Is Your Brake Light Switch Failing?
A bad brake light switch can cause some confusing problems. The most obvious sign is when your brake lights don't work at all, or they stay on constantly, which can drain your battery. You might also notice them flickering. In some cases, a faulty switch can prevent you from shifting the car out of park. If your Caprice has cruise control, a bad switch might stop it from working or cause it to turn off unexpectedly.

Driving without working brake lights is extremely dangerous and illegal. If your brake lights are not turning on, you should not drive the vehicle until it is repaired. If they are stuck on, you risk draining your battery and confusing other drivers.
Choosing the Right Aftermarket Switch
For a classic car like the 1980-1987 Caprice, you won't find many new OEM (Original Equipment Manufacturer) parts. Aftermarket parts are your main option. The good news is that for a simple part like a brake light switch, many aftermarket brands offer good quality that meets or exceeds the original specifications.
Aftermarket Brand Tiers
- Premium Aftermarket (Standard Ignition): Standard Motor Products (SMP) is a well-respected brand that has been around for a long time. They are known for making high-quality replacement parts that are reliable and durable. Many professional mechanics trust and use their products. For a critical safety component, choosing a trusted brand like Standard is a smart investment.
- Standard Aftermarket (Rostra Powertrain): Rostra is another established brand that produces a wide range of automotive electronics. Their parts are designed as direct-fit replacements and are 100% tested for performance. They offer a good balance of quality and value.
- Economy Aftermarket (Skyward): Skyward is a budget-friendly option. While likely functional, there is less information available about their long-term reliability compared to more established brands. For a simple part on an older vehicle, it may be a sufficient choice if budget is the primary concern.
Pro Tip: Check Your Connections
Before replacing the switch, always check the basics first. Make sure the brake light bulbs are good and that the fuse isn't blown. Sometimes, the issue is a loose or corroded wire in the steering column or at the taillight sockets, not the switch itself. A simple visual inspection and a circuit tester can save you from buying a part you don't need.

Frequently Asked Questions
Where is the brake light switch located on a 1980-1987 Caprice?
The brake light switch is located up under the dashboard, mounted to the brake pedal support bracket. You will see it attached to the arm of the brake pedal.
Is it hard to replace a brake light switch?
No, it is a relatively easy job for a DIYer. It involves disconnecting the electrical connector, removing the old switch from its bracket, and installing the new one. The most difficult part is the uncomfortable position you have to be in under the dash. The new switch may need a simple adjustment to ensure the lights activate at the correct pedal height.
My brake lights don't work, but the switch is new. What else could it be?
If a new switch doesn't fix the problem, check the brake light fuse first. Also, inspect the bulbs and the sockets for corrosion. On these GM vehicles, the problem can sometimes be in the turn signal switch wiring within the steering column, as the same circuit is used.

Yes, models with cruise control typically use a switch with more electrical terminals (often four). This switch has a second circuit that tells the cruise control system to disengage when you press the brake pedal. Always verify the number of terminals on your old switch before ordering a new one.
