Where is the flasher relay on a Subaru Outback?

The flasher relay is typically found in the interior fuse/relay box under the driver’s side dash, though newer Outbacks often rely on an electronic flasher controlled by the Body Control Module rather than a separate relay.

Understanding the flasher relay and why its location matters

The turn signals and hazard lights rely on the flasher system to blink. Depending on the model year, Subaru either uses a traditional, replaceable relay or an electronic control module that performs the same function. Knowing where to look helps you diagnose issues quickly if your signals won’t blink or hazards won’t engage.

Where to look for the flasher relay by generation

The following locations cover the most common setups across Subaru Outback generations. Use the fuse box diagrams on the box covers to confirm the exact relay designation in your car.

• Pre-2010 and early-2010s Outbacks: interior fuse/relay box located under the driver's-side dash. Look for a relay labeled Turn, Flasher, or FL.


• Mid-2010s models (approximately 2011–2016): interior box remains a likely spot; some vehicles also have a secondary relay box in the engine bay with a similar label.


• 2018–present models: the flasher function is often managed by the Body Control Module (BCM) and may not be a separate, replaceable relay; if a dedicated relay is present, it will be in the interior fuse/relay box or engine bay box with a label such as Turn/Flasher.

Conclusion: begin with the under-dash fuse/relay box on the driver's side, verify the diagram, and if you can't find a dedicated flasher relay, consult the owner's manual or a Subaru dealer for the exact BCM-based configuration for your year.

How to test or replace the flasher relay

Follow these steps to diagnose or replace the relay if your signals or hazards misbehave.

• Locate the appropriate fuse/relay box (under-dash driver’s side or engine bay).


• Identify the relay labeled Turn, Flasher, or similar. If none, your model may use a BCM-based system.


• With the ignition off, gently swap the suspected relay with a known-good identical relay from the same box (same amperage rating) and test the signals.


• If hazards work but turn signals do not, the issue could be the turn-signal stalk switch, wiring, or BCM rather than the relay.


• If you cannot locate a replaceable relay or the symptoms persist, contact a certified Subaru technician for a BCM-related diagnosis.

Note: When swapping relays, ensure you use the same amp rating and pin configuration to avoid electrical damage.

Summary

For many Subaru Outback models, the flasher relay sits in the interior fuse/relay box under the driver’s dash, but newer models may rely on a BCM-based electronic flasher with no replaceable relay. Always verify the fuse box diagram for your year, and consult the manual or a technician if you’re uncertain. A precise diagnosis may require checking the stalk switch, wiring, and BCM as well as the relay itself.

Where is the turn signal flasher relay located?

The turn signal relay is most often found in a fuse box, which is usually located in the driver's footwell, under the dashboard, or under the hood. To find the exact location, turn on your turn signal and listen for a clicking or buzzing sound to help you pinpoint the source of the noise.

General locations

• Inside the cabin: Look for a fuse box in the driver's footwell or behind a panel under the dashboard. Some vehicles have the relay located in an electrical cluster in the footwell, near the steering column, or behind a storage compartment. 
• Under the hood: The relay may be in a fuse box located under the hood, near the battery. 
• On the back of the fuse box cover: The fuse box lid often has a diagram that labels the location of each relay, including the turn signal flasher.

How to find it

1. Turn on the turn signal: Activate your left or right turn signal and listen for the distinct clicking sound. 
2. Follow the sound: Get close to the fuse box and other electrical clusters. The relay will be the component making the loudest clicking or buzzing sound. 
3. Identify the relay: Once you have located the source of the sound, find the relay that matches your vehicle's specifications. You can compare it to the diagram on the fuse box cover if available.

Reference your vehicle's owner's manual to locate the turn signal relay. It is often located under the steering column. We recommend turning your flashers on and following the audible clicking noise.

What is the most common problem with a Subaru Outback?

Common problems for the Subaru Outback include weak windshields, excessive oil consumption, and issues with the cooling system and CVT transmission, especially in specific model years. Other frequent complaints involve airbag defects, electrical problems like battery drain, and vibration during acceleration.

Engine and powertrain 

• Excessive oil consumption: Many models, particularly older 2.5L engines, may burn oil between oil changes due to leaks from seals. 
• Cooling system failures: Overheating can lead to blown head gaskets, and the cooling system itself is a common point of failure. 
• CVT transmission problems: Some model years are more susceptible to issues like rough shifting or failure. 
• Vibration during acceleration: Some owners report a shudder or vibration when accelerating. 
• Older head gasket issues: The EJ-series engines (roughly 1997–2012) had an inherent head gasket failure problem, though this was mostly resolved in later models. 

Body and electrical

• Weak windshields: The glass is prone to cracking from stress or minor impacts. 
• Airbag defects: Some models have a history of airbag problems, leading to recalls. 
• Electrical issues: Problems can include unexpected battery drain and issues with the ABS control module. 

Other common issues

• Oxygen sensor failure: The front O2 sensor can fail, sometimes leading to a recall. 
• Premature brake wear: Some models experience faster-than-average brake wear. 
• Suspension wear and tear: Like many vehicles, suspension components will eventually wear out.
