How do i disable onstar chevy silverado?

If You would like to disable OnStar for the 2014 and up Chevrolet Silverado, follow these steps. Youll need a plastic trim removal tool. Theyre cheap and can be bought for about $5. To start, gently pry the trim around the stereo and display, by evenly working Your way around the entire unit. Be patient to avoid cracking any part of it. Once off, disconnect the two clumps of wires at the bottom. Now You need a drill and drill bit (9/32) to unscrew four screws at each corner of this frame. Once off, You will see three color coordinated wires in yellowish, brown and red. Disconnect all three of them, and Your Onstar should be disabled.
