Sounds like you've been doing some guessing! You need to find where the power stops. Use a test light at the sockets. If no power, go to the wire to the socket. When you find where power goes in but doesn't come out, you have your answer. Assuming there is one answer. There is also a possibility of a ground problem. Good luck. If it uses the same bulbs for brake lights and rear turn signal lights, it's possible that the turn signal switch is faulty. On these designs, the brake light circuit runs through the turn signal switch so that when you turn, the brake light for that side is disconnected, allowing the bulb on that side to blink (otherwise the bulb would stay on steady for the brake light function).
Check all the fuses. If not bulbs or switch that's all that it can be,
it could be your brake light switch,or the fuse could be blown ,or the bulbs could be blown.or it could also be the turn signal switch.
it maybe the brake switch
Your problem may be with any or all of these three items: The fuse, brake switch or bulbs in the brake lights.
Check the bulbs. If these are OK it could be the switch on the brake pedal arm.
Could be, a blown fuse, burned out bulbs, bad brake light switch, or an improperly installed brake light switch.
Brake pedal switch, wiring, bulbs, bad trailer harness (if there), fuses...
They are two separate circuits, each has their own fuse. The brake lights not working could be caused by a few things such as a blown fuse, blown bulbs, bad brake light switch, misadjusted brake light switch and depending on what vehicle you have, a bad signal light switch.
It could be the ground wire, the brake light switch, a damaged wire or connector or the turn signal switch.
It could be the brake light switch, usually mounted on the brake pedal.
It could be the brake light switch (the switch that activates the brake lights when you step on the brake pedal) has gone bad
What year is the Ford Explorer ? There could be a separate fuse for the lower brake lights
Bulbs? Sockets? Steering column switch?
Check the switch that is attached to the brake pedal. There are at least two possibilities that come to mind. 1) You could have broken or frayed wires leading to the brake lights, which are preventing current from getting to the bulbs. 2) The brake light switch, (located under the dash, by the brake pedal assembly) may be bad. When you step on the brake, the lever the pedal is attached to pushes a small switch, which sends current to the brake lights. Hope this helps.
First you need to determine the cause. It could be blown bulbs, blown fuse, out of adjustment brake light switch, bad brake light switch, damaged wiring, loose or bad grounds, etc.Most times, when your break lights are not working the bulbs need to be changed. You need to change the bulbs through the opening in the back of your trunk.
Bulbs , Flasher under dash, broken wiring
A defective brake light switch could cause the problem. Also a defective turn signal switch could also. The brake lights work through the turn signals. It cancels the brake light so that the turn signal can work.
The switch could be bad or the wire could be burned out.
Have an electrician check the wiring that goes to the brake lights in the trunk of the car.
a crappy car. my 99 beetle has the same problem. brake light switch new, bulbs and fuses new. brake lights just work whenever the heck they want. this is one of the many reasons my car has a for sale sign in the window. good luck.
If the turn signal is working it's either the brake light switch or the turn signal switch.
First check the bulbs. If they are good then the switch that is connected to the brake pedal could have gone bad. Hope this helps.
Likely to be the brake light switch on the pedal at fault if the bulbs and fuses are good and other lights work ok.
id cheack your brake light switch. its rightbehine your brake peddle it could be that malfunction, its a chap part to change $15 or less but u could also check your fuses if the bulbs are still good due to the bulbs having 2 separate filiments one for runin light and for brake..
Because something's wrong, of course. What it could be... bad switch, break/short in the wiring, bad fuse or relay, or even just bad bulbs.. chances are, your car uses dual filament bulbs for the brake lights, where they'll function as both marker lights (with one filament active) and brake lights (with both filaments energized).
