1. Preparation:
* Gather tools: You'll likely need a trim panel removal tool (plastic pry tool is ideal to avoid scratching), a Phillips head screwdriver (possibly a Torx screwdriver depending on the model), and possibly a 10mm socket and ratchet (for some models). Have a clean rag handy to avoid scratching the paint.
* Safety first: Park your car on a level surface, engage the parking brake, and turn off the engine. Consider wearing safety glasses to protect your eyes from any broken plastic or glass fragments.
2. Remove the mirror housing:
* Locate the mirror housing: The mirror is usually attached to a plastic housing that's bolted to the door.
* Remove the trim panel (if necessary): Some Buick Centuries have a small trim piece around the mirror base. Carefully pry this off using your trim removal tool, starting at one corner and working your way around. Be gentle to avoid breaking the plastic clips.
* Locate and disconnect the electrical connector (if applicable): If you have a power-folding or heated mirror, there will be an electrical connector. Carefully unplug it. Some connectors have a release tab or latch; you might need to gently push or pull on the connector to release it.
* Remove the mounting bolts: Look for screws or bolts attaching the mirror housing to the door. These are usually located either behind the mirror housing itself or beneath the trim panel. Unscrew them carefully. Take note of their position and length before removing them.
* Remove the mirror housing: Once the bolts are removed, carefully pull the mirror housing away from the door. It may be attached with clips as well, so gently work it loose. Don't force it; if it's stuck, check for additional clips or fasteners.
3. Replace the mirror glass (if necessary):
* If only the glass is broken: Some mirrors have glass that can be replaced separately. This usually involves removing a clip or retainer holding the glass in place. Consult a repair manual or online video specific to your Buick Century model year for the proper procedure. You'll need a replacement mirror glass.
4. Install the new mirror housing:
* Attach the new mirror housing: Align the new mirror housing with the mounting points on the door.
* Secure the mounting bolts: Reinstall the screws or bolts you removed earlier, tightening them securely.
* Reconnect the electrical connector (if applicable): Plug the electrical connector back into the new mirror housing.
* Reattach the trim panel (if applicable): Carefully snap the trim panel back into place.
5. Test the new mirror:
* Check functionality: If you have a power-folding or heated mirror, test these features to ensure they work correctly.
Important Notes:
* Consult a repair manual: A repair manual specific to your 2002 Buick Century will provide detailed instructions and diagrams, making the process much easier. You can often find these online or at auto parts stores.
* YouTube videos: Search YouTube for "2002 Buick Century side mirror replacement." Visual guides can be incredibly helpful.
* Parts: Ensure you get the correct replacement mirror housing (or mirror glass) for your specific Buick Century model. The auto parts store can help you identify the correct part using your VIN.
If you're not comfortable performing this repair yourself, it's always best to take your car to a qualified mechanic. This is especially true if you have a power-folding or heated mirror, as improper installation could damage the electrical components.
