2015 Honda CR-V – Fuse Box Diagram & Amperage

Quick answer

The 2015 Honda CR-V features two main fuse box locations: under the hood (engine compartment) and under the dashboard (driver's side kick panel).

Under-Hood Fuse Box (Engine Compartment)

This fuse box is located in the engine compartment, typically near the battery. It houses fuses for major components and relays. Always refer to the diagram on the fuse box lid for the exact layout for your specific trim.

Relay Locations (Under-Hood):

The under-hood fuse box also houses several relays essential for various systems. Common relays include:

• Starter Relay: Engages the starter motor.
• Fuel Pump Relay: Powers the fuel pump.
• A/C Compressor Clutch Relay: Activates the A/C compressor.
• Headlight Relays: Control power to the headlights.
• Cooling Fan Relays: Operate the radiator cooling fans.

Under-Dash Fuse Box (Driver's Side)

This fuse box is located on the driver's side, typically behind a removable panel in the kick panel area. It protects many of the interior electrical components.

Relays (Under-Dash):

While most of the under-dash components are managed by fuses, some systems may have integrated relays within control modules, or small dedicated relays for specific functions like power windows or door locks. These are generally less accessible than the under-hood relays.

How to Test a Fuse

Testing a fuse is a straightforward process:

1. Safety First: Always turn off the ignition and any affected electrical components before attempting to test or replace a fuse.
2. Locate: Find the suspected fuse in the appropriate fuse box using the diagrams provided in this article or, more accurately, the diagram on your car's fuse box lid.
3. Inspect Visually: Many fuses have a clear plastic body. Look for a broken or burnt wire inside the fuse. If it's broken, the fuse is blown and needs replacement.
4. Use a Multimeter (Recommended):
   • Set your multimeter to the continuity setting (usually indicated by a speaker icon). If it doesn't have continuity, set it to measure ohms (Ω).
   • Touch the probes to the two metal test points on top of the fuse. Do not remove the fuse for this test if possible, as it verifies flow through the fuse in the circuit.
   • If the multimeter beeps (continuity) or shows a reading close to zero ohms, the fuse is good.
   • If there's no beep or no reading (open circuit/infinite ohms), the fuse is blown.
5. Use a Test Light:
   • Connect the alligator clip of the test light to a good ground point on the vehicle's metal frame.
   • With the ignition on (or the circuit powered), touch the probe of the test light to each metal test point on top of the fuse. (Again, do not remove the fuse if possible).
   • If the test light illuminates on both sides of the fuse, the fuse is good.
   • If it illuminates on one side but not the other, the fuse is blown.

Common Blown Fuses on This Vehicle

While any fuse can blow, some are more prone to failure due to their circuit demands or common user habits:

• Cigar Lighter / 12V Power Outlet Fuses (Cargo and Console): These often blow due to short circuits from faulty charging devices, inserting foreign objects, or overloading with high-draw accessories. If your phone charger or portable air pump stops working, check these first.
• Radio / Infotainment System Fuse: Issues with aftermarket head units, sudden power surges, or internal component failures can cause this fuse to blow, leading to a loss of radio function.
• Blower Motor Fuse: A failing blower motor, a clogged cabin air filter causing the motor to work harder, or an electrical short in the blower motor circuit can cause this fuse to blow, resulting in no air from the vents.
• Headlight Fuses: While less common on modern vehicles, a short in the headlight wiring or a faulty bulb can occasionally cause a headlight fuse to blow. If one headlight is out, it's worth checking its specific fuse.
• Trailer Brake Fuse: If your CR-V is equipped with a trailer hitch and wiring, issues with trailer wiring, short circuits on the trailer, or incorrect wiring can frequently blow this fuse if present.

When a fuse blows, always investigate why it blew. Simply replacing a fuse without addressing the underlying problem will likely result in the new fuse blowing again.
