My 2002 S has brake lights stay stuck on when ignition on, and at the same time the cruise control doesn't work, cc light blinks. Tried the search but people don't have both happen together. I wonder if I should change the brake light switch

 

Sounds like a good place to start. Possible general module as well

 

On my 2006 the brake switch is mounted in a ajustable mount. Mine has moved a couple times and caused the same kind of problems

 

The problem is fixed with a new brake light switch. (The part is $72 out the door at dealer omg , so I bought a used one from a part-out.)
After the brake light problem was fixed, the cruise control still wouldn't activate; however, it fixed by itself all of a sudden after two days.
