Subaru 86111AG010 Turn & Hazard Unit

When the turn signal switch is actuated, the flasher unit activates the turn signal lights, while the hazard flasher switch causes all four turn signal lights to flash simultaneously. An audible click is heard when the flasher unit operates correctly; if the turn signals fail on one side and the clicking sound is absent or if the flashing is much more rapid than usual, a faulty turn signal bulb is likely. If both turn signals do not blink, the issue may stem from a blown fuse, a faulty flasher unit, a broken switch, or a loose or open connection. A quick check of the fuse box can reveal a blown turn signal fuse, and it is advisable to inspect the wiring for a short before replacing the fuse. To remove the flasher, take off the knee bolster and reinforcement panel behind it, unplug the electrical connector from the flasher unit, and then remove the mounting bolt, with installation being the reverse of removal.

To test a normally-open relay, an ohmmeter can be used to check for continuity between specific terminals in different power and ground configurations.

The problem may be due to a blown fuse, a faulty flasher unit, a broken switch, or a loose or open connection.

If the relay fails the test, it should be replaced.

The flasher unit flashes the turn signal lights.

Yes, there are some relays mounted on or near the passenger compartment fuse box, but they are not visible until the knee bolster is removed.
