Cruise control stopped working (neither normal nor adaptive). When I press the dial to "set" the cruise speed nothing happens, also I read I should be able to change between normal and adaptive cruise by pressing the "cancel cruise" button, but when I do nothing happens.
Truck comes from a GM employee who had diagnosed it as the steering wheel being the culprit (in case the switch was defective); he gave me a new steering wheel with the truck which I swapped but it did not work.
I guess the easy route would be to take to the dealership for them to diagnose, but since that will take longer and usually several visits: What else should I try?
Any specific fuse or something else I should check?

I upgraded my factory radio and used the pac rp-5 recommended wiring harness. Factory settings were set and the radio controls on the right side of the steering wheel all work fine. However the left side cruise control doesn't work anymore. Any ideas on how to correct this?

This weekend I changed my rear rotors. It was a simple swap, old ones off, new ones on. The next morning I went to start the truck and barely got it to turn over and the DIC threw a message up saying service trailer brake system. My radio also completely reset and when I press on my brakes all lights dim. Any suggestions in what this could be?

I need to add a second battery to my 2020 Silverado CC. In previous years, it was simple. There was even a place. I don't see a single option or place to fit one. I called my local dealer multiple times to ask, but they never call back. Anyone else figured out a way to do this? Where is a good spot?
