My Cruise Control doesn't work on my civic

I have a 98 Civic Ex, and noticed that my cruise control no longer works. Does anyone know where i can locate a fuse or anything. I rarely use the cruise control, only on long trips. The lights turn on, but the car slowly declerate. I have no idea what went wrong, I haven't change anything or added anything to the car recently, or since the last time I used the cruise control.
