The 1955 Chevy, a classic beauty, sometimes comes with classic quirks, especially when it comes to the brake light warning switch. This switch plays a crucial role in your safety, alerting other drivers when you’re braking. If your brake lights aren’t working correctly, it could be due to a faulty brake light warning switch. This article will guide you through understanding the switch’s function, common issues, and how to troubleshoot them, ensuring your classic Chevy stays safe and roadworthy.
Understanding the 1955 Chevy Brake Light Warning Switch
Before we delve into troubleshooting, it’s essential to understand what the brake light warning switch does. In your 1955 Chevy, this switch serves two primary functions:
- Activating Brake Lights: When you press the brake pedal, the switch closes a circuit, allowing electricity to flow to the brake lights, signaling to other drivers that you are slowing down.
- Warning Light Illumination: In a dual-function switch, a separate circuit is completed when the brake pedal is pressed, illuminating a warning light on the dashboard. This light serves as an indicator of a potential issue with your braking system.

Common Issues with the 1955 Chevy Brake Light Warning Switch
Several issues can arise with the brake light warning switch in your 1955 Chevy. Recognizing these common problems is the first step towards a solution:
- Brake Lights Not Working: If your brake lights aren’t illuminating when you press the pedal, it could indicate a faulty switch that’s failing to close the circuit.
- Brake Lights Stay On: Conversely, if your brake lights remain constantly lit, the switch might be stuck in the closed position, continuously sending power to the lights.
- Warning Light Malfunction: If the dashboard warning light doesn’t illuminate when the brake pedal is pressed, the switch’s second circuit might be faulty.
Troubleshooting Your 1955 Chevy Brake Light Warning Switch
Now that you have a basic understanding of the switch and its potential issues, let’s dive into some troubleshooting steps:
- Check the Fuses: Begin by inspecting your 1955 Chevy’s fuse box. Locate the fuse associated with the brake lights and the warning light circuit. If a fuse is blown, replace it with a new one of the correct amperage.
- Inspect the Wiring: Carefully examine the wiring connected to the brake light warning switch. Look for any signs of damage, such as fraying, burning, or loose connections. Repair or replace any damaged wiring as needed.

Test the Switch: With the ignition off, use a multimeter to test the switch’s continuity. Connect the multimeter leads to the switch’s terminals. Press the brake pedal and observe the multimeter reading.
- If the multimeter shows continuity only when the pedal is pressed, the switch is likely functioning correctly.
- If there’s no continuity or continuity even without pressing the pedal, the switch likely needs replacement.
-
Adjust Switch Position: In some cases, the brake light warning switch might simply be misaligned. This misalignment can prevent the switch from being activated correctly by the brake pedal. Try adjusting the switch’s position slightly.
Replacing the Brake Light Warning Switch
If your troubleshooting leads you to believe that the switch is faulty, replacing it is a relatively straightforward process:
- Disconnect the Battery: For safety, always disconnect the negative battery cable before working on any electrical components.
- Locate and Remove the Switch: The brake light warning switch is usually located under the dashboard, near the brake pedal mechanism. Unscrew and carefully disconnect the electrical connector and the switch.
- Install the New Switch: Install the new switch in reverse order, ensuring the electrical connections are secure.
- Test the System: Reconnect the battery and test the brake lights and warning light to confirm that the new switch is functioning correctly.
