Quick answer
Your 2019 Subaru Crosstrek has two main fuse box locations:
- Under the hood: In the engine bay, on the driver's side near the battery.
- In the cabin: Under the dashboard, on the driver's side, to the left of the steering column.
Under-Hood Fuse Box
The under-hood fuse box contains higher-amperage fuses and relays that control major systems like the engine, cooling fans, and headlights. To access it, open the hood and locate the black plastic box on the driver's side of the engine compartment.
Here are the most common fuses and relays you'll find in this location. Note that your Crosstrek's specific layout may vary slightly depending on trim level and options. Always check the diagram printed on the inside of the fuse box lid to confirm fuse locations and ratings.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| 1 | 30A | Pink | Main Fan Motor |
| 2 | 30A | Pink | Main Fan Motor |
| 3 | 20A | Yellow | Fuel Pump |
| 4 | 20A | Yellow | Main IG |
| 5 | 15A | Blue | Horn |
| 6 | 15A | Blue | Headlight (High Beam, Right) |
| 7 | 15A | Blue | Headlight (High Beam, Left) |
| 8 | 15A | Blue | A/C Compressor Clutch |
| 9 | 10A | Red | ABS Module |
| 10 | 10A | Red | ECM/PCM |
| 11 | 7.5A | Brown | Starter Relay |
| 12 | 7.5A | Brown | Ignition |
Relay Locations (Under-Hood)
- R1: Starter Relay
- R2: Main Fan Relay
- R3: Fuel Pump Relay
- R4: A/C Compressor Clutch Relay
In-Cabin Fuse Box
The in-cabin fuse box is located under the dashboard on the driver's side. You may need to remove a small plastic trim panel to access it. This fuse box handles most of the interior and accessory circuits.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| 5 | 20A | Yellow | Power Outlet (Cargo Area) |
| 6 | 20A | Yellow | Power Outlet (Center Console) |
| 7 | 15A | Blue | Radio / Infotainment System |
| 11 | 15A | Blue | Blower Motor |
| 13 | 10A | Red | Tail/Parking Lights |
| 14 | 10A | Red | Brake Lights |
| 15 | 10A | Red | Airbag System |
| 17 | 7.5A | Brown | Interior Lights |
| 18 | 7.5A | Brown | Power Mirrors |
| 20 | 7.5A | Brown | Heated Seats |
| 21 | 7.5A | Brown | Sunroof |
How to test a fuse
Testing a fuse is a simple process. You can often tell if a fuse is blown just by looking at it. Inside the plastic body of the fuse is a small metal filament. If that filament is broken, the fuse is blown and needs to be replaced.
For a more accurate test, you can use a multimeter. Set the multimeter to the continuity setting (it often looks like a sound wave symbol). Touch the two probes of the multimeter to the two metal tabs on the top of the fuse. If the multimeter beeps, the fuse is good. If it doesn't beep, the fuse is blown.
Common blown fuses on this vehicle
- Power Outlet (Cigar Lighter) Fuses: These are some of the most common fuses to blow. The first thing to check is the device you plugged in. Often, a faulty phone charger or other accessory is the culprit. Also, check the outlet itself for any foreign objects that could be causing a short.
- Radio/Infotainment Fuse: If your radio or touchscreen is dead, this fuse is the first place to look. If the fuse is blown, it could be a sign of an internal fault in the head unit, but it's more likely a simple power surge. Replace the fuse and see if the problem is resolved.
- Headlight Fuses: If one of your headlights is out, it's more likely a burned-out bulb than a blown fuse. However, if a headlight fuse does blow, it could indicate a problem with the wiring or the headlight assembly itself.

Before you pull a fuse on the 2019 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.
