Check the wiring harnesses, bulbs, relays...

Might be the relay if neither the turns nor the hazards work. The hazards and turns are on different branches of the dash wiring harness and it's highly unlikely that both of them rattled loose at the same time, miraculously.

Bulb, both of them blowing at the same time is possible but not likely.

Relay.... is it clicking when the signals/hazards are on? Do you year that "ticktick..ticktick...ticktick.." clicking? If you don't, your turn signal relay is fuxxored. Luckily they are cheaply enough found.

Other than that....... yeah that's pretty much all I can think of and all it would be. Double check the fuses and listen for the clicktick of the relay.
