1. Preparation:
* Park safely: Ensure your Tahoe is parked on a level surface and the parking brake is engaged.
* Gather tools: You'll likely need a Phillips head screwdriver (possibly a trim tool or panel pry if it's really snug). A flashlight can be helpful.
2. Accessing the Taillight:
* Interior access (likely the easiest): Open the rear hatch or door (depending on which side you're working on). There's typically an access panel inside the cargo area (or sometimes even the trunk side panel) partially or fully covering the back of the taillight assembly. This panel is usually held in place with a few screws or plastic clips. Carefully remove these. Some panel tools make this easier than a screwdriver, preventing scratching.
3. Removing the Taillight:
* Inside access continued: Once the access panel is off, you should see the back of the taillight assembly. There will be screws holding the taillight assembly in place. Remove these screws. The taillight may then pull straight out or might require some gentle persuasion. Be mindful of any wires connected to the assembly.
* Outside access (less common, may require more disassembly): In some rare cases, you might *also* need to remove interior trim pieces from the outside of the vehicle (like the side panel of the hatch) to reach the taillight screws. This is less likely, but check for any screws on the outside around the taillight before resorting to this.
4. Disconnecting the Electrical Connector:
* After removing the screws, you'll need to disconnect the electrical connector from the back of the taillight assembly. Gently push or pull the connector tab to release the connection.
5. Removing the Taillight (continued):
* Carefully pull the taillight assembly away from the vehicle. There might be some clips or friction holding it in, so be gentle to avoid breaking any plastic clips.
Important Notes:
* Be gentle: Plastic parts can easily break. Use caution when prying or pulling.
* Take pictures: Before you start, take pictures of how everything is connected so you can easily put it back together.
* Consult a repair manual: A repair manual specific to your 1999 Chevy Tahoe will give you the most accurate and detailed instructions. Online manuals can sometimes be found, though their quality varies.
* Wiring: Be careful not to damage the wiring harness when removing and reinstalling the taillight.
If you're uncomfortable working on your car, it's always best to take it to a qualified mechanic. They will have the proper tools and expertise to avoid causing any damage.
