Where are the fuses in a 2018 Honda Civic?
In the 2018 Honda Civic, fuses are housed in two main locations: an interior fuse box inside the cabin on the driver’s side, and an engine-compartment fuse box in the engine bay. The layout and exact fuse assignments are shown on the lids of each box and in the owner's manual. This guide provides the locations, access steps, and what those fuses typically protect.
Interior fuse box
The interior fuse box is located on the driver's side of the cabin, beneath the dash area. Access is usually gained by removing a small panel or cover in the lower dash/kick panel area near the door. The lid of the box carries a diagram that maps each fuse to its circuit.
- Circuits for interior electronics such as the radio/infotainment system
- Climate control and blower motor circuits
- Power windows, door locks, and mirrors
- Instrument cluster and dashboard lighting
- Interior courtesy lights and auxiliary power outlets
The exact fuse numbers and amperages vary by trim level, so the diagram on the fuse box lid should be consulted for your specific Civic. If a fuse blows, replace it with a fuse of the same amperage and inspect the circuit for a short or overload.
Engine compartment fuse box
The engine-compartment fuse box is located in the engine bay, typically on the driver’s side near the front of the vehicle and adjacent to the battery area. The cover bears a diagram detailing the individual fuses and relays contained inside.
- Powertrain control module (engine computer) circuits
- Ignition system and coil/spark-related fuses
- Fuel system fuses (pump and injectors)
- Charging and alternator-related fuses
- Headlights, horn, and signaling circuits
- ABS/VSA and other braking-related fuse circuits
As with the interior box, the exact layout and amperages depend on trim and market, so refer to the engine bay cover diagram for precise details. Use the same amperage as the original fuse when replacing, and investigate any persistent fuse blowage for a potential electrical fault.
Safety and general tips
Before handling fuses, ensure the ignition is off and the key is removed. Use the correct fused rating and avoid metal tools that could ground or short the circuit. If a fuse repeatedly blows, there may be a short or an overloaded component in that circuit; have the vehicle inspected by a qualified technician.
Summary
The 2018 Honda Civic houses fuses in two places: an interior cabin fuse box on the driver's side under-dash and an engine-compartment fuse box in the engine bay. Each box includes a lid diagram showing circuit allocations and amperages. Replacing a fuse with the correct rating and checking for shorts helps maintain electrical safety and reliability.
