My front flashers turn signals and brake lights dont work. I have replaced the bulbs and checked the fuses. What could cause these
Good morning! Having a electrical issue with several lights. My brake lights,front flashers,and turn signals inside and outside the car do not work. Fuses and bulbs have been replaced. My tail lights work. I have been advised could be a flasher signal relay or the brake light switch or the turn signal switch. All three lights seem to be connected under the same bulbs and circuits for my car. Is there a specific part that needs to be replaced that would incorporate all three situations?
My car has 143000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
The different lights all go through the turn signal light turn switch. If the brake light switch is not working at all then the third brake light would not work. You will need to replace turn signal switch and check brake light switch also and replace it if no third brake light is working.

Chances are, if your brake and turn signals have all gone down, your fuse is as good as gone. You can find your car`s fuses in the fuse box, often underneath the hook or on the kick panel inside the passenger compartment. Your car manual should tell you which fuse is for your brake circuit.
Like all of the lights on and in a vehicle, turn signals rely on a fuse. When the fuse blows, electric power to the turn signals will be shut off entirely. Burnt out bulbs: As with all light bulbs, turn signal lights can burn out and die.
A faulty switch can be one of the main reasons why the turn signals don`t work. It is also good to check the parking lights, which usually utilize the turn signal bulbs. If the parking lights and hazards come on, but that side doesn`t illuminate when you hit the switch, then it`s a circuit problem.
When we use the turn signal switch, it cancels the brake light signal, on the side selected. If it did not, the lights would stay on and not flash. A bad turn-signal switch may interrupt the brake light circuit when it should not. A broken wire to or from the switch may also cause the lower brake-lights not to work.
And because the taillights and brake lights do not share the same circuit, confirming the ground as a potential cause is not a task that needs much analysis.
It is a 15amp fuse that powers the stop light switch on the brake pedal. The brake light switch sends power to rear brake lights.
It is usually located under the driver`s side of the dash, and is wired in-line with the turn signal lever and hazard switch buttons.
Bulbs in need of replacement – Like any other bulb, indicator bulbs have a finite life and will eventually need replacement. Indicator bulbs can often blow from old age, excess vibration or a faulty regulator in the alternator that causes high car battery voltages and over charging of the cars battery.
Hazard lights and turn signals use the same bulb, so it is not the bulb, the lamp, or the cables to them. Turn signals only work when the ignition is on; hazard lights work whether the ignition is on or not. The two systems have separate power supplies, so they have separate fuses. You may have a blown fuse.
A brake light switch is an electrical switch that turns your brake lights on when you hit the brakes. It`s an integral part of your braking system and lets the driver behind you know that you`re slowing down. It also has a direct influence on your ABS, cruise control system, and more.
A blown fuse. If the bulb or socket isn`t the problem, the next check is the fuse or the light switch. Fuses for everything electrical, including your tail lights, are always found in the fuse box. They are usually located under the hood or in the cabin.
Check the fuse.
A blown fuse usually causes both lights to go out. On newer cars, the tail lamps can be fused separately and/or each bulb or shared circuit can be fused. A fuse can be blown due to other problems, so you`ll need to check more than just the fuse, but it`s the right place to start.
The Light Control Module (LCM) is an important component of a vehicle because it controls all of the car`s lights, as well as the horn function.
Like all fuses, the brake light system fuse can be found in the power distribution center, which is under the dashboard or tucked away underneath the hood. Never heard of the power distribution center? It`s just the technical name for a fuse box.
You only need a Brake-Lite Relay if you`re installing a supplemental towed vehicle braking system that pushes or pulls the brake pedal. With the engine off, step on your brakes. If the brake lights do not illuminate, you do not need a Brake-lite Relay.
Our two pin flasher relay is truly universal! Suitable for 6V or 12V systems and fully functional with LED or standard incandescent bulbs.
Check for a blown circuit fuse. Verify that circuit connections are not loose, corroded, or unplugged. Inspect the wiring harness or terminals for the rear section of the circuit. Check for a bad connection between the turn signal switch and the flasher or between the flasher and the ignition switch.
Reasons Why Tail Lights not Working When Brake Lights are:
Faulty fuse—when troubleshooting this issue, the first piece of professional advice you`ll usually receive is to check the tail light fuse. Often, a bad fuse is to blame. Wiring—once again, wiring issues are key to pinpointing this problem.

In many newer cars there is one light bulb per tail light. There are two filaments in each light bulb. One is for your brake light and one is for your turn signal.
The most common reasons your brake light is on: The Parking Brake is engaged. Brake Fluid is low or leaking. Worn brake pads.

My front flashers turn signals and brake lights dont work. I have replaced the bulbs and checked the fuses. What could cause these
ANSWER : The different lights all go through the turn signal light turn switch. If the brake light switch is not working at all then the third brake light would not work. You will need to replace turn signal switch and check brake light switch also and replace it if no third brake light is working.
Okay so when I turn my lights on at night my brake lights do not work, when I don’t have my lights on they work fine.
ANSWER : Hi there. Based on your inquiry, it’s highly probable that you have a damaged light switch or some electrical fault inside the turn signal relay. However, it’s also possible that the brake switch above the brake pedal could also be the source of your problem. Due to the fact that multiple electrical components might be causing this issue, it’s a smart idea to first have a professional mobile mechanic complete a brake lights are not working inspection, so they can determine what’s causing all of these issues and recommend the right repairs.
EPC light on 2004 Jetta. Code said brake switch faulty, but brakes lights worked. Replaced brake switch, now no brake lights.
ANSWER : Hi there. The first thing that pops in my mind beyond of what you have listed is perhaps the electrical harness attached to the brake switch. Perhaps the harness itself is damaged or you have an exposed wire, loose ground wire somewhere. You might want to have a professional mobile mechanic come to your location and complete a brake lights not working inspection to help you diagnose this issue.
Turn Signal, cruise, brakes, and emergency flashers not working properly.
ANSWER : If you have already replaced the flasher module for the turn signals, your problem may be in the switch assembly whether it is a shorted circuit or the contacts in the switch not making a proper connection and causing problems with other circuits. The problem with the brake lights and cruise control may be the brake light switch on the brake pedal. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer look at your lighting concerns and offer a more personal diagnosis.
Brake lights are not working. replaced brake light swtch still no brake lights. the third brake light the connection was melted at
ANSWER : The first thing to do is to repair third brake light and replace the brake light fuse and then see if the third brake lights work and the lower lights start working? If only the 3rd brake light starts working then you may need a further checks on the turn signal flasher or switch could be bad.
Van keeps blowing fuses, no lights in back work, can’t shift unless key is in certain position
ANSWER : There is a short somewhere, causing the fuse to blown continuously. In your vehicle, power flows from the ignition switch to the transmission range sensor. This sensor needs to be operation in order for the transmission to be moved out of park, as does the ignition switch. Since your headlights always stay on, there is obviously a short somewhere in that circuit. This kind of problem will require firsthand professional diagnosis from a professional. I recommend calling YourMechanic to diagnose and repair this electrical problem since we come to your home or office.
Just replaced head gasket, changed crack sensor new plugs. The check engine light is on, but dim, the only other light that the dash is a normal battery indicator. The fuel pump is not running when switch is turned on, the power windows don’t work, it turns over but not firing. It’s like only one part of the system is working. Also the heater fans work even if the switch is off.
ANSWER : I would first look at the diagnostic trouble codes. Those codes are available because the check engine light is on. If the fuel pump is not running (momentarily) at key on, that fault alone will prevent the car from starting as there will be no fuel pressure. Pump output and pressure can be directly tested and you can also check for electrical power to the pump. To find out why the engine will not run, the recommended diagnostic is a no start diagnostic. If you request that service, the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
My rear left turn signal will not work and I have replaced the bulb and checked the fuse.
ANSWER : Hey there. The most likely problem is the bulb holder / socket itself. It may look fine but probably has a crack or break internally. Also possible (but rare) is the circuit board within the tail lamp housing itself. I recommend having a qualified professional, like one from YourMechanic, inspect the lights in person in order to have this corrected properly.
