possible bad turn signal switch in the steering column or a bad ground on your turn signals.
The hazard switch itself is bad. The flasher module for the turn signal is built into it. Replace it yourself for 100 dollars(cost of part).

The same problem happened to me, I l;ost all dash lights on my 2000 impala. It turned out that the head light switch went bad and had a burned terminal on it. All of the dash lights are routed through the headlight switch. The switch costs about $100.00 from GM and is easy to replace
