Quick answer
The 2019 Honda Civic has two primary fuse box locations:
- Under-Hood Fuse Box: Located in the engine bay on the driver's side, near the battery.
- Interior Fuse Box: Located under the driver's side of the dashboard, near the kick panel.
Always consult the diagram printed on the fuse box lid or in your owner's manual to confirm fuse locations, as they can vary slightly based on your vehicle's trim level and options.
Under-Hood Fuse Box
This fuse box contains high-amperage fuses and relays that protect critical engine and safety components. To access it, open the hood and look for a black plastic box on the driver's side.

Interior Fuse Box
This fuse box is located under the driver's side dashboard, often tucked away above the kick panel. It handles most of the fuses for cabin electronics and accessories.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| 1 | 10A | Red | SRS (Airbag System) |
| 2 | 20A | Yellow | Power Outlet (Front / Cigar Lighter) |

| 10 | 7.5A | Brown | ACC (Accessory) |
| 13 | 10A | Red | Daytime Running Lights |
| 17 | 7.5A | Brown | Park/Tail Lights |
| 23 | 30A | Pink | Front Wipers |
| 28 | 15A | Blue | Radio / Infotainment System |
| 29 | 10A | Red | Door Locks |
| 41 | 7.5A | Brown | Small Lights |
| 42 | 40A | Green | Blower Motor |
How to Test a Fuse
Testing a fuse is a simple process. You can often tell if a fuse is blown just by looking at it.
- Turn off the ignition and the affected component.
- Locate and remove the fuse using the fuse puller tool, which is usually stored in one of the fuse boxes.
- Inspect the fuse. A good fuse will have a continuous, unbroken metal wire running through its plastic body. A blown fuse will have a broken or melted wire.
- For a more accurate test, use a multimeter set to continuity or resistance. Touch the probes to each of the fuse's metal tabs. A good fuse will beep or show near-zero resistance. A blown fuse will show no reading.
- Replace the blown fuse with a new one of the exact same amperage rating. Using a higher-amperage fuse can cause a fire.
Common Blown Fuses on the 2019 Honda Civic
-
Power Outlet / Cigar Lighter (Interior Fuse #2): This is one of the most common fuses to blow, often due to a faulty phone charger or plugging in an accessory that draws too much power. If this fuse blows, first check the device you plugged in and inspect the outlet for any foreign objects like coins.
-
Radio / Infotainment (Interior Fuse #28): If your radio or touchscreen suddenly goes black, this fuse is the first place to look. It can sometimes blow during software updates, after jump-starting the car, or due to an internal fault in the audio unit itself.
-
Fuel Pump (Under-Hood Fuse #16): If your Civic cranks but won't start, a blown fuel pump fuse could be the culprit. If you replace the fuse and it blows again immediately, it suggests a more serious problem with the fuel pump or its wiring that needs professional diagnosis.
If you're uncomfortable diagnosing an electrical issue or if a fuse repeatedly blows, it's best to seek professional help. Find a trusted shop on Repairius.
Before you pull a fuse on the 2019 Honda Civic
- Use the label printed on the panel cover or the owner's manual for your exact build. Layouts change with options, model year and build date, so a chart for another truck can be wrong.
- Replace a blown fuse only with the same amp rating. A larger fuse can let wiring overheat.
- A fuse that blows again right away means a short or failing component downstream. Find the cause before replacing it again.
- A good fuse doesn't prove the circuit works — relays, grounds and connectors fail too.
- Disconnect the battery before working near high-current fuses or cables.
