Method 1: Clip-On Mirror
1. Inspect the mirror and mounting bracket: Carefully examine the back of the mirror and the windshield where the mirror attaches. You should see a small bracket or clips on the mirror's base. Also check the windshield for any broken or missing pieces of the mounting bracket.
2. Clean the mounting surface: Thoroughly clean both the back of the mirror and the windshield where the mirror attaches. Use glass cleaner and a lint-free cloth to remove any dust, dirt, or debris. Allow it to dry completely.
3. Align and attach: Carefully align the mirror's bracket with the windshield mounting point. Gently but firmly press the mirror onto the windshield until you hear or feel the clips snap into place. You may need to apply some pressure evenly across the base of the mirror.
4. Test the attachment: Gently tug on the mirror to ensure it's securely attached.
Method 2: Adhesive-Mounted Mirror
This is less common for rearview mirrors but possible. If the mirror is glued on:
1. Assess the damage: Determine if the old adhesive is still on the windshield and the mirror base. If so, you may need to carefully remove it using a plastic scraper, being very careful not to scratch the windshield. A commercial adhesive remover may also be helpful, but be cautious around the glass.
2. Clean the mounting surface: Thoroughly clean both surfaces. Use rubbing alcohol or a specialized glass cleaner designed for removing adhesive residue. Allow it to dry completely. This is crucial for good adhesion.
3. Apply new adhesive: Use a strong, automotive-grade adhesive designed for use on glass. Apply a small, even bead of adhesive to the back of the mirror base according to the adhesive's instructions.
4. Attach the mirror: Carefully position the mirror on the windshield, ensuring it's properly aligned. Apply firm, even pressure for the time recommended by the adhesive manufacturer (usually several minutes or more).
5. Secure the mirror: To prevent the mirror from shifting while the adhesive cures, you may want to use masking tape or a clamp to hold it in place. Allow the adhesive to fully cure before using the mirror.
If neither of these methods work:
* Check for broken parts: If any parts of the mounting bracket are broken, you'll need replacement parts. You can usually find these at an auto parts store. Provide the year, make, and model of your vehicle to ensure you get the correct part.
* Consider professional help: If you're uncomfortable working on this yourself, or if the mirror is damaged beyond simple reattachment, take your car to a professional auto glass repair shop.
Remember to always be gentle to avoid damaging the windshield. If you're unsure about any step, it's best to consult a professional.
