Removing the mirror
Removing the rearview mirror can be a simple task. However, it is important to be cautious and patient throughout the process. Here is a step-by-step guide to help you remove the mirror safely and efficiently:
Prepare the Necessary Tools and Materials:
Before beginning the removal process, ensure you have gathered all the required tools and materials. These may include a screwdriver, razor blade, window cleaner, paper towels, and a hairdryer. Having these items ready will make the process smoother and help you avoid any delays.
Disconnect Electrical Connectors (if applicable):
If your rearview mirror has electrical components, such as an electronic compass or dimming feature, start by disconnecting the electrical connectors. This step is crucial to prevent any damage to the electrical system and to ensure your safety. Make sure to consult your vehicle's manual or seek guidance from an expert if you're unsure about the electrical aspects.
Loosen and Remove the Mounting Screw:
Use a screwdriver to loosen and remove the screw that holds the mirror arm to the mount on the windshield. This screw is typically located at the base of the mirror arm. Once the screw is removed, the mirror should be free to slide off or detach from the mount. Be gentle during this step to avoid accidental breakage.
Warm the Windshield:
It is recommended to apply heat to the windshield, especially if your mirror is glued to it. You can use a hairdryer for this purpose. Warming the windshield helps to soften the glue, making it easier to remove the mirror without leaving excessive residue. Ensure you direct the heat evenly across the area where the mirror is attached.
Carefully Detach the Mirror:
With the screw removed and the windshield warmed, you can now carefully detach the mirror from the glass-mounted hardware. Gently slide the mirror off the mount or clip, being cautious not to apply excessive force. If the mirror is glued, slowly and carefully lift it away from the windshield, being mindful of any remaining adhesive. Use a razor blade to scrape away any stubborn adhesive residue, but exercise caution to avoid scratching the glass.
Clean the Windshield:
Once the mirror is removed, clean the area of the windshield where the mirror was attached. Use window cleaner and paper towels to ensure that any remaining adhesive residue, dirt, or grime is removed. This step is crucial for preparing the surface for the new mirror installation.
Remember to work carefully and patiently throughout the removal process. If you encounter any complex electrical components or are unsure about a specific step, consider seeking guidance from a professional or consulting a vehicle repair specialist.

Using glue or adhesive
Fixing a broken electrical rearview mirror using glue or adhesive is a quick and simple DIY job. Here is a step-by-step guide to help you through the process:
Prepare the Work Area and Materials:
Firstly, ensure you have the right adhesive for the job. Ordinary super glues, epoxies, and non-specific adhesives are not suitable, as they are not strong enough for long-term use. Instead, look for adhesives specifically designed for rearview mirrors or automotive use. These adhesives often come with an activator solution that helps the adhesive bond faster and stronger.
Prepare your work area by parking your car in a well-ventilated area, either outdoors or in an open garage. Maintain a comfortable temperature between 50 and 75 degrees Fahrenheit. If it's too hot, the adhesive may cure with less strength, and if it's too cold, it may take longer to set.
Clean and Prepare the Surfaces:
Before applying the adhesive, clean both the mounting button and the windshield glass surface. Use a new razor blade to scrape away any old glue or residue from the mounting button and windshield. Be sure to scrape away from yourself to avoid injury. Then, use a cleaner or activator towelette to wipe down the marked area on the inside of the windshield. Allow the area to dry completely before proceeding.
Apply the Adhesive:
Now, it's time to apply the adhesive. Refer to the instructions on your chosen adhesive for specific application guidance, as methods may vary slightly between products. Generally, you will only need a small amount of adhesive, typically one or two drops, applied to the center of the mounting button or the back of the mounting bracket.
Attach the Mounting Button:
Immediately after applying the adhesive, attach the mounting button to the windshield. Ensure that the button is oriented correctly, with the round end at the top and the flat side against the glass. Firmly hold the button in place for at least 60 seconds to ensure a strong bond.
Reattach the Mirror Bracket:
Once the adhesive has cured, reattach the mirror bracket to the mounting button. Again, refer to the instructions for the specific curing time of your adhesive. Some adhesives may recommend waiting 15-30 minutes, while others suggest 24 hours for maximum strength.
Final Adjustments:
After the adhesive has cured, and the mirror bracket is secure, you can make any final adjustments. Check the position of the mirror and ensure it is level and at the desired height. If your mirror has electrical components, don't forget to reconnect any wires.
By following these steps and paying close attention to the instructions on your chosen adhesive, you can confidently fix your broken electrical rearview mirror using glue or adhesive.

Fixing a loose mirror
If your rearview mirror is loose, it is likely that the mirror socket is no longer holding the ball mount in place. This is due to the plastic teeth that usually hold the ball joint in place breaking off, resulting in the mirror sagging.
To fix this, you will need to remove the rearview mirror. First, place a piece of tape on the outside of the windshield to mark the mirror's exact location. Next, remove the screw that holds the arm to the mount on the windshield using a screwdriver. Once the screw is removed, the mirror can slide off and be removed. Before removing the mirror, ensure that you remove any electrical connectors.
Now, you will need to address the broken plastic teeth. One solution is to use a latex glove, cutting off one of the fingertips and fitting it over the tip of the ball joint before inserting it back into the socket. However, this solution is not durable and the glove will likely break apart once you start moving the mirror around.
A more durable solution is to purchase a rearview mirror repair kit, which includes a replacement mounting tab. Clean the mounting tab thoroughly, removing any old glue. Apply glue or adhesive to the tab and attach it to the windshield, aligning it with the tape marking. Once the tab is secure, mount the rearview mirror again.
