Replacing the wing mirror glass on a Mercedes W201 is a simple DIY task that can restore visibility and safety. Follow these steps to complete the job safely and effectively.

Tools and Materials Required
  • Replacement wing mirror glass
  • Flathead screwdriver or plastic trim tool
  • Heat gun or hairdryer (for loosening adhesive)
  • Razor blade or plastic scraper
  • Cleaning solution and a soft cloth
  • Safety gloves and glasses
Procedures:
1. Safety First
  • Park the vehicle on level ground and ensure the engine is off.
  • Engage the handbrake.
  • Put on safety gloves and glasses to protect your hands and eyes.
2. Remove the Old Mirror Glass
  • Carefully insert a flathead screwdriver or plastic trim tool between the mirror glass and its housing.
  • Gently pry the mirror away, taking care not to crack the housing or frame.
3. Soften the Adhesive (if necessary)
  • If the glass is firmly attached, use a heat gun or hairdryer to gently warm the adhesive behind the glass.
  • Move the heat source evenly across the surface — do not focus on one spot for too long to avoid heat damage.
4. Detach the Old Glass
  • Once the adhesive softens, use a razor blade or plastic scraper to lift and remove the old glass.
  • Dispose of the broken glass safely.
5. Clean the Housing
  • Wipe the housing area with a cleaning solution and soft cloth to remove adhesive residue or dirt.
  • Ensure the surface is completely clean and dry before fitting the new glass.
6. Prepare and Install the New Mirror Glass
  • Check that the replacement glass is clean and free of dust.
  • Align it carefully with the mounting points on the housing.
  • Press the glass firmly and evenly to ensure proper adhesion.
7. Final Inspection and Adjustment
  • Check that the new mirror glass is securely in place and properly aligned.
  • From inside the car, test the mirror adjustment controls to confirm smooth movement.
  • Adjust the mirror to your preferred viewing angle for optimal visibility.
