Why do my hazard lights work, but not my turn signals?

Why do my hazard lights work, but not my turn signals?

Turn signals only work when the ignition is on; hazard lights work whether the ignition is on or not. The two systems have separate power supplies, so they have separate fuses. You may have a blown fuse. Different vehicles use different circuits, and it is not possible to accurately diagnose the fault with the small amount of information provided.

How is the hazard light on and off?

The hazard light switch is not a simple on/off switch. In the “on” position, a fused battery feed connects to left and right turn signal.
