Tools You'll Likely Need:
* Phillips head screwdriver (possibly a trim removal tool)
* Possibly a 10mm socket (depending on the bulb connector)
Steps:
1. Prepare the vehicle: Park on a level surface, engage the parking brake, and turn off the engine.
2. Access the Third Brake Light: This usually involves opening the trunk. You'll likely need to remove some interior trim panels to access the brake light assembly. This often involves carefully prying off plastic clips and covers. Be gentle to avoid breaking any clips. Look closely for screws or retaining clips holding the trim pieces in place. Your owner's manual is crucial here as the location and removal procedure vary between trims and model years.
3. Remove the Brake Light Assembly: Once you have access, you'll likely find the brake light assembly itself held in place by clips or screws. Carefully disconnect these fasteners. Some models might have a retaining nut or a push-pin design.
4. Disconnect the Electrical Connector: Once the assembly is loose, carefully disconnect the electrical connector from the back of the light housing. Sometimes a simple push and twist is all it takes to release the connector.
5. Replace the Bulb: Once the light assembly is removed, you can access the bulb(s). If it's a single bulb, simply remove it. If it's a multiple bulb assembly, replace only the burned-out bulb(s). Note the orientation of the bulb before removing it; it may have a specific alignment.
6. Install the New Bulb(s): Insert the new bulb(s), ensuring they're correctly seated.
7. Reassemble Everything: Carefully reverse the steps to reassemble the brake light assembly, electrical connector, and interior trim panels. Make sure everything is securely fastened.
8. Test the Brake Light: Turn on your ignition and apply the brakes. Verify that the third brake light is functioning correctly.
Important Notes:
* Bulb Type: Before you start, determine the correct type of bulb for your 2002 Buick Century's third brake light. You can find this information in your owner's manual or online auto parts store websites using your vehicle's year, make, and model.
* Safety: Avoid touching the bulb's glass with your bare fingers. The oils from your skin can shorten its lifespan. If you do touch it, use a clean cloth or paper towel.
* Professional Help: If you're uncomfortable performing this repair yourself, take your vehicle to a qualified mechanic.
Remember to consult your owner's manual for specific instructions and diagrams. This will significantly reduce the chance of damaging your vehicle's interior.
