How do you replace wing mirror glass on a citroen c4?

To replace the wing mirror glass on a Citroën C4, start by carefully prying off the glass using a flat tool, ensuring not to damage the backing. Once the old glass is removed, clean the surface, then align the new mirror glass with the backing and press it firmly into place until it clicks. Reattach any covers or components if necessary, and test the new mirror for proper positioning. Always consult your vehicle's manual for specific instructions or safety precautions.
