Is your Subaru Legacy or Outback's driver-side mirror acting up? Here's how to tell if it's failing and what might be causing the problem.
Warning Signs of a Failing Side Mirror with Turn Signal:
- The turn signal in the mirror doesn't light up.
- The mirror doesn't adjust properly.
- The mirror is loose or wobbly.
- The mirror glass is cracked or broken.
- The mirror housing is damaged.
Testing the Mirror:
- Check the turn signal: Activate the left turn signal and see if the light in the mirror comes on. If not, it could be a bulb, wiring, or the mirror itself.
- Test the mirror adjustment: Use the interior controls to adjust the mirror up, down, left, and right. If it doesn't move or moves erratically, the motor or wiring might be faulty.
- Inspect the wiring: Look for any damaged or frayed wires connected to the mirror.
- Check the mirror's connection: Ensure the mirror is securely attached to the door. A loose connection can cause problems.
Common Failure Causes:
- Impact damage: Getting hit by another car, hitting an object, or even vandalism can damage the mirror.
- Electrical problems: Wiring issues, blown fuses, or a faulty motor can cause the turn signal or adjustment functions to fail.
- Wear and tear: Over time, the motor or other components can wear out.
- Water damage: Water can get inside the mirror housing and corrode the electrical components.
