2025 Subaru Forester Fuse Box Diagram & Amperage

Quick Answer

The 2025 Subaru Forester features three main fuse box locations: under the hood, behind the driver's side kick panel (dashboard), and in the cargo area.

Under-Hood Fuse Box

The under-hood fuse box typically houses fuses and relays for critical engine components, lighting, and other high-current systems. It's usually located on the passenger side of the engine bay, near the battery.

Relay Locations (Under-Hood):

• Main Relay: Controls power to various engine components.
• Fuel Pump Relay: Activates the fuel pump.
• Starter Relay: Engages the starter motor.
• Cooling Fan Relay: Controls the engine cooling fan.
• A/C Clutch Relay: Engages the air conditioning compressor clutch.
• Horn Relay: Activates the horn.

Passenger Compartment Fuse Box (Driver's Side Kick Panel)

This fuse box is typically located on the driver's side, behind a cover near the kick panel or under the dashboard. It supplies power to various interior electrical components, accessories, and convenience features.

Relay Locations (Passenger Compartment):

• Power Window Relay: Controls power to the power windows.
• Door Lock Relay: Controls power to the central door locking system.
• Wiper Relay: Controls the front windshield wipers.

Cargo Area Fuse Box

Some 2025 Subaru Forester models may feature a fuse box in the cargo area, often located behind a trim panel on one of the side walls or under the cargo floor. This box typically handles power for rear accessories, such as additional 12V outlets, power liftgate (if equipped), and rear heated seats.

Note on Trim Variations: Fuse box configurations can vary slightly between different trim levels and optional equipment of the 2025 Subaru Forester. Always refer to the specific fuse legend printed on the inside of your vehicle's fuse box cover for the most accurate information.

How to Test a Fuse

Testing a fuse is a straightforward process:

1. Locate the fuse box: Refer to the general locations described above and then find the specific fuse box lid.
2. Remove the fuse: Use the plastic fuse puller usually located within the fuse box lid or a pair of small needle-nose pliers.
3. Inspect visually: Look at the metal wire inside the fuse. If the wire is broken or melted, the fuse is blown and needs to be replaced.
4. Use a multimeter (for a more thorough test):
   • Set your multimeter to the continuity setting (usually indicated by an audible beep or a resistance symbol).
   • Touch the probes to the two metal prongs on top of the fuse. If the multimeter beeps or shows a very low resistance reading (close to 0 ohms), the fuse is good. If there's no beep or the reading is "OL" (open loop), the fuse is blown.

Always replace a blown fuse with a new fuse of the exact same amperage rating and type. Using a fuse with a higher amperage can lead to electrical system damage or even fire.

Common Blown Fuses on This Vehicle

While the 2025 Subaru Forester is a new model, based on previous generations and common automotive issues, some fuses are more prone to blowing due to their circuit demands:

• Cigar Lighter / 12V Power Outlets (F4 in Passenger Compartment Fuse Box): These fuses commonly blow due to overcurrent from charging multiple devices or using high-power accessories. If your 12V outlets aren't working, check this fuse first, and ensure any devices you're plugging in are within the circuit's limits.
• Blower Motor Fuse (F16 in Under-Hood Fuse Box): The blower motor draws significant current, especially on higher fan settings. A failing blower motor or a blockage in the ventilation system can cause this fuse to blow. If your A/C or heat fan isn't working, check this fuse.
• Headlight Fuses (F1-F4 in Under-Hood Fuse Box): While not as common as accessory fuses, a short circuit in a headlight assembly or a faulty bulb can lead to a headlight fuse blowing. If one of your headlights is out, and the bulb is confirmed good, check the corresponding fuse.
• Radio/Infotainment Fuse (F1 in Passenger Compartment Fuse Box): Issues with aftermarket installations, wiring defects, or internal faults in the radio itself can sometimes cause this fuse to blow, leading to a non-functional infotainment system.

When troubleshooting a blown fuse, always consider what components stopped working at the same time and inspect for any visible damage to wiring or connectors related to that circuit. Do not repeatedly replace a fuse that blows immediately, as this indicates a persistent short circuit that needs professional diagnosis.
