How To Replace The Glass On A Car Mirror

Replacing a broken or damaged car mirror glass is a relatively simple and cost-effective repair that can be done at home with a few basic tools. This guide provides a step-by-step process for replacing the glass on both manual and power-adjustable car mirrors.

Gathering Necessary Tools and Materials

Before starting the replacement process, gather the following items: * Replacement mirror glass (ensure it matches the car’s make, model, and year) * Flathead screwdriver or plastic pry tool * Gloves * Safety glasses * Mirror adhesive (if not pre-applied to the replacement glass) * Masking tape (optional) * Small hammer (optional)

Preparing the Work Area

Choose a well-lit and clean work area. If working outdoors, ensure the area is protected from wind and debris. Covering the car door panel near the mirror with masking tape can protect it from scratches during the removal process.

Removing the Old Mirror Glass (Manual Mirror)

For manual mirrors, the process is generally straightforward: * Carefully insert the flathead screwdriver or pry tool between the mirror glass and the mirror housing. * Gently pry the mirror glass outward. Start at one corner and work your way around the perimeter, applying even pressure to avoid cracking the glass further. * Once the clips holding the mirror are released, the glass should come off. If the mirror is heavily damaged, wear gloves to protect hands from sharp edges.

Removing the Old Mirror Glass (Power Mirror)

Power mirrors require a slightly different approach: * Adjust the mirror to its furthest position, either up, down, left, or right, to expose the clips holding the glass in place. * Insert the pry tool between the glass and housing at the exposed edge. * Gently pry the mirror glass outward. Increased resistance might be encountered due to the motor’s wiring. Work slowly and cautiously to avoid damaging the internal components. * Once the clips are released, carefully disconnect the wiring harness connected to the back of the mirror glass. Take note of the connector’s orientation for reattachment.

Cleaning the Mirror Housing

Once the old mirror glass is removed, clean the mirror housing thoroughly to ensure proper adhesion of the new glass. Remove any remaining adhesive residue from the old mirror and clean the surface with a suitable glass cleaner.

Installing the New Mirror Glass (Adhesive Application)

If the new mirror glass doesn’t come with pre-applied adhesive, follow these steps: * Apply a thin, even layer of mirror adhesive to the back of the new mirror glass or the designated areas on the mirror housing, following the adhesive manufacturer’s instructions. * Ensure the adhesive covers the entire contact area for a secure bond.

Installing the New Mirror Glass (Attachment)

Whether the mirror is manual or power, the attachment process is similar: * Carefully align the new mirror glass with the mirror housing, ensuring proper placement. * Firmly press the mirror glass onto the housing, applying even pressure across the surface. * Hold the glass in place for the time recommended by the adhesive manufacturer or until a secure bond is established. * For power mirrors, reconnect the wiring harness to the back of the new mirror glass, matching the connector’s orientation.

Testing the New Mirror Glass (Power Mirrors)

After installation, test the power mirror functionality: * Turn on the car’s ignition. * Adjust the mirror in all directions to ensure it moves smoothly and correctly. * Check for any unusual noises or resistance during operation.

Final Adjustments and Precautions

After installation: * Remove any masking tape used to protect the car door panel. * Clean the new mirror glass with a glass cleaner. * Avoid excessive force when adjusting the mirror to prevent damage. * If encountering difficulties during any stage of the replacement process, consult a professional mechanic or automotive glass specialist.
