It's not clear from your posts:

1. Does the servo hold vacuum?

2. Have you checked for vacuum leaks at the brake switch?

3. Confirmed proper cable adjustment?

Thanks for the help guys but ive checked all vacuums with vacuum gauge and everything seems fine ive checked the brake switch got power and vacuum there seems fine and after i let it run for a min i can pull the little vacuum hose off at the servo and it hisses so i suspect it is fine but i honestly dont know about cable adjustment i put it back in the spot where it had wear marks on the plate that sticks off of the servo im so lost ive read every post i could find and done every test i could find to to from power checks on everything from vss to ecm to cruise control module brake switch to servo and got power and vacuum but cruise wont do nothing....any advise would be great because im lost fellas and how do i adjust the cable???
