2023 Subaru Crosstrek Fuse Box Diagram & Amperage

Quick Answer

The 2023 Subaru Crosstrek features three main fuse box locations: under the hood, under the driver's side dashboard, and in the cargo area.

Under-Hood Fuse Box

The under-hood fuse box is located in the engine compartment, typically near the battery on the driver's side. This box houses fuses and relays for critical engine components, headlights, and other high-current systems.

Relays:

• R1: Main Fan Relay
• R2: A/C Clutch Relay
• R3: Fuel Pump Relay
• R4: Starter Relay
• R5: Headlight High Beam Relay
• R6: Headlight Low Beam Relay

Passenger Compartment (Driver's Side Dash) Fuse Box

This fuse box is located under the dashboard on the driver's side, typically behind a removable panel or kick plate. It protects various interior electrical components and accessories.

Relays:

• R1: ACC Relay
• R2: Power Window Relay
• R3: Blower Motor Relay

Cargo Area Fuse Box

For some trims and optional equipment, a supplemental fuse box may be located in the cargo area, often behind a trim panel on the side or under the cargo floor. This box typically handles power for specific features like a rear accessory power outlet, or specific optional equipment.

How to Test a Fuse

Testing a fuse is a straightforward process. You will need a fuse puller (usually found in the fuse box lid or with the vehicle's tool kit) and a multimeter or a fuse tester.

1. Locate the suspected fuse: Refer to the fuse box diagram to identify the fuse for the circuit you are troubleshooting.
2. Turn off the ignition: Ensure the vehicle is off to prevent electrical shock or damage.
3. Remove the fuse: Use the fuse puller to carefully remove the fuse from its slot.
4. Visually inspect the fuse: Look at the metal wire inside the fuse. If it's broken or melted, the fuse is blown. Most modern fuses are clear, making this easy.
5. Use a multimeter (optional but recommended): Set your multimeter to the continuity setting (usually indicated by an audible beep symbol or ohm symbol). Touch the probes to the metal contact points on top of the fuse. If the multimeter beeps or shows a reading close to zero ohms, the fuse is good. If there's no beep or an "OL" (open loop) reading, the fuse is blown.
6. Replace with a new fuse: If the fuse is blown, replace it with a new fuse of the exact same amperage rating and color. Never replace a fuse with one of a higher amperage, as this can cause severe electrical damage or fire.

Common Blown Fuses on this Vehicle

While all fuses can eventually fail, some circuits are more prone to blowing than others due to their frequent use or the components they protect. On the 2023 Subaru Crosstrek, common culprits for blown fuses often include:

• Cigar Lighter/12V Power Outlets: These fuses (often 15A or 20A) frequently blow due to overcurrent from charging multiple devices or using high-power accessories. If your phone charger or air compressor stops working, check these first.
• Blower Motor: If your climate control fan stops working on all speeds, the blower motor fuse (typically 20A or 30A in the under-hood box or passenger compartment box) could be the issue. A failing blower motor can also draw excessive current and blow its fuse.
• Headlights/Tail Lights: A single blown headlight or tail light fuse (10A or 20A in the under-hood box) will only affect one side or type of light (e.g., only low beams on one side). If both headlights or all tail lights go out, there might be a relay issue or a main power fuse. Always check the bulbs first as a simpler fix.

What to check first: Before diving deep into fuse diagnosis, consider the symptoms. Is it a specific accessory, a single light, or a whole system? This can quickly narrow down which fuse box to investigate. Always verify the printed legend on your physical fuse box lid, as configurations can vary slightly due to trim levels and optional equipment.
