There are literally dozens of things that will cause the cruise control to fail. For example, an over/under charged battery, a bad park/neutral position switch, binding throttle linkage, EMI on the speed sensor signal circuit, even burned out brake lights.
I have the diagnostic procedures as listed in the service manual but I would need some more specific details of the symptoms.

my switch that is on the clutch pedal was my culprit... there are 2 switches on the clutch pedal one in front and one behind.... if i remember right the one in the front is the one for the cruise and the one in the back is for starting the car...

An M6 doesn't have a park/neutral switch - it's only on automatics.
EMI means "electromagnetic interference". That can be caused by a number of things but the most common is a high-powered stereo system incorrectly wired to run the power alongside the speed sensor wire. (It can also be caused by an atomic explosion
)
What are your symptoms? Will it set but not hold speed? Does it not turn on at all? The diagnostic procedure is different depending on symptoms and usually involves using a diagnostic computer.

Yep. Always check those. I had to screw the upper one down a few threads in both my '01 and '02 after installing Mcleod clutch master cylinders in both of them.

I created a .PDF file of the diagnostic procedure for an inoperative cruise control. You can download it here. Of course, the first several steps won't be much use since they refer to connecting a diagnostic computer to the car.

BTW, there isn't a fuse for the cruise control in the dash fuse panel. The fuse is a 15A mini fuse in engine wiring harness junction block #2 under the hood on the front of the left wheelwell.
