Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
Normally the switches in the steering wheel or the clock spring are to blame for intermittent operation of the cruise control. A volt ohm meter can be used to diagnose this system when not working at all. For an intermittent concern the switches, BCM and ECM need to be monitored with a scan tool using freeze frame data. Do you have access to a scan tool?
This is my 1st answer of what can be many. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. At the top of your screen is the rating box that you only get to use once. Please make sure to complete the mandatory rating when ready or reply and say "I am pleased with my answer". Not rating or rating 1-2 stars does not benefit you nor me in any way.
Hello again Chris here,
