If the turn signal switch is defective, it can prevent the turn signals from activating when the headlights are on, leading to turn signals not working with headlights on. Fortunately, this problem is relatively easy to fix. Replacing the old turn signal switch from Amazon with a new one should restore the normal operation of the turn signals.

• The first is a faulty turn signal switch, which is the component responsible for turning the turn signals on and off.
• The second is a problem with the headlight switch. In some cars, the headlights and turn signals are connected and if the headlight switch is not working correctly, it can disrupt the turn signals. 

If you are having this problem, it is important to have a professional inspect and diagnose your vehicle to determine the exact cause of the issue.
