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.
