On a 1996 Chevrolet Suburban, the brake light switch is typically located on the
brake pedal assembly itself. It's a small switch, often cylindrical, that's mounted directly on or near the top of the brake pedal. You'll likely need to look up underneath the dash, above the brake pedal, to find it.
However, the exact location might vary slightly depending on the specific trim level and any modifications. A repair manual specific to your year and model of Suburban would provide the most accurate location.
