How To Replace Car Door Mirror Glass

Replacing a broken or cracked car door mirror glass is a relatively straightforward task that can save you money compared to having a mechanic do it. This guide provides a step-by-step process for replacing the glass, covering the essential tools and techniques for a successful repair.

Gather Your Supplies

Before starting the replacement process, gather the necessary tools and materials. These include:

Replacement mirror glass: Ensure you purchase the correct mirror glass for your car model and side.
Torx screwdriver: Most car door mirrors use Torx screws, which require a Torx screwdriver for removal.
Phillips screwdriver: Some vehicles might use Phillips head screws for the mirror assembly.
Flathead screwdriver: This is useful for prying off the cover or trim around the mirror assembly.
Small hammer: A small hammer can be helpful for gently tapping the new mirror glass into place.
Cleaning cloth: Wipe down the mirror surface and surrounding area to remove dirt and debris.
Gloves (optional): Wearing gloves can protect your hands from scratches and grease.

Remove the Existing Mirror Glass

The steps for removing the existing mirror glass vary depending on the car model, but the general process is as follows:

Secure the vehicle: Park the vehicle on a level surface and engage the parking brake.
Remove the mirror cover or trim: Gently pry off the cover or trim around the mirror assembly using a flathead screwdriver. Begin at one corner and carefully work your way around the perimeter.
Locate the mirror glass retaining clips or screws: The mirror glass is typically held in place by either clips or screws.
- Clips: If the mirror glass is held in place by clips, use a flathead screwdriver to gently pry off the clips.
- Screws: If screws are used, remove them using the appropriate screwdriver.
Remove the old mirror glass: Carefully remove the old mirror glass from the assembly. You might need to gently pull or twist it free.

Install the New Mirror Glass

Once the old mirror glass is removed, install the new glass following these steps:

Align the new mirror glass: Carefully align the new mirror glass with the existing housing or assembly. Ensure it sits flush and that the mounting points are correctly aligned.
Secure the new mirror glass: Reinstall the retaining clips or screws that held the old mirror glass in place. If using clips, gently push them into place until they are secure. If using screws, tighten them securely but avoid over-tightening.
Reattach the cover or trim: Carefully snap or clip back the cover or trim around the mirror assembly.

Tips for Successful Mirror Glass Replacement

Here are a few tips to make the mirror glass replacement process smoother:

Inspect the mirror housing: Before installing the new mirror glass, inspect the mirror housing for any damage or wear. Replacing a damaged housing can prevent future problems.

Clean the mirror glass: Before installing the new mirror glass, clean the glass with a cleaning cloth to remove any smudges or fingerprints.
