2017 Subaru Crosstrek Fuse Box Diagram & Amperage

Quick Answer

The 2017 Subaru Crosstrek has two primary fuse box locations:

• Under-hood Fuse Box: Located in the engine compartment, typically on the driver's side near the battery.
• Passenger Compartment Fuse Box: Found behind a cover on the lower driver's side dash, sometimes requiring removal of a kick panel.

Under-hood Fuse Box

This fuse box contains fuses and relays for major systems like the engine control, cooling fan, headlights, and ABS. Always consult the diagram on the fuse box lid for the most accurate information for your specific vehicle trim.

Relays in Under-hood Fuse Box:

• R1: Cooling Fan Relay 1
• R2: Cooling Fan Relay 2
• R3: ABS Motor Relay
• R4: Starter Relay
• R5: Fuel Pump Relay
• R6: A/C Compressor Clutch Relay
• R7: Horn Relay
• R8: Headlight Low Beam Relay
• R9: Headlight High Beam Relay

Passenger Compartment Fuse Box

Located on the driver's side, typically behind a small access panel near the driver's left foot or knee. This box manages fuses for interior accessories, power windows, radio, and lighting.

Relays in Passenger Compartment Fuse Box:

• R1: Power Window Relay
• R2: Door Lock Relay
• R3: Accessory Relay

How to Test a Fuse

Testing a fuse is a simple process that can save you a trip to the mechanic. Here's how to do it:

1. Locate the Fuse Box: Refer to your owner's manual or the Quick Answer section above to find the correct fuse box.
2. Identify the Suspect Fuse: Look at the fuse box diagram (usually on the lid or in the owner's manual) to find the fuse for the component that isn't working.
3. Inspect Visually: Many fuses have a small wire inside. If this wire is broken or melted, the fuse is blown. However, some fuses (especially the larger cartridge-style ones) can blow without visible signs.
4. Use a Fuse Tester or Multimeter:
   • Fuse Tester: These inexpensive tools light up to indicate a good fuse. Touch the tester's probe to the two small metal test points on top of the fuse. If both sides light up, the fuse is good. If only one side (or neither) lights up, the fuse is blown.
   • Multimeter: Set your multimeter to the continuity setting (often indicated by a speaker icon). Touch the probes to the test points on the fuse. A good fuse will show a reading close to zero ohms or emit a beep, indicating continuity. A blown fuse will show an open circuit (OL) or no beep.
5. Replace (If Blown): If the fuse is blown, replace it with a new fuse of the exact same amperage rating and type. Using a fuse with a higher amperage can cause severe electrical damage or even a fire.

Common Blown Fuses on This Vehicle

While any fuse can blow, some are more commonly encountered by 2017 Subaru Crosstrek owners due to various factors. If you're experiencing an issue, check these first:

• Cigar Lighter/12V Outlet Fuses (Passenger Compartment F4 & optionally F13): These are frequently blown when charging incompatible devices, inserting foreign objects, or if there's a short in the accessory being used. If your phone charger suddenly stops working, this is your first stop.
• Radio/Infotainment Fuse (Passenger Compartment F2): Issues with aftermarket installations, static electricity, or even a sudden power surge can sometimes cause this fuse to blow, leading to a blank screen or no audio.
• Blower Motor Fuse (Under-hood F18 or Passenger Compartment F1): If your fan for the heating or AC stops working entirely, this fuse is a common culprit. A failing blower motor itself can draw too much current and cause the fuse to blow.
• Headlight Fuses (Under-hood F11, F12, F13, F14): While less common, a short in a headlight bulb or wiring can blow these fuses. If one or both headlights suddenly go out, check here first.
• Stop/Brake Light Fuse (Under-hood F19): If your brake lights aren't working, this is the most likely cause. Sometimes a faulty brake pedal switch or a short in the trailer wiring (if applicable) can lead to this fuse blowing.

Remember, if a fuse blows repeatedly, there's an underlying problem that needs to be addressed, such as a short circuit or a faulty component drawing excessive current. Consult a trusted mechanic if you encounter recurring fuse issues.
