Brake lights

Hey all, I'm new here and have a question/plea for help! I just bought a 96 Aurora, that works great with just a few maint. issues, but my main problem is my brake lights don't work! The cyclops works fine, I replaced the bulbs, turn signals work and emergency lights work so I'm stumped. A friend who owns a 98 Aurora said that he had trouble with his turn signals and it cost him over $600 to fix so I'm a little worried. Thanks in advance

My mom's car had the same exact problem. It ended up being the switch at the brake pedal that was bad in her case.

Thanks I'll look into it!
