Blown fuse.
Bad flasher.
Did they ever work? How about some history.
See attached wiring diagram.

Two flashers in the jungle (underdash)

Someone, I don't remember whom long ago, explained to me why they hide the turn indicator flash unit up in the loom, on either side of steering colunm, and put the hazard flasher on the fuse block, maybe steering column with flasher curcuits gets installed, much later than body lighting.
Anyway hazards work without the "key on" (signals need the key on).
Therefore Two flashers are in the wiring.

If you have looked at the diagram I sent you you will see that the system has (2) flashers. The hazard flasher and the turn signal flasher.
Try the following making reference to the diagram.
1- If the hazards work swap the flasher with turn signal flasher. If the turn signals work that means you had a bad flasher.
2- If that doesn't work get a test light with a probe. With the key ON test the fuse block to make sure the TS fuse is not blown. It may look Ok but still could be bad. Check both sides of the fuse. The light should light on both sides.
3- If the fuse is Ok insert the probe in the back of column connector plug (column side) to make contact with the purple wire terminal. If you DO Not get 12 volts + make sure the connector is solidly pushed together. If so remove the flasher and install a jumper in its place. If you don't get 12 volts + you have a broken wire somewhere. Check the connections by pulling on the wires at all the plugs or connectors in the circuit.
4- Check the back of the fuse block for a bad connection on the pink wire.

first thing i try'd was check the purple wire on the column nothin. i left the key on checked every fuse all had power bolth sides of the fuses but the turn sig fuse shoulda try'd that from the start. might i add those fuses are hard to pull out with out them coming apart.

yay now dont have to worry about the popo's pullin me over for bit
