Tools you'll likely need:
* New mirror: Ensure you purchase the correct replacement mirror for your Astro's year, model, and side (driver's or passenger's).
* Phillips head screwdriver (possibly a Torx): This will depend on the type of screws holding the mirror housing to the door.
* Possibly a trim removal tool: Plastic trim tools help prevent scratching the door panel during removal. These are often flat, thin tools, and you can improvise with something similar if you don't have them (but use caution!).
Steps:
1. Power Down: Turn off the vehicle and disconnect the negative terminal of the battery. This is a safety precaution to prevent electrical shocks.
2. Locate the Mirror Mounting Screws: The screws holding the mirror assembly to the door are usually found behind a small plastic cover or cap on the outside edge of the mirror housing. Carefully remove this cover, if present, with a screwdriver or your trim tool. You might find 1-2 screws.
3. Remove the Screws: Carefully remove the screws holding the mirror housing to the door.
4. Disconnect the Electrical Connector (if applicable): Heated mirrors and power-adjustable mirrors have an electrical connector. Carefully disconnect this connector. Sometimes a gentle tug is sufficient; other times a small release tab needs to be pressed.
5. Remove the Mirror Assembly: Once the screws are removed and the electrical connector is disconnected (if any), gently pull the mirror assembly away from the door. It may be slightly snug, but should come free.
6. Install the New Mirror: Align the new mirror with the mounting points on the door. Attach the electrical connector (if applicable). Secure the mirror housing to the door with the screws.
7. Replace Cover (if applicable): Reattach the plastic cover over the screws.
8. Reconnect Battery Terminal: Reconnect the negative battery terminal.
9. Test: Test the mirror functionality (power adjust, heating, etc.) to ensure everything works correctly.
Important Considerations:
* Glass Replacement: If only the glass is broken, replacing the entire assembly is often more cost-effective than just replacing the glass. However, some aftermarket glass replacements might be available.
* Manual vs. Power: The process is slightly simpler for manual mirrors without power adjustments or heating elements.
* Variations: The precise location of screws and the design of the mirror assembly can vary slightly between model years and trim levels. Refer to a repair manual or online resources specific to your exact 2000 Chevy Astro. A picture search for "2000 Chevy Astro side mirror removal" might also be very helpful.
If you're uncomfortable performing this repair yourself, take your Astro to a qualified mechanic or auto body shop. They have the experience and the right tools to complete the job quickly and correctly.
