Is the turn signal flasher and hazard 1 same in a 1999 Chevrolet Cavalier?

No, the turn signal flasher and the hazard flasher are not the same in a 1999 Chevrolet Cavalier. They are separate components, although they might share some circuitry. The hazard flasher operates all four turn signals simultaneously, while the turn signal flasher controls the individual left and right turn signals. They are likely different components and will have separate fuses as well.
