How To Remove Broken Side Mirror Glass

A broken side mirror can be a significant inconvenience, obstructing the driver's view and posing a safety hazard. While replacing the entire mirror assembly might seem like the only solution, often only the glass needs replacement. This guide provides a step-by-step approach to removing broken side mirror glass, saving time and money.

1. Gather Necessary Tools and Materials

Before beginning the removal process, gather the following items: thick work gloves, safety glasses, a small pry tool (such as a putty knife or panel removal tool), masking tape, a screwdriver (if necessary), and a replacement mirror glass that matches the vehicle's make and model. Having these materials readily available will streamline the process and ensure safety.

2. Secure the Work Area

Broken glass fragments can be sharp and dangerous. To prevent injury and contain the debris, wear thick work gloves and safety glasses throughout the process. Cover the interior door panel and any exposed areas near the mirror with masking tape or a drop cloth to protect them from scratches and stray glass pieces. Placing a towel or drop cloth beneath the mirror will also help collect falling shards.

3. Assess the Damage and Mirror Type

Examine the damaged mirror to determine the extent of the breakage and the type of mirror attachment. Some mirrors are glued directly to the backing plate, while others are held in place with clips or screws. Understanding the attachment method will inform the appropriate removal technique. If the mirror is severely shattered, additional caution should be exercised to avoid further fragmentation.

4. Removing Glued Mirrors

For mirrors glued directly to the backing plate, carefully insert the pry tool between the glass and the backing plate. Start at a corner or edge where the glass is already broken, providing a point of entry. Apply gentle, even pressure to pry the glass away from the backing plate. Work slowly and methodically around the perimeter of the mirror, gradually separating the adhesive. If the adhesive is particularly strong, a heat gun or hairdryer can be used to soften it, making removal easier. Use caution with heat to avoid damaging the mirror housing or other components.

5. Removing Clipped or Screwed Mirrors

If the mirror is held in place with clips or screws, locate and remove these fasteners. Consult the vehicle's owner's manual for specific instructions regarding the location and type of fasteners. Once the fasteners are removed, the mirror glass should easily detach from the backing plate. If the mirror is resistant, gently pry it loose using a small pry tool. Exercise caution to avoid damaging the clips or the backing plate during removal.

6. Clean the Backing Plate

After removing the broken glass, thoroughly clean the backing plate to remove any remaining adhesive residue or glass fragments. A plastic scraper or adhesive remover can be used for stubborn adhesive. Ensure the surface is clean and dry before installing the replacement mirror glass. This will ensure proper adhesion and prevent future issues.

7. Preparing for Replacement

Once the backing plate is clean, carefully examine the wiring for any damage, particularly if the mirror has heated elements. If any damage is found, consult a professional for repair before proceeding. Refer to the instructions that came with the replacement mirror glass for specific installation guidance. Different mirrors may have specific requirements, such as the use of specific adhesives or alignment procedures.

Replacing a broken side mirror glass is a manageable task that can be completed with the right tools and approach. Following these steps will ensure a safe and successful removal process, preparing the mirror housing for the installation of a new glass.
