How to Fix Subaru Turn Signal Light Issues

Turn signals are a crucial safety feature in any vehicle, including your Subaru. They communicate your intentions to other drivers, allowing for safer lane changes and turns. However, like any other electrical component, turn signal lights can experience issues. When your Subaru’s turn signals malfunction, it’s essential to address the problem promptly to maintain road safety. In this article, we’ll explore common turn signal light issues in Subarus and how to fix them.

Common Turn Signal Light Issues

Before diving into solutions, let’s identify some of the typical turn signal light problems you might encounter with your Subaru:

  1. Bulb Failure: Burned-out bulbs are one of the most common causes of turn signal problems. A non-working bulb can result from a blown filament or a loose connection.
  2. Fast Blinking: If your turn signals blink at an unusually rapid rate (hyper-flashing), it’s often a sign that one of the bulbs is not working correctly.
  3. No Blinking: When your turn signal lever is engaged, and the lights stay solid without blinking, it’s a clear indication of a malfunction.
  4. Dim Lights: Dim or faint turn signal lights can make it challenging for other drivers to see your intentions, posing a safety risk.
  5. Rapid Clicking Noise: A rapid clicking noise from the turn signal relay can signal an issue, typically due to a faulty relay or a bulb problem.

How to Fix Subaru Turn Signal Light Issues

Now that we’ve identified the potential problems, let’s explore how to fix these issues:

  1. Replace Burned-Out Bulbs:
  • Step 1: Identify which turn signal is malfunctioning. Activate your hazard lights to see which bulb is not working.
  • Step 2: Locate the burned-out bulb. Access the bulb housing, typically by removing the lens cover or opening the hood or trunk, depending on the Subaru model.
  • Step 3: Carefully remove the old bulb by turning it counterclockwise or releasing the retaining clip, depending on the bulb type.
  • Step 4: Replace the old bulb with a new one of the correct type and wattage. Ensure it is securely in place.
  • Step 5: Test the turn signal to verify that the issue is resolved.
  1. Check and Clean the Contacts:
  • Step 1: If the bulb appears fine but still doesn’t work, inspect the contacts in the bulb socket. Corrosion or dirt can disrupt the electrical connection.
  • Step 2: Disconnect the negative battery terminal to ensure safety while working with electrical components.
  • Step 3: Use a small wire brush or sandpaper to gently clean the contacts in the bulb socket.
  • Step 4: Reconnect the battery and test the turn signal again.
  1. Address Rapid Blinking:
  • Step 1: Rapid blinking is often a sign of bulb failure. Follow the steps mentioned earlier to replace the malfunctioning bulb.
  • Step 2: If the problem persists after bulb replacement, check the wiring and socket for loose connections or damage.
  1. Replace the Turn Signal Relay:
  • Step 1: If you hear a rapid clicking noise coming from the turn signal relay and the bulbs are in good condition, the relay may be faulty.
  • Step 2: Locate the turn signal relay, typically under the dashboard or in the engine compartment. Refer to your owner’s manual for its exact location.
  • Step 3: Remove the old relay and replace it with a new one from an auto parts store. Ensure it’s the correct relay for your Subaru model.
  • Step 4: Test the turn signals to confirm that the issue is resolved.
  1. Seek Professional Assistance:
  • If you’ve tried the above steps and still cannot resolve the turn signal issue, or if you’re uncomfortable working with electrical components, it’s advisable to seek professional help. A certified Subaru technician can diagnose and repair complex electrical problems effectively.

In conclusion, addressing turn signal light issues in your Subaru involves a systematic approach, starting with bulb inspection and replacement. Regular maintenance and timely replacement of worn-out bulbs can help prevent most turn signal problems. However, if you encounter persistent issues or are unsure about the diagnosis, don’t hesitate to consult a Subaru dealership or an experienced automotive technician for expert assistance. Safe and properly functioning turn signals are essential for road safety, making it crucial to resolve any problems promptly.
