Cruise Issue '97 Jimmy

Hey all!
I have a 97 Jimmy and I am having a problem with the cruise control. It will not engage at all-just wont work. I got all the wiring diagrams and diagnostic charts and everything appears to be fine, the
test light and meter is showing a good connection and good voltage all around. The diagnostic chart always points towards the cruise module, so I had it replaced. Still no go, so I did all of the testing over again and again, it pointed towards the cruise module. I replaced it once again with a unit from a vehicle which I knew had a working moduled and it still wouldnt engage. Any other ideas of what it would be? Any suggestions would be greatly appreciated. Thanks!

I did get your message. Thanks to all those that have responded so far with your suggestions. Since my posting I have replaced the brake light switch with a brand new one, along with the cruise control cable even though the old one seemed to be working fine. I have also had all switch functions tested and wiring tested and all is checking out okay, however the stupid thing refuses to work. So, keep the suggestions coming and hopefully one of these days I will actually get my cruise working.
