Where is the blower motor relay on a 2015 Subaru Legacy?
In a 2015 Subaru Legacy, the blower motor relay is typically located in the interior fuse/relay box on the passenger side, behind the glove box. The relay is usually labeled BLOWER or BLWR on the panel diagram, though exact labeling can vary by trim or region. If in doubt, consult the owner's manual diagram for the precise location.
The blower motor relay controls the HVAC blower by energizing the blower motor through the HVAC control circuit. When the relay fails, the blower may not operate at all or may work intermittently. Accessing the relay generally involves removing the interior fuse panel cover and locating the relay by its label on the diagram. In some late-model Subarus, a second location under the hood or in a secondary fuse/relay box is possible, but the interior box behind the glove box is the primary target for a 2015 Legacy.
Where to look for the blower motor relay
The following guidance helps you locate and verify the blower motor relay in most 2015 Legacy vehicles. Always refer to the exact diagram in your car’s fuse box cover or the owner’s manual for the precise label.
- Open the passenger-side footwell and remove the fuse panel cover to access the interior fuse/relay box.
- Use the diagram on the inside of the cover (or the owner’s manual) to identify the relay labeled BLOWER, BLOWER MOTOR, or BLWR. This is the HVAC blower relay.
- With the ignition off, pull the relay out and inspect its terminals. If you have a known-good, identical relay from the same box, swap it in to test whether the blower operation returns.
- If you hear a reliable click from the relay when the ignition is turned on and the blower begins to operate, the relay is likely functioning. If there is no click and the blower still doesn’t work, the relay or the circuit may be faulty and require further testing.
Note: If your model year has the blower relay in a different box (such as a secondary under-hood relay box or a separate HVAC module), you may need to check that location as well. Always disconnect the battery before removing any fuse/relay to avoid short circuits or accidental airbag deployment.
Additional tips and testing options
For a more thorough diagnosis, also test the blower motor itself and the resistor assembly, since a failed motor or resistor can mimic relay problems. If you have a multimeter, you can check the relay coil resistance and, with proper safety procedures, temporarily power the blower directly to verify operation. If you are not confident performing electrical tests, seek professional assistance.
Summary
On a 2015 Subaru Legacy, the blower motor relay is most commonly found in the interior fuse/relay box behind the passenger-side dash near the glove box, labeled BLOWER or BLWR on the diagram. If your vehicle doesn’t exhibit blower operation, check this relay first, then consider testing the blower motor and resistor. When in doubt, consult the owner’s manual or a qualified technician for precise location and safe testing procedures.
