However, here's a general guide covering both:
For the regular brake lights (on the taillights):
1. Safety First: Park on a level surface, engage the parking brake, and turn off the vehicle. Wear safety glasses.
2. Access the Taillight: You'll usually need to access the taillight assembly from inside the cargo area. On most Tahoes, there's an access panel inside the tailgate or liftgate, covered by trim panels. Remove these panels carefully – usually just clips or screws.
3. Disconnect the Electrical Connector: Once you have access to the taillight assembly, carefully disconnect the electrical connector. Gently pull on the connector, not the wires.
4. Remove the Taillight Assembly: Depending on the specific year and trim, this might involve removing screws or carefully prying the assembly out. Again, proceed cautiously to avoid damage.
5. Replace the Bulb: Identify the burned-out bulb (usually the brake light is a separate filament from the taillight). Some Tahoes might use a single bulb with multiple filaments, others might have separate bulbs. Twist the bulb counter-clockwise to remove it.
6. Install the New Bulb: Install the new bulb, ensuring it's securely seated.
7. Reassemble: Reconnect the electrical connector, reinstall the taillight assembly, and replace the trim panels.
8. Test the Lights: Turn on your brake lights and check to make sure the new bulb works.
For the High-Mounted Stop Lamp (CHMSL or Third Brake Light):
1. Access the CHMSL: This usually involves accessing it from inside the vehicle. You'll likely need to remove the interior trim panel covering the CHMSL. This often involves releasing clips or removing screws. Refer to your owner's manual for precise instructions.
2. Remove the Lens: Once you have access, remove the CHMSL lens or cover. This might involve carefully prying it loose, often with a trim tool to avoid scratching.
3. Replace the Bulb: Carefully replace the burned-out bulb. These are often wedge-style bulbs.
4. Reassemble: Reinstall the lens or cover, and put back the interior trim panel.
5. Test the Lights: Check the CHMSL is functioning correctly.
Important Considerations:
* Bulb Type: Ensure you buy the correct type and wattage of bulbs. The owner's manual will specify this.
* Tools: You might need a Phillips head screwdriver, trim panel removal tools, and possibly a small pry tool.
* If Unsure: If you're uncomfortable performing this repair yourself, take your vehicle to a qualified mechanic. Improperly installed lights can be a safety hazard.
Remember, this is a general guide. Always consult your 2005 Chevy Tahoe's owner's manual for the most accurate and detailed instructions specific to your vehicle's model and trim level. Pictures in the manual will be extremely helpful.
