turn signals just wont work!

Both of my turn signals recently just completely stopped working at the exact same time. I told myself it was obviously the fuses so i changed them and it worked. However after about 5 minutes they just stopped working again. its a 2001 buick century, I am using this car for about two months until i get another car and its the first buick i have so i'm not too familiar with them or there common problems. Anyone have an answer for this??
thnx n advance!

Are you referring to the signals not flashing or are neither left or right lights at the IP not turning on to include the respective outside lamps.

nope, the lights just wont even flash. Yes both lights.
