We reattach it with the **right adhesive**, or repair **auto-dimming** and wired mirrors. Rearview mirror repair at Route 66 Auto Repair in Upland covers the inside mirror: one that fell off the windshield in the heat, droops at every bump, or stopped auto-dimming. Most fallen mirrors can be reattached with the correct adhesive and mounting button. Mirrors with built-in wiring, compasses or cameras need more care, and our ASE-certified technicians check those before quoting in writing. ## What problems do rearview mirrors have? - The mirror and its button fell off the windshield - The mirror sags or shakes over bumps - Auto-dimming stopped working or the glass looks tinted all the time - A leak or bubble inside an auto-dimming mirror - The compass, temperature or garage buttons in the mirror went dark - A loose wiring cover above the mirror ## Why do rearview mirrors fall off? The mirror clips to a small metal button bonded to the glass. On a car parked in the sun, the windshield can get very hot and then cool quickly, and the bond weakens over time. Household superglue or the wrong adhesive usually fails the first hot week. If the button came off with a chip of glass, or the windshield is cracked near the mount, that is a glass issue first. See [windshield repair](https://route66autorepairshop.com/auto-body-and-glass-services/windshield-repair) for how we handle that. Many newer windshields also carry a camera bracket beside the mirror, which we check and leave undisturbed. ## Our rearview mirror repair process 1. **Check the mount and glass:** We look at the button, the glass behind it and any camera bracket nearby. 2. **Clean and prepare:** Old adhesive is removed and the glass is cleaned so the new bond can grip. 3. **Bond the button:** The button is set in the factory position with adhesive made for mirror mounts and allowed to cure. 4. **Mount and test:** The mirror is attached, wiring is reconnected, and dimming and other features are tested. ## What's included in rearview mirror repair - Inspection of the mount button and surrounding glass - Old adhesive removal and glass prep - Button bonding with mirror-mount adhesive - Mirror installation and wiring connection - Auto-dimming and feature test where equipped - Wiring cover refit ## Is rearview mirror repair a need-now or need-later repair? **Need now:** - A mirror that fell off, leaving no rear view - A mirror that shakes so much you cannot see behind you **Need later:** - Auto-dimming that stopped but the mirror still reflects - A dead compass or temperature display ## How pricing and timing work Reattaching a basic mirror is a small job, though the adhesive needs cure time. Replacing an auto-dimming or wired mirror costs more because of the part. Your written estimate states which applies. AAA members get 10% off parts and labor, up to $75, with the card. Most reattachments can be done while you wait when the board allows; call before you drive over. ## Aftercare after a rearview mirror repair Adjust the mirror gently for the first day while the bond finishes curing. A sunshade helps keep the windshield cooler. If it loosens again, bring it back and it goes to the front of the line. For outside mirrors, see [side mirror replacement](https://route66autorepairshop.com/auto-body-and-glass-services/side-mirror-replacement). Dim or flickering mirror lights can trace back to [wiring problems](https://route66autorepairshop.com/electrical-services/wiring-harness-repair). ## Frequently asked questions ### Can I glue my rearview mirror back on myself? You can with a proper mirror mount kit and careful prep. The usual failures come from using household glue, not cleaning off the old adhesive, or setting the button in the wrong spot. Heat then pops it off again. ### My mirror fell off with a piece of glass. Now what? That means the windshield itself was damaged at the mount. We check the glass first, because bonding to a chipped spot will not hold and the chip may spread. ### Why is my auto-dimming mirror always dark? The gel between its glass layers can leak or break down, which leaves the mirror tinted or blotchy. That usually means replacing the mirror. We confirm the wiring is good first. --- Call (909) 608-7699 or visit https://route66autorepairshop.com/contact for a written estimate.
