* Brake light switch: This is the most common culprit. It's a small switch that activates the brake lights when you press the pedal. It could be faulty, stuck, or have a broken wire.
* Faulty brake lights: One or more of your brake light bulbs could be burned out and shorted, causing a constant current flow.
* Wiring issue: A short circuit in the wiring harness leading to the brake lights can also keep them illuminated.
* Brake pedal position sensor: Some vehicles use a sensor instead of a simple switch. A malfunction in this sensor could cause the lights to stay on.
Do not attempt to manually disconnect the brake lights. This is extremely dangerous as it will disable a crucial safety feature.
Instead, you should:
1. Check your brake lights: Have someone help you check if your brake lights are actually stuck on. Look at both the rear lights and the third brake light (if equipped).
2. Inspect the bulbs: Try replacing the bulbs. This is the easiest fix and often solves the problem.
3. Consult a repair manual: A repair manual specific to your 1996 Oldsmobile model will provide diagrams and troubleshooting steps.
4. Take it to a mechanic: If you're not comfortable working on your car's electrical system, take it to a qualified mechanic for diagnosis and repair. This is the safest option, especially given the potential safety risk involved with malfunctioning brake lights.
Leaving your brake lights on will drain your battery and is a safety hazard. Get it fixed as soon as possible.
