cruise control problems

[Abe]

I am looking for someone to help me with fixing my damn cruise control on my 78k20<p>i just purchased a new transducer and that did not fix it. the switch ohm readings are in spec, and the vacuum lines are all ok, I am not getting power to my transducer for some reason and i dont know if the switch on the brake pedal might be the problem. it does not engage at all. anyone out there that knows the cruise on this vehicle i would really appreciate your assistance. 400cuin with a th400 tranny.<p>-Abe
