Quick Answer
The 2025 Subaru Crosstrek features three primary fuse box locations:
- Under-hood Fuse Box: Located in the engine compartment, typically on the passenger side.
- Cabin Fuse Box (Driver's Side Dash): Situated behind a kick-panel on the driver's side of the dashboard.
- Cargo Area Fuse Box: Found in the cargo area, often on a side panel.
Under-hood Fuse Box
The under-hood fuse box contains fuses and relays for critical engine components, lighting, and other high-current systems. Always refer to the fuse diagram on the inside of the fuse box cover for the most accurate information for your specific vehicle trim.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| 1 | 15A | Blue | Engine Control Module (ECM) / Powertrain Control Module (PCM) |
| 2 | 20A | Yellow | Fuel Pump |
| 3 | 10A | Red | Ignition System |
| 4 | 30A | Green | Starter Relay |
| 5 | 25A | Clear | Headlights (Low Beam, Left) |
| 6 | 25A | Clear | Headlights (Low Beam, Right) |
| 7 | 20A | Yellow | Headlights (High Beam, Left) |
| 8 | 20A | Yellow | Headlights (High Beam, Right) |
| 9 | 15A | Blue | A/C Clutch |
| 10 | 40A | Green | Blower Motor (Main) |
| 11 | 30A | Green | ABS Control Unit |
| 12 | 10A | Red | Horn |
| 13 | 15A | Blue | Cooling Fans |
| 14 | 10A | Red | O2 Sensors |
| 15 | 15A | Blue | Transmission Control Unit (TCU) |
Relay Locations (Under-hood):
- Starter Relay: Typically located near the starter fuse.
- Fuel Pump Relay: Often next to the fuel pump fuse.
- Cooling Fan Relays: Usually two relays, one for each fan speed or fan.
- Horn Relay: Powers the vehicle's horn.
- A/C Compressor Relay: Engages the air conditioning compressor clutch.
Cabin Fuse Box (Driver's Side Dash)
This fuse box manages electrical components within the cabin, including interior lighting, infotainment, and convenience features. Always verify the fuse panel cover for the precise layout of your 2025 Crosstrek.

| 1 | 10A | Red | Radio / Infotainment System |
| 2 | 15A | Blue | 12V Power Outlet (Front/Console) |
| 3 | 7.5A | Brown | Airbag System (SRS) |
| 4 | 10A | Red | Brake Lights |
| 5 | 20A | Yellow | Blower Motor (Cabin Fan) |
| 6 | 10A | Red | Tail Lights / Parking Lights |
| 7 | 7.5A | Brown | Instrument Cluster |
| 8 | 10A | Red | Power Windows (Driver's Side) |
| 9 | 10A | Red | Power Windows (Passenger's Side) |
| 10 | 10A | Red | Door Locks |

| 15 | 15A | Blue | Heated Seats (Driver) |
| 16 | 15A | Blue | Heated Seats (Passenger) |
Cargo Area Fuse Box
For features located in or serving the cargo area, such as additional power outlets or specific accessories, you'll find a fuse box here. Remember to always consult the fuse diagram printed on the cover.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| 1 | 20A | Yellow | 12V Power Outlet (Cargo Area) |
| 2 | 15A | Blue | Rear Wiper |
| 3 | 10A | Red | Trailer Brake Controller (Accessory) |
| 4 | 7.5A | Brown | Rear Defroster Relay Control |
| 5 | 10A | Red | Liftgate Release |
How to Test a Fuse
Testing a fuse is a straightforward process:
- Locate the Fuse Box: Identify the correct fuse box for the circuit you're troubleshooting.
- Identify the Suspect Fuse: Refer to your vehicle's fuse diagram (usually on the inside of the fuse box cover) to find the fuse associated with the malfunctioning component.
- Visual Inspection: Most modern blade-type fuses have a small wire visible through their clear plastic body. If this wire is broken or melted, the fuse is blown and needs replacement.
- Use a Multimeter or Test Light: For a more accurate test, remove the fuse and use a multimeter set to continuity mode. Touch the probes to the metal contact points on the top of the fuse. A good fuse will show continuity. A test light can also be used; if it lights up when touching both test points on the fuse (with the fuse installed and ignition on), the fuse is good. If it only lights up on one side, the fuse is blown.
- Replace with Correct Amperage: Always replace a blown fuse with a new one of the exact same amperage rating and type. Using a fuse with a higher amperage can lead to electrical system damage or fire.
Common Blown Fuses on this Vehicle
While any fuse can blow, some are more commonly encountered due to high usage or specific component issues:
- Cigar Lighter / 12V Power Outlet Fuses: These often blow due to overcurrent from charging multiple devices or using high-power accessories. If your 12V outlets aren't working, check these first.
- Brake Light Fuses: A blown brake light fuse (often labelled as "STOP" or "BRAKE") can be caused by a faulty brake light switch or issues with aftermarket trailer wiring.
- Radio / Infotainment Fuses: If your radio or display goes blank, start by checking its dedicated fuse. Sometimes old CDs getting stuck or a momentary power surge can cause these to blow.
- Headlight Fuses: A single headlight out could be a blown bulb, but if both are out, or if only one beam isn't working, a fuse or relay could be the culprit. Check the individual high beam and low beam fuses.
Always check the easiest fix first. Before diving deep into electrical diagnosis, quickly verify the relevant fuse. Many issues can be resolved with a simple fuse replacement.

Before you pull a fuse on the 2025 Subaru Crosstrek
- 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.
