Ensure all connectors are seated properly and free of corrosion.

4. Reset the Brake Light

After replacing the switch or repairing wiring, reconnect the battery if it was disconnected.
Use an OBD-II scanner to clear any stored error codes related to the brake system.
Turn the ignition to the "ON" position without starting the engine and check if the brake light goes off.
