To find it, you need to:
1. Consult your owner's manual: This is the most reliable source. It will have a fuse box diagram showing the location of the fuse box(es) and which fuse controls the turn signals (often labeled "turn signals," "flashers," or similar).
2. Check the fuse boxes: Camaros typically have at least one fuse box under the hood and one inside the car, often near the steering column or under the dashboard. Look for a diagram on the inside of the fuse box cover.
Without knowing the year and model of your Camaro, it's impossible to give you a precise location.
