Tools You'll Need:
* Phillips head screwdriver: This is most likely what you'll need to remove the light assembly.
* New brake light bulb: Make sure you get the correct bulb type. Your owner's manual should specify the correct bulb number (often a 3157 or 1157, but it's best to verify). Auto parts stores can help you find the correct one.
* Gloves (optional): To keep your hands clean.
Steps:
1. Locate the Bulb: Open the tailgate or rear door. The brake light assembly is located in the taillight housing.
2. Access the Light Assembly: There are usually a few screws securing the taillight assembly to the vehicle's body. These are typically located either on the inside of the tailgate/door or along the edges of the taillight housing itself. Use your Phillips head screwdriver to carefully remove these screws. Be gentle to avoid stripping the screws.
3. Remove the Taillight Assembly: Once the screws are removed, gently pull the taillight assembly outward. There might be some clips holding it in place; be careful not to break them. Sometimes there's a small tab or release mechanism you'll need to work with.
4. Locate the Brake Light Bulb: The brake light bulb will be one of the larger bulbs in the assembly. It's usually a dual-filament bulb (one filament for brake lights, one for running lights). You might need to disconnect a wire connector to fully access the bulb.
5. Remove the Old Bulb: Gently twist the bulb counter-clockwise to remove it from its socket. Sometimes, there's a retaining clip, so look closely before forcing it.
6. Install the New Bulb: Insert the new bulb, twisting it clockwise until it's securely in the socket.
7. Reassemble: Carefully reattach the taillight assembly, making sure it's securely snapped into place and all the screws are tightened.
8. Test the Lights: Close the tailgate/door and test the brake lights to make sure they are working correctly. Make sure to test both the brake lights and the running lights. If one isn't working, you may have the wrong bulb or a wiring issue.
Important Considerations:
* Consult Your Owner's Manual: Your owner's manual should have diagrams and instructions specific to your 1998 Chevy Tahoe. This is the best resource.
* Bulb Type: Double-check the bulb type before purchasing a replacement.
* Wiring: If you encounter any wiring issues, it's best to consult a professional mechanic.
* Safety: Always exercise caution when working with vehicle components.
If you're uncomfortable performing this repair yourself, it's always best to take your vehicle to a qualified mechanic. They have the experience and tools to do the job safely and efficiently.
