i found it to be the tail light harnesses go bad . a common problem with them because the bulb sockets short out.
The only way your headlights can come on when you press on the brake pedal is a crossed wire. The brake light wire and the headlight wire can be frayed and touching each other.
you probally need to replace the bulbs
Under the brake pedal is a brake light switch that when you press the pedal it hits it and makes your lights come on..sometimes when they get weak the pedal depresses them simply from the weight of the pedal and they stay on..Have a friend get inside the truck and pull UP on the brake pedal as you look at the lights..if the brake lights go off when they pull up on it..then it is that switch under the brake pedal
just as the name it makes the brake lights come on when u press on the brake pedal
More than likely there is a switch near the top of the brake pedal that is faulty. It usually looks like a small button that is released when you press on the brake pedal which turns on the brake lights.
it's somthing under the brake pedal, it's sticking and just needs to be loosened. you'll also find when you press the pedal in, the brake lights will go off.
put your foot on the brake pedal and press down while some one looks at the brake light to see if it lights up
if you have no brake lights it will most likely be one of 3 things a blown fuse bad ground wire or under the brake pedal you will find a small switch that the pedal hits when you press on the pedal the switch does go bad but is easily replaced and usually not too expensive
Check the fuse, bulbs and actual regulator switch in that order
Adjust or replace the stoplight switch at the upper end of the brake pedal under dash area
You have a poor or no ground between the vehicle and trailer.
It could be a fuse. If the brake lights do not turn on when you press the brake pedal check your fuses under your dash.
you need to get a bigger fuse
Out of adjustment. Adjust the mounting of the switch so the brakes lights are off until you press the brake pedal.
No, on most newer cars you also have to press the brake pedal to shift out of Park.
Most likely it is either the brake light switch, under the dashboard, connected to the brake pedal or the turn signal switch inside the steering column.
when your brake pedal moves up and down when you press the pedal ,usually it is a warped brake rotor or a loose bearing on one or both brake rotors Warped front disk brake rotors.
Check the fuse, and the bulbs, then the switch on the top of the brake pedal
Check the brake light bulbs in back, one of them may installed incorrectly.
Check the bulbs - they are double filamented one filament may be burned out in each bulb It could also be your battery....run it by a car part store; they usually will check the charge of the battery for free.
Your rt side brake light is burned out.
Have someone go in the car and press the pedal and have another look at the side thats working to determine this.
The most common cause for your brake lights staying on is the switch in the foot brake pedal. If it comes loose or is broken. Check the brake pedal assembly, if it has come off it will be hanging about by it's wires or may just be loose. It's a normally closed switch which means it works the opposite way round to a normal switch. IE. ON when not operated and OFF when operated. The brake pedal normally sits against the switch which keeps the circuit open and hence the lights are off. When you press the brake pedal, the switch is released, circuit is closed and the brake lights come on.
You are supposed to only have to press the brake pedal. Evidentally your brake lights aren't working. You probably need to see if the brake light switch is bad.
