module is at fault before further repair.
