Yeah, but if it's leaking vacuum, it's bad.

On my 1995 Escort's factory service manual there are tests you can do to essentially bypass the steering wheel switches.

In that case, if you disconnect the vacuum hose going to it and connect a vacuum hose from a vacuum pump, the cable should move when applying vacuum. You got one of those Mityvac hand held vacuum pumps ?
it has constant wacuum.must have a valve that closes to pull the cable.it does not have a regular system that you can move the cable.its all internal

It might be a device with a solenoid operated vacuum valve. You push the cruise control button on your steering wheel and an electrical signal energizes the vacuum valve solenoid. If the solenoid is burned out, that might be your problem.

hopefully you are right. I hope i can find a good one at picapart

Figured it out. The cable has a mount near where it connects onto the injection pump. The mount wore out so instead of the cable pulling on the pump lever it was being pulled to the pump instead.

An $.18 hose clamp fixed it.
