cruise control does not work

I had a problem like this, under the hood the cruise control unit is there ,there's vacuum lines going to it ,see if there connected. That all I can offer...its worth a shot unless that unit is no good or fuses?..

It's a small vacuum hose. I had one snap and my light come on and it wouldn't work. Tape up that vacuum leak on that small hose and it should fix the problem.
