How to Replace the Glass in a Side Mirror

Damaged side mirror glass can significantly impair visibility and driving safety. Fortunately, replacing the glass is often a straightforward process, saving the cost of a complete mirror assembly replacement. This article provides a detailed guide on how to replace side mirror glass for most vehicle makes and models.

Gathering Necessary Tools and Materials

Before beginning the replacement process, gather the necessary tools and materials. This preparation ensures a smooth and efficient repair. The required items typically include:

Replacement mirror glass (ensure correct fit for the specific vehicle)
Small flat-head screwdriver or plastic pry tool
Gloves (optional, for hand protection)
Adhesive (if not pre-applied to the replacement glass)
Masking tape (optional, to protect surrounding areas)
Clean cloth
Glass cleaner

Accessing the Damaged Mirror Glass

Accessing the damaged mirror glass varies slightly depending on the vehicle model. Most modern vehicles utilize either a pry-out method or a pivoting method. Understanding the specific method for your vehicle is crucial to avoid damaging the mirror housing or internal components.

Pry-Out Method

For vehicles utilizing the pry-out method, carefully insert the flat-head screwdriver or pry tool between the outer edge of the mirror glass and the mirror housing. Gently apply pressure to release the clips holding the glass in place. Work around the perimeter of the mirror, releasing each clip sequentially. Once all clips are released, the mirror glass can be removed.

Pivoting Method

Some vehicles employ a pivoting method where the mirror glass can be angled inwards or outwards to gain access to the retaining clips. Consult your vehicle's service manual for the specific pivoting direction. Once the mirror is pivoted, access the retaining clips and carefully detach the damaged mirror glass.

Disconnecting Electrical Connectors (If Applicable)

Vehicles with features like heated mirrors or power adjustment have electrical connectors attached to the back of the mirror glass. Before removing the damaged glass completely, disconnect these connectors. Gently pull the connectors straight out, avoiding excessive force. If the connectors are difficult to detach, consult your vehicle's service manual for specific instructions.

Preparing the Mirror Housing

Once the damaged mirror glass is removed, clean the mirror housing thoroughly. Remove any broken glass fragments or old adhesive residue. A clean surface ensures proper adhesion of the replacement glass.

Applying Adhesive (If Necessary)

If the replacement mirror glass does not have pre-applied adhesive, apply a thin, even layer of automotive-grade adhesive to the designated areas on the back of the new glass or the mirror housing. Follow the adhesive manufacturer's instructions for proper application and curing time.

Installing the New Mirror Glass

Carefully align the new mirror glass with the mirror housing, ensuring proper placement within the retaining clips. Gently press the glass into place until it is securely held by the clips. For vehicles with electrical connectors, reconnect the connectors after the glass is secured.

Testing the New Mirror Glass

After installation, test the new mirror glass to ensure proper functionality. Adjust the mirror to verify the range of motion and check the operation of any features like heating or power adjustment.

Addressing Heated Mirror Functionality

If the vehicle has heated mirrors, ensure the heating element is functioning correctly after the replacement. Turn on the defroster and check for even heat distribution across the mirror surface. If the mirror does not heat up, check the electrical connections and consult your vehicle's service manual for troubleshooting steps.

Adjusting Power Mirror Functionality

For vehicles with power-adjustable mirrors, verify the functionality after installation. Use the power mirror controls to adjust the mirror in all directions. If the mirror does not respond to the controls, check the electrical connections and refer to your vehicle's service manual for troubleshooting guidance.

Cleaning the New Mirror Glass

Clean the new mirror glass with a suitable glass cleaner to remove any fingerprints or smudges. Ensure a clear and unobstructed view for optimal driving visibility.

Handling Different Mirror Types

Some vehicles utilize specialized mirror types, like aspherical or auto-dimming mirrors. These mirrors may require specific installation procedures. Consult your vehicle's service manual for detailed instructions related to these specialized mirror types.
