Your best approach is to consult your owner's manual. It will have a fuse box diagram showing the location of the fuse box (or boxes – some Camaros have multiple) and a legend showing which fuses control what circuits. Look for fuses related to the tail lights, stop lamps, or possibly even the brake light switch. Note that sometimes a blown fuse is a *symptom* of a larger problem.
Troubleshooting Steps (in order):
1. Check the Brake Light Switch: This is a common culprit. It's located on the brake pedal assembly and is easily accessible. You can test it with a multimeter to see if it's providing power when the brake is depressed. A simple visual inspection for obvious damage is also a good first step.
2. Check the Bulbs: Before assuming a blown fuse, visually inspect the brake light bulbs themselves. They may simply be burned out.
3. Check the Fuses: Using your owner's manual, systematically check all fuses related to the tail lights and brake lamps. Many Camaros have a fuse box under the hood and another inside the car, usually near the steering column.
4. Check the Wiring: If fuses and bulbs are fine, there might be a break or short in the wiring to the taillights. This is more involved and might require tracing the wires.
5. Consult a Mechanic: If you're not comfortable with electrical work, it's best to take your Camaro to a qualified mechanic to diagnose and repair the problem. Incorrectly working on your car's electrical system can cause further damage.
