I have a 2003 Olds Alero and for some reason my brake lights won't come on when I put on the brakes.

The lights work at night and when I set the alarm, but not when I apply the brakes.

I've changed the bulbs and looked at the wiring and everything looks good there.

What am I missing?

The black box is called the ccrm (constant control relay module) you could check that.
