Well its either the switch or the flasher relay. Make sure relay is getting signal from switch to signal. Use a volt meter to check for voltage at the flasher relay when you hit the turn switch . No B+ the switch is bad . If B+ is there then check that relay is sending it to bulb .No B+ to bulb then its the flasher relay.

1990 Corolla blinkers working intermittently only

If the flasher ("blinker can") was bad, It would be rare that it would work intermittantly. We rarely change the fashers, they are pretty reliable. My suggestion to you is to check your turn signal switch. If the signals are not flashing, cycle the switch back to center & left/right; hold it in the "on position".... Do the lights the start to work? if so, replace the turn signal switch.
