Tools you'll likely need:
* Screwdriver (likely Phillips head)
* Possibly a socket wrench (depending on the type of fastener holding the light assembly)
* New brake light bulb (Make sure you get the correct wattage and type. Check your owner's manual or the old bulb.)
Steps:
1. Safety First: Park your Tahoe on a level surface, engage the parking brake, and turn off the engine. It's a good idea to wear safety glasses.
2. Access the Tail Light Assembly: You'll need to access the rear tail light assembly. This usually involves opening the tailgate or rear hatch. You may need to remove some interior trim panels to reach the light assembly. Look for screws or clips holding the inner panel in place. These are often located around the edges. Gently pry these away with a trim tool (to avoid scratching the plastic) if necessary.
3. Disconnect the Electrical Connector: Once you have access to the tail light assembly, locate the electrical connector plugged into the back of the light unit. Carefully disconnect it by gently squeezing the locking tabs on the connector.
4. Remove the Tail Light Assembly: The tail light assembly is typically held in place by screws or clips. Carefully remove these fasteners. Gently pull the light assembly outward, taking care not to force it.
5. Replace the Bulb: Once the assembly is out, you should be able to access the brake light bulb socket. This usually involves gently twisting the bulb counterclockwise to remove it. Be careful not to touch the glass portion of the new bulb with your bare fingers; the oils from your skin can shorten the bulb's life. Use a clean cloth or tissue to handle the new bulb. Install the new bulb by twisting it clockwise.
6. Reassembly: Carefully reverse the steps above to reinstall the tail light assembly, reconnect the electrical connector, and put any trim panels back in place.
7. Test the Lights: Turn on your brake lights to make sure the new bulb is working correctly. Also, test your turn signals and running lights to ensure nothing was damaged during the process.
Important Considerations:
* Multiple Bulbs: The tail light assembly may contain multiple bulbs for different functions (brake lights, turn signals, running lights, reverse lights). Make sure you replace the *correct* bulb.
* Bulb Types: Tahoe brake lights might use wedge-base bulbs or other types. Refer to your owner's manual or the old bulb for the correct replacement.
* Stuck Fasteners: If any fasteners are stuck, use a penetrating lubricant (like WD-40) and let it sit for a few minutes before attempting to remove them.
* Broken Clips: Be gentle to avoid breaking any plastic clips on the trim or the light assembly. Replacement clips may be available at auto parts stores.
If you're uncomfortable performing this repair yourself, it's always best to take your Tahoe to a qualified mechanic. They have the experience and tools to do the job safely and efficiently.
