Flashers work fine but turn signals dont work

SOURCE: locating the turn signal flasher on 1993 corsica

The turn signal flasher is mounted in a clip on the right side of the steering column support bracket. The hazard flasher is located in the component center, under the instrument panel, on the right side. Replace the flasher by unplugging the old one and plugging in the new one.

SOURCE: flasher or turn signal switch

When you select left or right do any of the bulbs come on? If you select left check front and back left side if one of the bulbs did not come on the flasher will not work. Change the bulb that is out. Same with the right. If the fuse for the turn signal is good (check fuse or replace do not use visual, some appear to be good but are not).
The emergency flasher is different from the turn signal flasher. Look at manual for location of turn signal flasher. If you manually lift and lower turn signal control you may hear a clicking under the dash to locate the flasher.

SOURCE: turn signals and back up lights dont work.

Test the circuit board wires on the back side of your taillights where the bulbs go in to see if power is going there with the blinker on, if yes replace the circuit board (quite common with these trucks). If there is no power back there check your flasher relays for each turn signal, assuming they dont click off and on when you tip the turn lever. if all else fails, head for the multifunction switch behind your steering wheel inside the column that your turn signal/wiper/cruise control lever is connected to.

Sounds like the flasher unit to me. Normally the emergency flasher and turn signal are separate.
