The brake light switch on your 95 Silverado is a critical component in ensuring your safety on the road. It is responsible for turning on the brake lights when you press the brake pedal. A faulty brake light switch can lead to unsafe driving conditions, including accidents. In this article, we will guide you through the process of understanding and troubleshooting your 95 Silverado brake light switch wiring diagram.
What is a Brake Light Switch?
A brake light switch is a device that is located under the brake pedal in the car. It is responsible for turning on the brake lights when you press the brake pedal. The switch closes the circuit when the brake pedal is depressed, allowing current to flow and turning on the brake lights. When the brake pedal is released, the switch opens the circuit and the brake lights turn off.
How Does a Brake Light Switch Work?
When you press the brake pedal, the lever moves a plunger in the brake light switch to complete a circuit. The circuit allows current to flow to the brake lights and turn them on. When you release the brake pedal, the spring inside the brake light switch returns the plunger to its original position, opening the circuit and turning off the brake lights.
What are the Symptoms of a Faulty Brake Light Switch?
If your 95 Silverado has a faulty brake light switch, you may experience the following symptoms:
| Symptom | Cause |
|---|---|
| Brake lights not turning on when the brake pedal is depressed | Faulty brake light switch |
| Brake lights not turning off when the brake pedal is released | Faulty brake light switch |
| Brake lights turning on without pressing the brake pedal | Faulty brake light switch |
How to Troubleshoot a Faulty Brake Light Switch?
