ck your speed control servo under the hood. ck connetor for brake fluid if it has fluid,you need to replace deactivation switch on master cylinder. the horn uses the servo as ground. hope this helps

The horn and cruise control I believe use the same relay ground, so if one relay is out, the other one wont work, and i also thing they are hooked into the same fuse in the fuse box.
