´93 VR6 cruise control doesnt work

Ive not had this car long and the cruise control didnt work when I got it. Well, I dont think it works -- it doesnt seem to do anything at all, but I´ve never had a car with cruise before so maybe Im just not doing it right? I move the switch to "on" and then "set". All other combinations dont seem to do anything either. I dont really need it and certainly wouldnt pay much to have it fixed, but could it be something simple like a fuse or relay? Is there any way I can test what does and doesnt work?

Thanks in advance,
Andy

Is it a manual or automatic?If it a man. trying,with your foot,to pull up on the clutch pedal.At the same time hit "Set" on your CControl.Hold for a few seconds.If it catches(CC)then its the switch on the Clutch under there.Check it out.Hope it helps you get somewhere.
