2004 Chevy Malibu Turn signals

At times the direction signals will not operate. I checked the owners manual and they do not speak of a signal flasher. I checked the 10 amp fuse in the panel at the left side of the dash, and it was good. I remember in my older cars that a turn signal flashes was to be found on the fuse panel. Do they still use one of these, and where is it? Thank you.
