1. Identify the Cover:
* Look closely at the base of the mirror. You'll likely see a small, usually circular or slightly oval-shaped, decorative cover. It might be plastic or metal and may blend in with the mirror housing.
2. Remove the Cover:
* Gently pry it off. A small flathead screwdriver (wrapped in tape to protect the surface) or a plastic pry tool is ideal. Work your way around the perimeter, applying even pressure. The cover is usually just clipped in place, but be cautious as it can break.
3. Access the Retaining Clip:
* Once the cover is removed, you'll see the retaining mechanism. This is usually a metal clip or ring that holds the mirror to the windshield.
4. Release the Mirror:
* The clip usually needs to be compressed or manipulated. This is the trickiest part. You might need a small flathead screwdriver or specialized mirror removal tool to carefully compress the clips or lever the mirror free. Sometimes, gently pulling on the mirror itself, after locating the clip, can release it.
5. Remove the Button (If Applicable):
* The metal button is likely also part of the retaining mechanism. Once the mirror is free, examine the button. It might be clipped on, screwed on, or even glued. If clipped, carefully pry it off with a small flathead screwdriver or similar tool. If glued, you might need a small amount of heat (a hair dryer on low setting) to soften the adhesive.
Important Considerations:
* Windshield Damage: Be extremely careful not to scratch or chip the windshield during this process. Work slowly and deliberately.
* Clip Breakage: These clips are somewhat fragile. If it breaks, you may need to purchase a replacement. A local auto parts store might have them or you might find one online (be sure to specify your Windstar's year).
* Wire Connections: Some Windstar models have auto-dimming mirrors or other electronics. There may be wiring connected to the back of the mirror. If so, disconnect it *before* removing the mirror completely.
* Adhesive for Re-Attachment: Use a strong adhesive specifically designed for automotive glass. It's crucial for a secure and lasting bond.
If you're uncomfortable with this process, it's best to take your Windstar to a professional auto glass installer or repair shop. They have the tools and expertise to safely remove and re-attach the mirror without damaging the windshield. The cost will likely be minimal compared to the cost of replacing a damaged windshield.
