* The parking brake (emergency brake) is engaged: This is the most obvious reason. Even a slight engagement can trigger the light and chime. Carefully release the parking brake lever completely.
* The parking brake switch is faulty: This switch senses whether the parking brake is engaged. If the switch is malfunctioning, it might be sending a signal that the brake is engaged even when it isn't. This is a common cause of the problem and requires replacing the switch. The switch is usually located near the parking brake lever itself.
Less likely, but possible causes include:
* Wiring problem: A short or break in the wiring between the switch and the light/chime circuit can cause the light to stay on. This requires tracing the wiring to find the fault.
* Faulty brake light switch: Though less common, a malfunctioning brake light switch can sometimes interfere with the parking brake circuit.
Troubleshooting Steps:
1. Check the parking brake: This is the first and easiest step. Make absolutely sure the parking brake is fully released.
2. Inspect the parking brake lever: Look for any physical obstructions that might be preventing it from fully releasing.
3. Check the brake lights: Ensure that your regular brake lights are working correctly. A problem with one could indicate a deeper electrical issue, potentially affecting the parking brake circuit.
4. Inspect the parking brake switch: If the brake is definitely disengaged, the switch itself is likely at fault. You might need to consult a repair manual or online resources to locate and visually inspect the switch for damage.
If you've checked these and the problem persists, it's best to take your LeSabre to a mechanic. They have the tools and expertise to diagnose and fix the underlying electrical problem, whether it's a faulty switch, wiring issue, or something else.
