There are two flashers in that diagram, one for the hazards and one for the turn signals.
Also two different fuses.
Make sure you replaced the correct flasher.
Working from that diagram, if the hazards work, the bulbs are good.
Since the turn signals are on individual (left / right) switches, it would be strange if both went bad at the same time.
That pretty much leaves the turn signal flasher or the wiring from the flasher to the turn signal switch(es).
