1999 Mercury Cougar Brake lights won't turn on

My 1999 Mercury Cougar's brake lights won't work. The reverse, running lights, hazards and signals all work.

I replaced all the bulbs and fuses. Still not working.

I was told about some 'brake light switch' by the brake pedal. Can't find it or maybe I see it but can't tell its a switch? Also, don't know what to look for. Do I turn it? Replace it? Where do I look?

The car is running great and everything is working fine but the brake lights. (Including the small cyclops one on the tail).
