1. Identify the Mirror Type:
* Conventional Mirror (with a mounting bracket): These mirrors usually attach to the windshield with a bracket that either clips on or uses screws.
* Integrated Mirror (part of the headliner): These mirrors are more complex and often require professional repair if broken. They're usually wired into the car's electrical system.
* Automatic Dimming Mirror: These are typically more complex than standard mirrors and have internal electronics. Improper reattachment can damage them.
2. Determine Why it Detached:
* Loose Bracket: The most common reason. The bracket may have come loose from the windshield due to age, vibration, or impact.
* Broken Bracket: The bracket itself might be broken or damaged.
* Damaged Windshield: A cracked or damaged windshield may have compromised the mirror's mounting area.
* Electrical Failure (for auto-dimming mirrors): A wiring problem can prevent the mirror from working correctly, but isn't always a direct cause of detachment.
3. Reattachment Procedures (General Guidance - Always Consult Your Owner's Manual):
* Loose Bracket: If the bracket is intact but loose, you'll need to carefully re-secure it. This might involve:
* Cleaning the mounting surface: Thoroughly clean the windshield where the bracket attaches to remove dirt and debris.
* Using adhesive: For plastic clips, you might need a suitable adhesive (check your owner's manual for recommendations). Avoid using excessive adhesive. For screw-on brackets, ensure the screws are tight.
* Broken Bracket: This requires replacing the bracket, which may involve purchasing a replacement part from a Cadillac dealership or an auto parts store. This usually requires some disassembly.
* Damaged Windshield: Repairing the windshield is essential before reattaching the mirror. A cracked windshield can compromise the mirror's stability and safety.
4. Steps to take (if the bracket is intact and the problem is a loose fit):
1. Clean: Clean the windshield and the mirror's mounting bracket thoroughly. Use isopropyl alcohol or a glass cleaner.
2. Inspect: Carefully examine the bracket and the windshield for any damage. If there is damage, replacement parts are necessary.
3. Reattach: Carefully align the bracket with the windshield and firmly press it into place. If it has clips, ensure they snap securely. If it uses screws, tighten them gently to avoid over-tightening and damaging the windshield or the bracket.
4. Test: Gently test the mirror's stability. It should be securely attached and not wobble.
Important Considerations:
* Owner's Manual: Always consult your Cadillac's owner's manual for specific instructions on removing and reattaching your rearview mirror. It will have diagrams and important warnings.
* Professional Help: If you are unsure about any step, or if the mirror is an integrated or auto-dimming type, take your car to a qualified mechanic or Cadillac dealership. Incorrect reattachment could damage the mirror or the windshield.
* Safety: Never drive with a loose or insecure rearview mirror. It could fall off and cause an accident.
Without knowing the specific model and type of mirror, this is the most comprehensive advice possible. Remember to prioritize safety and consult your owner's manual.
