how do I change the brake pedal switch on a 2008 chevy cobalt?

Hello, To find the brake light switch, you'll need to lay on your back in the floorboard, shine a flashlight up, and maybe remove the trim panel where the driver knees are. These are always a pain to get to because they are tucked between the firewall and the very top of the brake pedal, but removal and installation are easy once you view how it is installed.
