Is Your Lincoln's Brake Light Switch Failing?
A brake light switch is a part that wears out from constant use. On a classic vehicle like the 1976-1981 Lincoln Continental, failure is common due to age. The symptoms are usually straightforward and should be addressed immediately for safety.
Key Failure Symptoms:
🎬 Watch: Understanding Ford brake light switch operation and common problems.- Brake Lights Don't Work: The most dangerous symptom is when your brake lights fail to illuminate when you press the brake pedal.
- Brake Lights Stay On: The switch can fail in the 'on' position, leaving the brake lights constantly lit. This can confuse other drivers and will drain your car's battery when parked.
- Cruise Control Issues: If your Continental has cruise control, a bad switch may prevent the system from engaging or, more dangerously, prevent it from disengaging when you press the brake pedal.
A Note on a Historical Recall
In May 1980, a recall was issued for some 1980 Lincoln Continental models because oil contamination could cause the brake light switch to fail. This could lead to the brake lights not working and the cruise control not disengaging with the brake pedal. While this recall is decades old, it highlights a known potential point of failure for the original switches.
Choosing the Right Aftermarket Switch
For a vehicle of this vintage, finding a New Old Stock (NOS) OEM Ford part can be difficult and expensive. Aftermarket parts are a reliable and cost-effective solution. Standard Ignition is a well-known brand that has been making quality automotive electrical parts for decades. Their switches are made with quality materials like copper conductors and are fully tested for performance.
Crucially, you must identify which switch your specific car needs. There are two common versions for this Lincoln generation:
- 2-Terminal Switch: For models without cruise control.
- 4-Terminal Switch: For models equipped with cruise control. The extra terminals handle the cruise control deactivation circuit.
Pro Tip: Before ordering, look at the existing switch on your brake pedal assembly. Count the number of electrical terminals to ensure you purchase the correct replacement part.
