<H2>Quick answer</H2>
<p>Your 2015 Honda Civic has two main fuse box locations:</p>
<ul>
<li><strong>Under-hood Fuse Box:</strong> Located in the engine compartment, typically near the battery on the driver's side.</li>
<li><strong>Interior Fuse Box:</strong> Found in the passenger compartment, behind a panel on the driver's side kick panel.</li>
</ul>
<H2>Under-hood Fuse Box</H2>
<p>The under-hood fuse box contains fuses for critical engine components, headlights, and high-current accessories. The lid usually has a diagram. Always verify with your vehicle's specific diagram.</p>

<H3>Under-hood Relay Locations</H3>
<p>In addition to fuses, the under-hood fuse box also houses several important relays:</p>
<ul>
<li><strong>Starter Relay:</strong> Engages the starter motor when you turn the key.</li>
<li><strong>Fuel Pump Relay:</strong> Powers the fuel pump.</li>
<li><strong>Main Relay:</strong> Supplies power to the ECM/PCM and other critical engine components.</li>
<li><strong>Headlight Relays:</strong> Control power to your headlights (often separate for high and low beams).</li>
<li><strong>Fan Relays:</strong> Operate the radiator and A/C condenser fans.</li>
<li><strong>A/C Clutch Relay:</strong> Engages the air conditioning compressor clutch.</li>
</ul>
<H2>Interior Fuse Box (Driver's Side Kick Panel)</H2>
<p>The interior fuse box primarily handles fuses for cabin accessories, power windows, radio, and other comfort features. This box is located behind a small access panel on the driver's side, near the kick panel by your left foot. Again, consult your Civic's owner's manual or the diagram on the fuse box cover for the exact layout.</p>

<H3>Interior Relay Locations</H3>
<p>While the interior fuse box is primarily fuses, you may find relays for certain cabin functions such as:</p>
<ul>
<li><strong>Power Window Relay:</strong> Controls power to the power window motors.</li>
<li><strong>Accessory Relay:</strong> Powers general accessories when the ignition is on.</li>
<li><strong>Blower Motor Relay:</strong> Controls the blower motor for the HVAC system.</li>
</ul>
<H2>How to test a fuse</H2>
<ol>
<li><strong>Locate the fuse box:</strong> Refer to the "Quick Answer" section for locations.</li>
<li><strong>Identify the suspect fuse:</strong> Use the diagrams provided (and your vehicle's specific lid diagram) to find the fuse for the malfunctioning component.</li>
<li><strong>Visually inspect:</strong> Many fuses have a visible wire inside. If this wire is broken or melted, the fuse is blown.</li>
<li><strong>Use a fuse tester or multimeter:</strong>
<ul>
<li><strong>Fuse Tester:</strong> These inexpensive tools light up if a fuse is good. Touch the probes to the small metal test points on the top of the fuse.</li>
<li><strong>Multimeter:</strong> Set your multimeter to continuity mode (looks like a speaker icon). Touch the probes to the metal test points. A working fuse will show continuity (the multimeter will beep or show a reading close to zero ohms). No continuity means the fuse is blown.</li>
</ul>
</li>
<li><strong>Replace with the correct rating:</strong> ALWAYS replace a blown fuse with a new fuse of the exact same amperage rating (e.g., replace a 10A fuse with a 10A fuse). Using a higher-rated fuse can cause serious electrical damage or fire.</li>
</ol>
<H2>Common blown fuses on this vehicle</H2>
<p>While any fuse can blow, some are more commonly affected due to their function or the loads they handle. If you're experiencing an issue, check these first:</p>
<ul>
<li><strong>Cigar Lighter / 12V Power Outlet:</strong> These often blow due to over-current from charging multiple devices or using high-power accessories.</li>
<li><strong>Radio / Infotainment System:</strong> A short in an aftermarket accessory or a fault within the head unit can sometimes cause this fuse to blow.</li>
<li><strong>Brake Lights:</strong> A stuck brake light switch or a short in the wiring can cause this fuse to pop.</li>
<li><strong>Headlights:</strong> While less common for modern vehicles, a short in the wiring or a faulty bulb (especially if it's an aftermarket HID/LED conversion) could occasionally blow a headlight fuse.</li>
<li><strong>Blower Motor:</strong> A struggling blower motor due to debris, a worn motor, or a bad resistor can draw too much current and blow its fuse.</li>
</ul>
<p><strong>Always remember:</strong> A blown fuse is often a symptom of an underlying problem. If a new fuse blows immediately or repeatedly, there's a fault in the circuit that needs to be diagnosed and repaired.</p>

Before you pull a fuse on the 2015 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.
Don't overhaul your shop. Test Repairius on your next job.
