Procedure:

1. Safety Precautions:
   • Ensure the vehicle is parked safely, the engine is turned off, and the handbrake is engaged.

   • Apply gentle pressure and carefully pry the old mirror glass away from the housing.
3. Warming the Adhesive:

   • 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.
