1. The mirror simply fell off its mounting bracket:
* Check the Mounting Bracket: Carefully inspect the bracket on the windshield and the back of the mirror. Look for broken plastic clips or stripped threads. The mirror likely attaches to the bracket using a simple clip, a threaded bolt, or a combination.
* Reattach the Mirror: If the clips are broken, you might need to use a strong adhesive (like automotive-grade epoxy or windshield adhesive specifically designed for this purpose) to reattach the mirror to the bracket. If the threads are stripped, you might need to replace the bracket itself. A new bracket might require a trip to a junkyard or a parts store.
* Clean the Surfaces: Before applying any adhesive, thoroughly clean both the bracket and the back of the mirror with isopropyl alcohol to ensure a good bond.
2. The mounting bracket itself broke off the windshield:
* This is a more serious problem. The bracket is likely glued or adhered to the windshield. Replacing the bracket requires careful removal of the old adhesive, cleaning the windshield surface thoroughly, and then using a new bracket and a strong adhesive designed for automotive windshields. This is a more involved repair and might be best left to a professional auto glass shop. Improper repair could compromise the integrity of the windshield.
3. The mirror is electrically powered (auto-dimming or heated):
* Electrical Connections: In addition to the mechanical attachment, these mirrors have electrical wiring connectors. Be extremely careful when handling these to avoid damage. Consult a repair manual or online resources for diagrams showing how the wires connect. Incorrect reconnection may damage the mirror or vehicle's electrical system.
Important Considerations:
* Safety First: Before attempting any repairs, ensure the vehicle is parked safely and the ignition is off.
* Repair Manual: A repair manual specific to your 1995 Chevy Lumina will provide detailed diagrams and instructions. You can often find these online (though some are paywalled).
* Professional Help: If you're uncomfortable with any aspect of the repair, it's best to take your vehicle to an auto glass repair shop or a qualified mechanic. Incorrect repair could lead to further damage or create a safety hazard.
Without knowing exactly how your mirror detached, it's impossible to give a precise solution. Carefully examine the mirror and its attachment to determine the cause of the problem before attempting repairs. A picture would be helpful to get more specific advice.
