Why is my right turn signal not working?

  1. Inspect the Green Wire:
    • This wire runs from the main trailer plug to the right tail light. Look for any pinched or sliced sections.
  2. Check the White Ground Wire:
    • Behind the tail light, ensure the white ground wire is securely connected to the metal bracket.
  3. Examine the Bulbs:
    • If your tail light uses CEC 1157 or C193 bulbs, make sure both are functioning properly.
  4. Look for Corrosion:
    • Excessive corrosion in the light fixture may mean it’s time to replace the tail light.
  5. LED Tail Lights:
    • If you have LED tail lights, they are not serviceable. Replace the entire unit if any diodes stop working.
