If you turn the ignition and you hear a clicking sound or nothing happens at all, it may be a sign that the starter is not working properly. Additionally, if you hear a grinding noise when you try to start the car, this could also indicate a failing starter. Lastly, if you notice that your headlights or interior lights are dimming or flickering when you try to start the car, this could be a sign of a failing starter.
