1. Access the Light Assembly:
* Locate the light assembly: It's usually located on the inside of the trunk lid, near the license plate. You'll see a small, usually rectangular or round, housing for the bulb(s).
* Open the trunk. You'll likely need access to the inside of the trunk lid to reach the bulb.
* Remove any access panels: Some models might have a small panel covering the light assembly. This panel might be held on by clips or screws. Carefully check for these and remove them if necessary. Sometimes you can just pry the panel carefully with a small flathead screwdriver.
2. Remove the Bulb:
* Disconnect the electrical connector: Gently unplug the electrical connector from the back of the light assembly. It should simply pull off.
* Remove the bulb: The bulb socket usually twists out (either clockwise or counter-clockwise—try a gentle turn in one direction, and if it doesn't budge, try the other). Be gentle, as the socket is often made of plastic and could break.
* Note the bulb type: Before removing the bulb completely, take note of its type (often written on the bulb itself). This will help you buy the correct replacement. Common types are 168, 194, or similar.
3. Install the New Bulb:
* Insert the new bulb: Carefully insert the new bulb into the socket, making sure it's seated correctly.
* Push and twist: Push the bulb socket back into its place. It should click or snap securely.
* Reconnect the electrical connector: Reattach the electrical connector to the back of the light assembly.
4. Reassemble:
* Replace any access panels: If you removed any access panels, put them back in place and secure them.
5. Test the Light:
* Close the trunk: Close the trunk and make sure the new bulb is working correctly. Check both brake and regular lights if applicable.
Important Considerations:
* Gloves: Wear gloves to avoid getting fingerprints on the new bulb.
* Proper Bulb: Use the correct type of bulb as indicated on the old one or your vehicle's manual. Using the incorrect bulb could damage the socket or the light assembly.
* Gentle Force: Always use gentle force when working with the light assembly and bulb socket. Avoid excessive force, which could cause damage.
* Vehicle Manual: If you're having trouble, consult your Buick Century's owner's manual for specific instructions or diagrams. You can often find this online as well if you have lost your original copy.
If you're still struggling, you can consult a local mechanic or auto parts store for assistance. They may be able to provide more specific guidance for your particular vehicle model.
