Do you have any idle problems, surging or stalling?
The cruise control module located under the passengers floor mat also controls the idle speed. The '94 suffered from disintegrating wiring harnesses and this includes the harness going into the throttle actuator.
The electronic module itself if quite reliable for that year but you could have a problem with the throttle actuator, stalk switch, or speed sensor in the instrument cluster. Do you have any brake lights out?
Did you check the fuses visually or with a meter?
