Quick Answer
Your 2015 Subaru Crosstrek has two main fuse boxes:
- Interior Fuse Box: Located in the passenger compartment, under the driver's side dashboard.
- Engine Compartment Fuse Box: Found on the driver's side of the engine bay, near the battery.
Below, you'll find detailed diagrams and circuit information for both.
Interior Fuse Box
This fuse box is located under the driver's side of the dashboard, behind a small access panel. You may need to remove a plastic trim piece to access it. This panel primarily houses fuses for interior components like the radio, power outlets, and lighting.

|---|---|---|---|
| 1 | 15A | Blue | Fuel pump |
| 2 | 15A | Blue | All-Wheel Drive (AWD) control module |
| 3 | 7.5A | Brown | Starter signal |
| 4 | 10A | Red | Stop lights |
| 5 | 15A | Blue | Power windows |
| 6 | 15A | Blue | Sunroof |
| 7 | 10A | Red | Air conditioning |
| 8 | 15A | Blue | Seat heaters |
| 9 | 10A | Red | Turn signals |

| 23 | 7.5A | Brown | Power mirrors |
| 24 | 15A | Blue | Door locks |
| 25 | 7.5A | Brown | Accessory power |
Engine Compartment Fuse Box
This fuse box is located on the driver's side of the engine bay, near the battery. It contains higher-amperage fuses and relays that protect critical engine components.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| 1 | 30A | Pink | Radiator fan |
| 2 | 30A | Pink | Main fan |
| 3 | 20A | Yellow | Engine control module (ECM) |
| 4 | 15A | Blue | Ignition coil |
| 5 | 15A | Blue | Fuel injectors |
| 6 | 15A | Blue | Headlight (right) |
| 7 | 15A | Blue | Headlight (left) |
| 8 | 10A | Red | Horn |
| 9 | 10A | Red | Hazard lights |
| 10 | 30A | Pink | ABS |
| 11 | 20A | Yellow | Fog lights |
| 12 | 15A | Blue | A/C compressor |
| 13 | 15A | Blue | Tail lights |
| 14 | 15A | Blue | Park lights |
| 15 | 15A | Blue | Front wiper de-icer |
| 16 | 30A | Pink | Main power |
Relays
The engine compartment fuse box also houses several important relays:
- Starter Relay: Energizes the starter motor.
- Fuel Pump Relay: Controls power to the fuel pump.
- Main Relay: Provides power to the ECM and other engine systems.
- A/C Relay: Engages the A/C compressor clutch.
- Radiator Fan Relay: Controls the operation of the radiator cooling fan.
Note: Fuse and relay configurations can vary slightly depending on your vehicle's trim level and options. Always refer to the diagram on the inside of the fuse box cover to confirm fuse locations and ratings.
How to Test a Fuse
A blown fuse is a common and easy-to-fix problem. Here's how to test a fuse:
- Turn off the ignition and all electrical accessories.
- Locate the suspect fuse using the diagrams above.
- Remove the fuse from the fuse box. A small fuse puller tool is often included in the fuse box.
- Visually inspect the fuse. A good fuse will have a continuous, unbroken metal strip inside. A blown fuse will have a broken or melted strip.
- Use a multimeter or test light (optional). For a more definitive test, you can check for continuity across the two prongs of the fuse with a multimeter. A good fuse will show continuity, while a blown fuse will not.
If you find a blown fuse, replace it with a new fuse of the same amperage rating. Using a fuse with a higher rating can cause damage to the electrical system.
Common Blown Fuses on the 2015 Subaru Crosstrek
- Power Outlet/Cigar Lighter Fuses (Interior, Fuses 12 & 20): These are some of the most common fuses to blow, often due to a faulty phone charger or other accessory plugged into the outlet. If you find a blown fuse, check the device you were using for any signs of damage before replacing the fuse.
- Radio/Audio Fuse (Interior, Fuse 13): If your radio suddenly stops working, this fuse is the first thing to check. It can sometimes blow if there's an issue with the head unit or an aftermarket amplifier.
- Headlight Fuses (Engine Compartment, Fuses 6 & 7): If one of your headlights goes out, it could be a blown fuse, although it's more likely a burned-out bulb. If the bulb is good, check the fuse next. If the fuse is blown, it could indicate a wiring issue.
If a fuse blows repeatedly, it's a sign of a deeper electrical problem that needs to be diagnosed and repaired by a qualified technician.

Before you pull a fuse on the 2015 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.
