I know that I have seen this question out their, but have not seen anybody get a resolution. I have an 08 Crew Cab 4.8l, my cruise control does not work, I have the switch on the steering wheel which continues to light up. No codes are in the system, and I can see the computer is reading the on/off switch by verifying it with my Solus Scanner. I have had other issues with the truck like passenger sided door actuators intermittently don't work, and when it is cold outside (not very often as I live in AZ) I get an error "Service Stabilitrak", and lastly radiator fan does not kick on unless AC is on. Has anyone else had problems like this, or does anyone have a resolution. Have checked fuses, and traced wires as far as I could before having to tear apart the dash.

 

hefegringo84,

I am sorry to hear that you are experiencing these issues. Have you spoken with your dealership to confirm a diagnosis?

Thank you!
Elizabeth, Chevrolet Customer Service

 

Check this post "2008 silverado 1500 big problems." I had a similar issue and it ended up being the positive battery cable end. I have pictures if you'd like to send me your email.
