Here's a breakdown:
* Normally flashing (often slow): This is normal. It means the system is armed and functioning. You'll typically see this when the car is locked.
* Solidly lit or rapidly flashing: This is usually a sign of a problem within the anti-theft system. It could be:
* Faulty sensor: A sensor in the car's security system might be malfunctioning.
* Key fob issue: Your key fob might be malfunctioning or its battery might be dead.
* Problem with the car's computer system: There could be a more serious issue with the car's computer or electrical system.
* Aftermarket alarm issues: If you have an aftermarket alarm installed, the issue might originate there.
What to do if the light is on solid or flashing rapidly:
1. Try unlocking and locking the car with your key fob: This sometimes resolves minor issues. Replace the fob's battery if needed.
2. Check your owner's manual: Your manual might have specific troubleshooting steps for the security system.
3. Consult a Buick dealership or qualified mechanic: If the problem persists, professional assistance is necessary. They can diagnose the issue and repair the problem, potentially saving you from larger issues down the road. Ignoring a persistently illuminated security light is not recommended.
It's important to note that the exact behavior of the security light (flashing rate, etc.) might vary slightly depending on the year and model of your Buick Century. Your owner's manual will provide the most accurate information for your specific vehicle.
