Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Adjust Brake Light Switch

Locate the brake light switch mounted on the brake pedal assembly.
Check the alignment of the switch; it should be activated when the pedal is pressed and deactivated when released.
If misaligned, adjust the switch by loosening the mounting nut and repositioning it. Retighten the nut securely.

3. Replace Brake Light Switch (if faulty)

If the switch is defective based on multimeter tests, remove it by disconnecting the electrical connector and unscrewing it from the bracket.
Install the new brake light switch by reversing the removal steps.
Reconnect the electrical connector ensuring a secure fit.

4. Inspect Brake Pedal Mechanism

Check the brake pedal return spring for proper operation; replace if weak or broken.
Ensure the pedal pivots freely and does not bind against the pedal assembly.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and press the brake pedal to check if the lights turn off when released.
