What is the fix for non working turn signals on a 1993 Cougar when the hazard flasher and all associated bulbs work?

it is either bad signal flasher or bad signal switch assembly try another flasher, swap the hazards one in place of the signals one if the hazards work right now if the hazrds dont work either then it is most likely worn switch assembly(common problem in these cars) i am working on a corsica right now that has no brake lights except the third one and it is the switch assembly worn out in it, flashers are good in it
