General Steps (Expect Variations):
1. Prepare the Vehicle: Park on a level surface, engage the parking brake, and disconnect the negative battery terminal to prevent electrical shocks.
2. Interior Access: You'll likely need to access the light from the inside of the car. This usually involves removing the interior trim panel above the rear window. This may involve unscrewing fasteners and carefully prying clips to release the panel without breaking them. The repair manual will show you exactly which panels and fasteners to remove.
3. Exterior Access (Possibly): Depending on the design, you *might* need to remove the rear hatch or even parts of the rear body panel to reach the light assembly from the outside. This is less likely but possible on some models and years. Again, check your repair manual.
4. Disconnect Electrical Connectors: Once you've accessed the brake light assembly, carefully disconnect the electrical connectors. Take pictures or make notes on how the wires are connected to avoid confusion during reassembly.
5. Remove the Brake Light Assembly: This usually involves unscrewing fasteners that hold the light assembly in place. Be gentle to avoid breaking any fragile plastic parts.
6. Replace the Bulb (or Assembly): The 1988 Corvette likely uses a standard bulb or a small assembly. Replace the faulty component with a new one matching the original specifications (voltage and wattage).
7. Reassembly: Carefully reverse the removal steps. Make sure all electrical connectors are securely connected, and all interior panels are properly reinstalled. Double-check the screws and clips.
8. Reconnect the Battery: Reconnect the negative battery terminal.
9. Test: Test the third brake light to ensure it's working correctly.
Important Considerations:
* Repair Manual: A genuine Chevrolet repair manual for your specific year and model is invaluable. It will provide precise instructions and diagrams that are crucial for avoiding damage.
* Tools: You'll likely need various tools such as screwdrivers (Phillips and possibly flathead), trim removal tools (plastic pry tools are ideal to avoid scratching the interior), and possibly sockets or wrenches.
* Patience: This is not a five-minute job. Take your time and work carefully to avoid damaging the interior or the light assembly.
* Safety First: Always disconnect the negative battery terminal before working with any electrical components.
Without a repair manual specific to your 1988 Corvette, attempting this repair could lead to frustration and potential damage. Invest in the manual – it's worth it.
