brake switch is bad or maybe the plastic grommet in which the switch is mounted is worn (if this is anything like my 1990 Audi V8). The plastic grommet is a loose fit and allows the switch to self adjust. If it's too worn the switch slides too far forward. First try removing the switch from the grommet(sp?); then remove the grommet. Now you can test the switch and determine whether or not it is the problem. If not, pinch the grommet so the hole tightens then reinstall and reinstall the switch. Now try the pedal. If this doesn't work, replace the grommet with a new one from the dealer.

Why would your tail lights work in your 1996 Silverado Z71 4-wheel but not the brake lights Is it a brake light switch Where's that located?

The brake light switch is under the dashboard, attached to the brake pedal. Try the break pedal, up underneath the dash. This is usually a switch which will open with the lightest pressure on the pedal, which is why some people's brakelights are on all the time. Driving with one foot on the brake pedal means driving with your brake lights on. Which increases the reation time of the the following driver. (End of Sermon.)

If the switch activated by your brake for your 1994 Nissan sentra brake lights and tail lights is broken and your lights stay on when the engine is off how can you fix it?

There is a switch just above the brake pedal that is called the brake stoplight switch. When the brake pedal is released, it stops the brake lights from illuminating. Check to make sure the switch is contacting the brake pedal stop where it should. A short term method of not killing the battery would be to unplug the connector to the switch and get a new one. It won't have brake lights when disconnected so I don't recommend driving with it like that. replace the broken switch

What would make your brake lights not work?

The most likely cause is a bad brake light switch (if none of the brake lights illuminate) but if its only one of the brake lights, try changing the bulb. Even if they still work as running or turn lights because they have a double filament and may still work partially, but not as brake lights.
