Why do I have running lights but no brake lights?
The most common reason your brake lights are not working but tail lights do is a bad light bulb. It can also be caused by a blown fuse, bad brake light switch, or issues with the wirings. Your vehicle’s taillights are working fine, but the brake lights don’t come on when you press the brakes.
How can you tell if a brake light switch is bad?
How do you know if your brake light switch is bad? Here are a few indicators of a bad switch:
- The brake lights don’t work.
- Brake lights don’t go off.
- Cruise control stops working.
- Your car won’t turn on.
- ABS (Anti-lock brake system) warning light comes on.
How do you know if you have a bad brake light switch?
If your brake switch malfunctions, the rear brake lights won’t illuminate, and the driver behind you won’t know that you’re slowing down, causing a major safety hazard. Now, this could indicate that a brake light bulb in the rear has burnt out or that you’ve got a defective brake light switch.
Where is the brake light wiring switch?
In most cars, the brake light switch is installed right above the brake pedal. Inside, it has a one- or two-way electric switch.
What happens when a brake light switch goes bad?
If the switch is bad, the brake lights won’t operate and the transmission shifter will not come out of the “Park” position. In cars with a push-button start system, a faulty brake light switch can cause the vehicle not to start. Often, the brake light switch could be sticking and work intermittently.
How do you test a brake light switch?
Place the sensor on just one of the two wires and hold the brake pedal down as you do so. Then test the other wire. If power is connected and the switch is working properly, the test bulbs will illuminate. If it doesn’t light up, the brake light switch is faulty and will need to be replaced.
