I Have An O4 Silverado Z71. I Have Had The Problem Before But I Would Just Take It Back To The Dealer And It Would Get Fixed Under Warranty. This Will Be The Third Time This Has Happened. Anyway I Can Be Driving And Try To Engage The Cruise Control And It Does Not Engage. I Think It Is The Switch On The Sterring Colum. Does Anyone Know If That Could Be It. Thanks For The Help Ahead Of Time.
