How to fix my Honda Prelude blinker lights?

I have a 1993 Honda Prelude, and all of sudden, the bliker lights are not working. Right or Left, they are all won't work. They seem dead. I checked the bulbs and they are fine. Is there any fuse somewhere that I need to replace? where is it? what else could be the problems? thank you. You could also email me at viking93718@yahoo.com
