Yes, take it to you local Ford dealer, they have the tools to locate the fault fairly easily.

If there werent airbags involved, you would have had multiple 'how-to' responses.

There are airbags involved, so dont mess with it.

1. it's dangerous in one way or another.. may go off when you dont want, or NOT when you do want

1. cheaper to pay to fix CC than Airbag system

Other than to make sure all the vacuum lines, and cable from the servo to throttle are intact.

ALLDATADIY.com has a lengthy procedure to debug cruise control problems. My 1999 Windstar cruise control went out last week with similar symptoms as yours. The mechanic replaced a $10 Brake Pressure Switch on the back of the master cylinder. Apparently this switch will cut-off the CC when you apply the brake. There is another switch called the brake switch that disengages the CC when you press the brake pedal. My understanding is that the Brake Switch is primary and the Brake Pressure Switch is there in case the Brake Switch fails.

I think the horn and cruise control share a fuse, so the first thing I would do is verify that your horn works. If it works then check both Brake switches.

I chose to take it to a mechanic that knows how to diagnose cruise control problems.

Check if the switch on the master cylinder is leaking, they go bad alot
