What are common causes of horn issues in the 2016 Subaru Outback?

The most common causes of horn issues in the 2016 Subaru Outback include a blown fuse, faulty horn relay, or a malfunctioning horn itself. The fuse protects the horn circuit, and if it is blown, the horn will not work. The relay serves as a switch to send power to the horn when it is activated. If either of these components fails, it can prevent the horn from functioning properly.

Additionally, issues with wiring, such as frayed or damaged wires, can also lead to horn malfunctions. It’s important to check the connection points for corrosion or loose connections, as these can disrupt power flow. Lastly, problems with the steering wheel or horn button, such as a worn contact pad, may contribute to the issue, requiring a more in-depth inspection.

How can I check if the horn fuse is blown?

To check if the horn fuse is blown, first locate the fuse box in your Subaru Outback, which is typically found under the dashboard on the driver’s side or in the engine compartment. Once you have located the fuse box, refer to the fuse diagram that is usually located on the cover or in the owner’s manual to identify the specific fuse for the horn.

After identifying the horn fuse, remove it using a fuse puller or a pair of needle-nose pliers. Inspect the fuse for any visible signs of damage, such as a broken filament. If the filament is broken or the fuse appears discolored, it is likely blown and will need to be replaced. Make sure to replace it with a fuse of the correct amperage to ensure proper functioning.

What should I do if the horn relay is faulty?

If you suspect that the horn relay is faulty, you can perform a simple swap test with another relay of the same type within the fuse box, if available. First, identify the horn relay as indicated in the owner’s manual or fuse box diagram. Carefully remove the relay and replace it with a similar relay that is functioning and is used by a less critical system, like the headlights or another accessory.

If replacing the relay resolves the horn issue, you will need to purchase a new horn relay to ensure long-term functionality. If the horn still does not work after the relay is replaced, further investigation may be necessary, including checking the wiring and the horn itself for defects.
