1. Preparation:
* Gather tools: You'll likely need a Phillips head screwdriver (possibly a trim tool or panel removal tool for less risk of scratching), and possibly a small flathead screwdriver.
2. Accessing the Tail Light Assembly:
* Interior Access (Most Likely): Most often, the access to the taillight bulbs and the housing is primarily from the inside of the truck's bed. Look for screws securing the taillight assembly from inside the bed. These are usually located behind an access panel, usually held in place by plastic clips or screws. You may need to remove the inner bed liner if you have one.
* Exterior Access (Less Likely but Possible): While less common on this model year, some access might be possible from the exterior. Look very carefully around the edges of the taillight assembly for screws or clips. This is less likely as it's usually more involved to access the lights this way.
3. Removing the Taillight Housing/Bezel:
* Screws: Once you've accessed the back of the taillight, locate and remove any visible screws.
* Clips: After removing screws, carefully pry the taillight assembly away from the body. Use your trim tool or a flathead screwdriver (carefully!) to release any plastic clips holding the assembly in place. Work your way around the perimeter. Don't force anything – if it's not budging, you're likely missing a screw or clip.
* Wiring Harness: Once the clips are released, the taillight assembly should come loose. Carefully disconnect the electrical connector from the back of the taillight. Usually there's a release tab or latch.
Important Considerations:
* Be Gentle: Plastic clips are brittle and can easily break. Work slowly and carefully.
* Consult a Repair Manual: A repair manual specific to your 1997 Chevy S10 will provide detailed, illustrated instructions. This is the best way to avoid damaging your truck. You can usually find these online (e.g., Haynes or Chilton manuals).
* Take Pictures: Before you start, take pictures of how the assembly is attached. This will be invaluable when putting it back together.
If you're uncomfortable working on your vehicle, take it to a qualified mechanic. Attempting repairs without the proper knowledge can cause further damage.
