Cruise Control not working

I was wondering if anyone can tell me if there is a fuse for the cruise control on a 93 ls. The light comes on on the switch but it wont work, no light on the gauges. The haynes manual says first check the fuse…well I cant find a fuse. Can anyone help?

There is a little plastic stopper piece that engages the cutout switch on either the clutch pedal or brake pedal, depending on if you have a 5speed or auto. This piece tends to fall apart and go missing after 10 years or so, i’d check that first, it would cause the problem you are having.
