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.
Check the switch on the brake pedal
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.)
brake switch ???
On a 1994 Buick LaSabre why does the engine continue to rev up while driving even when the brake is applied ? or when driving why doesn't the engine return to idle when the brake is applied? I would check for a vacuum leak
I am having the same trouble. My brake lights work with the light switch for nighttime driving, but only far right brake light works when i pres brake pedal. Reverse lights dont work at all. Turn signals and hazard light work.
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
Most likely no brake lights would be due to a faulty switch on the brake pedal or a bad fuse.
Blown fuse or bad brake light switch?
I would first check your brake light switch which is attached to your brake pedal under the dash. Since you can turn off the lights by pushing the pedal it is possible the switch is bad. They are around $10.00.I hope this helps you. Mark
It can lead to an accident
brake light switch would be most common cause
The BOO (Brake On/Off) Switch may need to be replaced. If it is bad, it would cause the brake lights to NOT illuminate when the brake pedal is applied.
check the fuse for the brake lights, they have thier own. also check the brake light switch at the at the top of the brake petal
BAD BRAKE LIGHT SWITCH AT TOP OF BRAKE PEDAL
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.
The bulb is burnt out. If the problem was a fuse, then all brake lights and probably the dashboard lights would be out as well.
Possible ground issue at the taillights.
Those tail lights could be the brake lights you are seeing and that would be a faulty brake light switch or the brake light switch is out of adjustment.
The bulbs are burnt out.
Check the switch that is on the break pedal,,,,some times got stock or wire is between the pedal and the switch making pressure on the bottom that the pedal push or relies
check the brake light switch that is on top of your brake pedal under the dash, could be out of adjustment or bad.
If you mean the brake lights are stuck on, then check the stoplight switch located on the top of the brake pedal.
it would be the brake light switch about 20 dollars at autozone
