How To Replace The Mirror Glass On Side View

How to Replace the Mirror Glass on a Side View Mirror

Damaged or broken side view mirror glass can significantly impair driving visibility and pose a safety risk. Fortunately, replacing the glass is often a manageable DIY task that can save considerable expense compared to replacing the entire mirror assembly. This guide provides a comprehensive walkthrough of the replacement process.

Tools and Materials: Before beginning, gather the necessary tools and materials. These typically include a replacement mirror glass (ensure correct fit for the vehicle's year, make, and model), a small flathead screwdriver or pry tool, protective gloves, a soft cloth, adhesive (if not pre-applied to the replacement glass), and masking tape.

Step 1: Safety Precautions: Prioritize safety by wearing protective gloves throughout the process to prevent cuts from broken glass. It's also advisable to disconnect the vehicle's battery negative terminal to avoid any potential electrical issues.

Step 2: Accessing the Damaged Mirror Glass: The method for accessing the damaged mirror glass varies slightly depending on the vehicle model. Some mirrors have small access panels behind the mirror assembly, allowing access to the clips or screws securing the glass. Others require gently prying the edge of the broken mirror glass away from the housing. Consult the vehicle's owner's manual for specific instructions.

Step 3: Removing the Damaged Mirror Glass: Once access is gained, carefully disconnect any wiring harnesses connected to features like heated mirrors or power adjustment. If the mirror is held by clips, carefully release them using a small flathead screwdriver or pry tool, working around the perimeter of the glass. If screws are present, remove them using an appropriate screwdriver. Take care not to damage the mirror housing or any internal components.

Step 4: Cleaning the Mirror Housing: With the broken glass removed, thoroughly clean the mirror housing surface where the new glass will be adhered. Remove any remaining adhesive residue, dirt, or debris using a clean cloth. A clean surface ensures optimal adhesion of the new mirror glass.

Step 5: Preparing the Replacement Mirror Glass: If the replacement mirror glass comes with pre-applied adhesive, carefully remove the protective backing. If adhesive is not pre-applied, follow the manufacturer's instructions for applying the adhesive to the back of the new mirror glass. Ensure the adhesive is evenly distributed for a secure bond.

Step 6: Installing the Replacement Mirror Glass: Carefully align the new mirror glass with the mirror housing, ensuring it sits flush and evenly within the frame. Apply firm, even pressure to the back of the mirror to secure the adhesive. If clips are used, ensure they are properly engaged and secured. If screws were removed, replace them and tighten them securely, but avoid over-tightening, which could crack the new glass.

Step 7: Reconnecting Wiring Harnesses: If the mirror has features like heating or power adjustment, reconnect any previously disconnected wiring harnesses. Ensure the connections are secure and properly seated.

Step 8: Testing the New Mirror Glass: Reconnect the vehicle's battery negative terminal and test the functionality of the new mirror glass. Adjust the mirror to ensure proper positioning and check that any heated mirror features are working correctly. Verify that the power adjustment function (if applicable) is operating smoothly.

Alternative Method: Using a Suction Cup: Some replacement mirror glass kits come with a suction cup tool to aid in removal and installation. Attach the suction cup firmly to the center of the broken glass. Gently pull and wiggle the suction cup while applying pressure to the edges of the mirror with a pry tool to release the clips or adhesive. The suction cup can also be used to position and secure the new mirror glass.

Addressing Common Challenges: Difficulty removing the old glass can sometimes arise due to stubborn adhesive or tightly secured clips. Applying gentle heat using a hairdryer can soften the adhesive, making removal easier. Patience and careful maneuvering are crucial to avoid damaging the mirror housing. If significant resistance is encountered, consulting a professional auto glass technician is recommended.

Choosing the Right Replacement Glass: Selecting the correct replacement mirror glass is essential for proper fit and functionality. Ensure compatibility by checking the vehicle's year, make, and model when ordering the replacement glass. Consider features like heated mirrors, blind spot monitoring, or auto-dimming functionality when choosing a replacement.

Maintaining Side View Mirrors: Regularly cleaning the side view mirrors with a mild glass cleaner can help maintain visibility and prevent buildup of dirt and grime. Avoid using abrasive cleaners or materials that could scratch the mirror surface. Inspect the mirrors periodically for any signs of damage or loosening and address issues promptly to ensure optimal safety and visibility.
