Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts during repairs.

2. Inspect and Adjust Brake Light Switch

Locate the brake light switch, typically found above the brake pedal.
If misaligned, carefully adjust the switch position so it correctly engages when the pedal is fully released.
Ensure that the switch clicks when pressed and released.

3. Replace Brake Light Switch (if needed)

If the switch is faulty, remove the old switch by disconnecting its wiring harness and unscrewing it from its mount.
Install the new brake light switch by securing it in place and reconnecting the wiring harness.
Ensure the switch is adjusted properly to allow full disengagement of the brake light circuit when the pedal is released.

4. Inspect Brake Pedal Assembly

Check for any obstructions within the brake pedal assembly that may prevent it from returning fully to its original position.
If necessary, lubricate pivot points on the brake pedal to ensure smooth operation.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Test the brake lights by pressing the brake pedal to ensure they turn off when the pedal is released.
