  • Flathead screwdriver
  • Heat gun or hairdryer (for warming the adhesive)
  • Razor blade or plastic trim tool
  • Cleaning solution and a soft cloth
  • Safety equipment (gloves, safety glasses)

Procedure:

  1. Safety Precautions:
    • Ensure the vehicle is parked safely, the engine is turned off, and the handbrake is engaged.
    • Wear safety gloves and glasses to protect your hands and eyes.
  2. Remove the Old Mirror Glass:
    • Gently insert a flathead screwdriver or a plastic trim tool between the old mirror glass and the plastic housing. Be cautious not to damage the plastic housing.
    • Apply gentle pressure and carefully pry the old mirror glass away from the housing.
  3. Warming the Adhesive:
    • If the mirror glass is firmly attached, you can use a heat gun or a hairdryer to warm the adhesive on the back of the mirror. This will make it easier to remove. Be cautious not to overheat the glass or housing.
    • Heat the adhesive by moving the heat source back and forth over the mirror’s surface. Do not focus the heat in one area for too long.
  4. Peel Off the Old Mirror Glass:

  5. Clean the Housing:
    • Clean the plastic housing with a suitable cleaning solution and a soft cloth. Remove any remaining adhesive residue.
  6. Prepare the Replacement Glass:
    • Ensure the replacement mirror glass is clean and free of any dust or debris. You can wipe it with a clean, dry cloth to be sure.
  7. Attach the Replacement Glass:
    • Carefully position the replacement mirror glass onto the plastic housing, aligning the attachment points.
    • Press the glass firmly to adhere it to the housing. Apply even pressure to ensure proper adhesion.
  8. Final Inspection:
    • Carefully inspect the replacement mirror glass to ensure it’s securely attached and properly aligned within the housing.
  9. Test the Mirror:
    • From inside the vehicle, test the mirror’s functionality by adjusting it to ensure it provides a clear and accurate reflection.
  10. Adjust the Mirror Position:
    • Adjust the mirror to the desired position for optimal visibility.
