Chevrolet Brookwood Ignition Switch Guide: 1969-1972
Is your classic Brookwood having trouble starting or staying running? Your ignition switch might be the problem.
- A bad ignition switch can cause a no-start condition or dangerous stalling while driving.
- For this classic vehicle, a new aftermarket part from a reputable brand like Standard Ignition is the best choice.
- This is a very DIY-friendly repair that can be done in about an hour with basic tools.
- While replacing the switch, always inspect the wiring harness connector for damage or corrosion.
Signs of a Failing Ignition Switch in Your Brookwood
An ignition switch in a classic car like the 1969-1972 Brookwood wears out over time. The metal contacts inside get dirty or break, causing electrical problems. Watch for these common signs:
- Engine won't crank: You turn the key and nothing happens. You don't hear the starter motor try to turn the engine.
- Stalling while driving: The engine might suddenly shut off, especially when you hit a bump or jiggle the keys. This is a serious safety issue.
- Intermittent power to accessories: Your radio, heater fan, or dashboard lights may flicker or stop working randomly.
- Key feels stuck or is hard to turn: While this can be a lock cylinder issue, a binding switch behind it can also be the cause.
Choosing the Right Aftermarket Ignition Switch
For a vehicle of this age, finding a new original GM part (often called New Old Stock or NOS) is nearly impossible and very expensive. Used switches from a salvage yard are an option, but they are just as old as the part you are replacing. A new aftermarket switch is the most practical and reliable choice.
When shopping for your Brookwood, you'll likely see two types of brands:
- Standard Ignition (Standard Motor Products): This is a well-known brand that has been making ignition parts for a long time. They are generally considered a quality choice for American-made vehicles from this era. While any mass-produced part can have issues, Standard has a reputation for good fit and using proper materials like copper conductors.
- Replacement / Store Brands: These are generic or white-label parts. Quality can be a gamble. Some owners in forums have reported issues with these parts not fitting correctly or failing prematurely. For a critical part like the ignition switch, spending a few extra dollars on a known brand like Standard Ignition is a wise investment.
Pro Tip: While you are replacing the switch, inspect the wiring connector. After 50+ years, the plastic can become brittle and the metal terminals can get corroded. Sometimes the connector, not the switch, is the real problem. Replacement wiring pigtails are available and are a good idea to install at the same time.

Frequently Asked Questions
Is the ignition switch the same as the lock cylinder?
No. The lock cylinder is the mechanical part your key slides into. The ignition switch is the electrical component that the lock cylinder turns. They are separate parts, though they work together.
Can I replace the ignition switch myself?
Yes, this is a common DIY job for classic cars. It typically involves disconnecting the battery, using a paperclip to release and remove the lock cylinder, unscrewing a bezel nut from the dash, and then unplugging the old switch and plugging in the new one. You should always consult a repair manual for your specific vehicle.
Were there any recalls for the Brookwood ignition switch?
No recalls or technical service bulletins (TSBs) were found for the ignition switch on the 1969-1972 Chevrolet Brookwood. This is not unusual for a vehicle that is over 50 years old.
Will a bad ignition switch drain my battery?
Yes, it can. If the switch fails in a way that keeps an electrical circuit active even when the key is off (like the 'accessory' or 'on' circuit), it can drain the battery overnight.
