Where is the brake light switch on a 2000 Cadillac Catera?

The brake light switch on a 2000 Cadillac Catera is located on the brake pedal assembly. It's a small switch that's usually mounted on the top or side of the brake pedal itself, often near where the pedal pushes against the brake booster. You'll likely need to look closely and possibly use a flashlight to see it. It's usually a fairly easily accessible location, but you may need to remove some plastic covers or trim pieces to get a better view and access.
