Is a Faulty Brake Light Switch Keeping Your Oldsmobile in the Dark?
A failing brake light switch is a common issue on classic cars like the 1961-1967 Oldsmobile 98. Over decades of use, the internal contacts can wear out or the mechanical plunger can fail. The most frequent symptoms are brake lights that don't turn on at all, or lights that stay on even when you're not braking. 🎬 Watch this guide on identifying symptoms of a failing switch. Before assuming the switch is bad, it's wise to first check the brake light bulbs and the fuse, as these are also common and simple failure points. However, if the bulbs and fuse are good, the brake light switch is the next logical component to inspect.
Choosing the Right Aftermarket Switch
For a vehicle from this era, finding a "new OEM" part from General Motors is nearly impossible. The market is served by aftermarket manufacturers who produce new replacement parts. This is often a good thing, as modern manufacturing can result in a more durable switch than the original. You have a choice between different tiers of aftermarket brands.
- Professional Grade (Standard Ignition): Standard Motor Products (SMP), who makes the Standard Ignition brand, is a long-established and trusted name in the aftermarket. Their parts are often used by professional mechanics and are known for quality and reliability. For a critical safety part, choosing a brand like Standard provides peace of mind.
- Value-Oriented (Skyward): Skyward represents a more budget-friendly option. While there is less brand-specific information available for Skyward's quality on this particular part, value brands are a practical choice for owners looking to complete a repair at the lowest possible cost. For a simple switch, this can be a viable option, though long-term durability may vary compared to premium brands.
Pro Tip: On these older cars, electrical problems are often caused by bad grounds. While replacing the switch, take a moment to clean the electrical connectors and ensure the switch has a solid ground connection. This can prevent future issues.
