Sorry for the simple question. I have a 2020 Silverado 2500 HD and I cannot figure out how to get the cab mounted cargo light to come one. The obvious button that illuminated the permitter lights, in-box lights, and tailgate light doesn't seem to turn on my cab mounted (up with 3rd brake light) cargo light.
Am I missing something or is this another delete from gm (e.g console storage, read map pockets,...)
