1995 Pontiac Firebird Turn Signal Stopped Working

When I first bought it 7 months ago the turn signal was working, then about 2 and a half weeks after I purchased the car the turn signal just stopped working.
The bulbs are not burned out, and the the hazard lights still work.
Various "car friendly" friends suggest it may either be the relay, or a switch needs replaced.
The stick used to turn on the turn signal still moves, and other things on it still work - like the brights, the windshield wipres, cruise control, etc.
The only thing that won't work are my turn signals.
I also had a friend check the fuse - which he said is fine.
My question is, can I fix this myself, if so - what do I need and how can I do it?
Thanks for any and all help on this in advance! :)
