    The cruise control has two switches, one electrical/one vacuum, mounted
    on the brake pedal support. The electrical switch turns off the power
    to the controller when the brake pedal is depressed. The vacuum release
    valve is also mounted on the brake pedal support. It vents cruise
    control servo vacuum when the pedal is depressed. The venting action
    serves as a second disengagement system.

    The ECM should show trouble codes associated with a cruise control
    problem. The ECM also has the capability of testing the various
    switches in the cruise control system.

    Hope this helps

    Baldy, we are all assuming a bunch w/such little info. But while we are
    guessing, let;s guess the switch actuated by the brake pedal needs
    adjusting. Putt and I are just trying....HTH & god luck, s
