No Turn Indicators

94 Grand Am 3.1 , turn indicators not working, nothing, no green light, no audible, nothing. Any ideas?

UPDATE:
After turning the emerg flasher and signal stalk on and off a few times, I now have the four way emerg flashers working (including dash indicators and all four exteriors), however the left turn signal still won't work. The green indicator illuminates solid green but no exterior effect at all. Thanks dee088 for the suggestion.
UPDATE :
After applying WD4o to the signal switch everything is now working.

hey, I too had the same problem on my '95 grand am and just had it fixed. We replaced the back bulbs-nothing, checked out fuses-nada. We went underneath the dash (had to remove dash covers) to find the relay. After looking at two manuals, we found it on the left(manual said right) hand side way in back and up. We have flashers now. Also it could be your turn singal switch (malfunction switch). Hope this helps
