Mounted to the brake pedal arm you will find a small switch. It'll have two wires running to it. These are adjustable and sometimes just need to be adjusted. Otherwise, replace it. They are extremely cheap at any parts store.
Probably the wrong bulbs or the brake lights are getting stuck "on". Or maybe a combination of the two. Check that you have the right bulbs and check to make sure something isn't keeping the brake lights on. FriPilot
Sounds like the brake light switch is defective or out of adjustment. You can find it on top of the brake pedal, usually with 2 wires running to it.
check for bad switch under dash above pedal arm, generally fail after 75,000 miles
check the connection there was a corrosion in the connection of my firebird that was stoping all of the bulbs to work and check the ground on the bulbs if that don't work i would have to say start tracing the wires under the carpet for bad wires but dielectric grese is the tail lights best freind after you get them working. Good luck
To replace the brake light on a 2000 Pontiac Montana open the trunk to reveal the housing units. Find the lights and pull the bulbs out. Replace the units.
You need new bulbs
on some cars the tail lights and brake lights are totally different bulbs gain access to the bulbs and have someone push the brakes so that you can determine which bulbs are the brake lights and replace the tail lights
AnswerThe bulbs for the brake lights are usually separate from the normal tail light bulbs. Check and replace the brake bulbs first, and if they are still not working examine the fuses, switch and wiring.
