Brake lights stay on and when brakes are pressed it goes off. I had to take battery off. Wires come hot.
Make sure its not low brake fluid or next check to see if brake pads are not worn low( this switch may be stuck on a caliber) also a failing alternator will make all the lights come on and drain your battery.( shorting Diodes)

Normally this is caused by a problem with the brake light switch. If you don't take care of this soon you will have a dead battery, so try this. Look under the dash at the brake pedal. There will be a switch mounted on the backside of the pedal/arm that has a push button switch inside. Have someone stand behind the car and check to see if the brake lights go off when you pull the brake pedal away from the switch toward the driver's seat. If they do, then you need to turn the outer housing of the switch a little bit to make it pull away from the brake pedal when the pedal is in its resting position.
Sorry, I can't remember which way to tell you to turn it but a few turns should be all that it takes. If that doesn't work then you may need to replace the switch but they rarely fail.

It could be the relay, which is a yellow box located under the carpeting in the trunk on the left side. It is a problem common to your model. Also, check the brake switch's (behind the brake pedal) functionality (12V present with key at ACC or ON and continuity between wires when button engaged).
i hope this helps
