Hmmm... when you say your blinkers aren't working at all do you mean:
-they light up but don't flash
or
-they don't light up at all.

If they light but don't flash, it's the flasher relay.
If they don't light at all, look at the turn signal switch.

Another test: hit the emergency flasher button on the dash. If the lights flash, the flasher relay is good and it's probably the turn signal switch or it's wiring.
