Tools you'll likely need:
* Phillips head screwdriver (possibly a socket wrench as well depending on the screw type)
* New brake light bulbs (check your owner's manual for the correct wattage and type)
* Optional: Gloves to protect your hands from grease
Steps:
1. Safety First: Park your car on a level surface, engage the parking brake, and turn off the ignition.
2. Access the Taillight Assembly: You'll need to access the taillight housing from the trunk. Open the trunk. Typically, there are screws or clips holding the taillight assembly in place. You might need to remove interior trim panels or coverings to reach them. Examine the area around the taillight closely to locate these fasteners.
3. Remove the Taillight Assembly: Once the screws or clips are removed, gently pull the taillight assembly outward. It might be slightly snug, but avoid excessive force to prevent breakage.
4. Locate the Brake Light Bulb: Inside the taillight assembly, you'll see several bulbs. Identify the brake light bulb(s). They are usually larger than the turn signal or running light bulbs. Your owner's manual or a diagram on the inside of the trunk lid may show the bulb locations.
5. Remove the Old Bulb: Carefully twist the old brake light bulb counterclockwise to remove it from its socket. Be careful not to touch the glass part of the bulb as the oils from your fingers can shorten its lifespan.
6. Install the New Bulb: Insert the new brake light bulb into the socket, and twist it clockwise until it's securely fastened. Ensure it's properly seated.
7. Reassemble: Carefully put the taillight assembly back into place, making sure it's aligned correctly before fastening the screws or clips.
8. Test the Brake Lights: Turn on your car's ignition and then press the brake pedal. Check to make sure the new brake lights are working correctly. If not, double-check the bulb's installation and the connection.
Important Notes:
* Different bulb types: The 1998 Buick Century may use different types of bulbs (incandescent, LED). Buy replacement bulbs matching the original type.
* Multiple bulbs: The brake light function might be shared across multiple bulbs in the taillight assembly. Replace all bulbs that are part of the brake light circuit if they are old or burned out, even if only one seems bad.
* If you're uncomfortable: If you're not comfortable performing this task yourself, take your car to a qualified mechanic.
Remember, this is a general guide. Always refer to your owner's manual for specific instructions tailored to your 1998 Buick Century model. Pictures or diagrams in the manual will be invaluable in this process.
