Buick 2000 Cruise problem

I have a Buick LeSabre 2000 that the cruise just quit on the open road. I have metered all the switches from the CCM connector to the steering wheel & brake. All are OK. I suspect the module but can anyone tell me how can I check for sure before spending $200 + ??

I asked this question and never got an answer. Hope you get one so I can benefit.
Chris.
