Tools you'll likely need:
* Phillips head screwdriver (possibly a trim tool or panel removal tool)
* New brake light bulbs (match the bulb type from your old bulb; check the bulb number on the old bulb itself)
* Gloves (optional, but recommended to keep your hands clean)
Steps (General Procedure):
1. Safety First: Park your Tahoe on a level surface, engage the parking brake, and turn off the ignition. Consider using wheel chocks for extra safety.
2. Access the Taillight Assembly: You'll need to remove the interior trim panel to reach the taillight bulbs. This typically involves:
* Opening the rear liftgate/hatch.
* Carefully removing any interior trim panel covering the taillight. This usually involves prying gently with a trim tool or your fingers, starting at the bottom or edges of the panel. Work your way around, releasing clips. Be gentle to avoid breaking anything. The panel often just clips in. Your owner's manual will provide the best guidance here.
3. Disconnect the Bulb Connector: Once the trim panel is removed, you should have access to the back of the taillight assembly. Locate the electrical connector that plugs into the brake light bulb. Gently disconnect this connector.
4. Remove the Old Bulb: The bulb might be held in by a retaining clip or a twist-and-pull mechanism. Consult your owner's manual for specifics. Once removed, carefully inspect the socket for any damage.
5. Install the New Bulb: Carefully insert the new bulb, making sure it's seated correctly. If there's a retaining clip, ensure it snaps firmly into place.
6. Reconnect the Bulb Connector: Reattach the electrical connector securely.
7. Reassemble: Carefully put back the interior trim panel, making sure all clips are properly engaged.
8. Test the Brake Lights: Turn on your brake lights (lightly press the brake pedal) and check to see if the new bulb is working correctly.
Important Considerations:
* Bulb Type: Make absolutely sure you buy the correct replacement bulb. The wrong bulb type will not fit or will not function properly.
* Fragility: Be gentle when working around the taillight assembly. The plastic can easily crack or break.
* Owner's Manual: Your owner's manual is your best friend for this task. It will have specific diagrams and instructions tailored to your 1999 Chevy Tahoe.
If you're uncomfortable performing this task yourself, it's always best to take your Tahoe to a qualified mechanic. They have the expertise and tools to do the job safely and efficiently.
