My cruise decided to stop working one day. I was intermittent for awhile then turned off all together.
Tried to run the diagnostics, but nothing came of it.
The cruise does not work at all, when I hit the button there is no green light anymore.
Haven't really found the problem yet.
Ok what I have done thus far.
1. Checked correct working order of parking brake.
2. " " of brake light switch.
3. Checked clutch switch, something was funny with it, have to recheck.
4. Vacuum lines are all good.
5. Checked correct working order of vacuum pump.
6. " " of Actuator.
7. " " of Vacuum switch.
8. ECU-IG fuse is good.
9. Took apart the clock spring in the steering wheel. Everything was perfect.
10. I get voltage through the relay in the switch through the steering column.
11. Brake fluid switch is good.
12. GAUGE fuse is good.
Checks on CCC or Speed Control unit I should say.

Everything checks out except the clutch switch is strangely high resistance when pushed in. 2.4 Mega ohms. No continuity when released.
Any ideas now?
Edit: I also took apart the cruise switch to make sure everything was working a ok. It checked out ok, I can feel the relay click when I hit the button.
