1. Open the Trunk: Access the trunk of your Caprice.
2. Locate the Brake Light Assembly: The third brake light is located in the rear window, usually at the top of the trunk lid. You should see a trim piece or panel surrounding the light.
3. Remove the Trim: This is usually the most challenging part. The method varies slightly depending on the exact Caprice model and any prior repairs or modifications. It might involve:
* Push-pins: Carefully pry off small plastic push-pins or clips holding the trim in place. Use a flat, blunt instrument (like a plastic trim tool) to avoid scratching the paint. Work slowly and systematically to avoid breaking the clips.
* Screws: Some models may use screws, which you'll need a screwdriver to remove.
4. Disconnect the Electrical Connector: Once the trim is removed, you should see the brake light bulb housing. Carefully disconnect the electrical connector from the bulb socket. It usually just pulls straight off, but be gentle to avoid damage.
5. Remove the Bulb: The bulb itself is usually a wedge-base bulb (often called a wedge socket bulb) that should simply pull straight out. If it's stuck, gently wiggle it back and forth while pulling.
6. Install the New Bulb: Insert the new bulb of the correct type and wattage (check your owner's manual for the specific bulb type). Push it firmly until it clicks into place.
7. Reconnect the Electrical Connector: Carefully reconnect the electrical connector to the bulb socket, making sure it's securely attached.
8. Reinstall the Trim: Carefully reinstall the trim piece, making sure all the clips or screws are properly secured.
9. Test the Brake Light: Close the trunk and test the brake light to ensure it's working correctly.
Important Notes:
* Bulb Type: Before starting, find the correct replacement bulb type for your Caprice. Your owner's manual or a parts store can help you identify this.
* Safety: Always disconnect the electrical connector before handling the bulb to prevent accidental shocks.
* Patience: Removing and reinstalling the trim can be tricky. Take your time and be gentle to avoid breaking any clips or damaging the surrounding area.
* If Unsure: If you're uncomfortable performing this repair yourself, it's best to take your Caprice to a qualified mechanic.
This guide provides a general overview. The exact steps may vary depending on the specific trim level and condition of your 1989 Chevrolet Caprice. Always prioritize safety and consult your owner's manual for the most accurate information.
