These are the system components of the C/C
1. Vehicle Speed Senssor
2. Cruise control module
4. Brake Switch
5. Clutch Switch if Manual Tranny same as the brake switch operation
6. Throttle Linkage
Does your Speedometer Works? -If not it won't hurt to check the VSS if its the VSS it will not give the Brain (Cruise Control Module) the speed signal or when the CCM goes bad either it will not understand the signal from the VSS or unable to send the signal to the actuator.
If its not an obvious problem like disconnected harness, broken wire, blown fuse and leaking vacuum hose then most likely its the CCM or it switches that sets the speed and contains other functional areas such as the resume and accelerate.
Check the vacuum diaphragm inside the actuator for leak this problem will cause it not to properly operate or it will not set at all. Also the linkage for disconnection or broken chain bead
BTW the Actuator works the same way as the Brake booster one pulls the accelerator the other gives your foot a rest.
Good Luck! This is the best I can give, not there to see what's happening
Happy New Year 2007
