Quick question for everybody: Is the little wheel (and the corresponding symbols) for the interior dash light dimmer/dome light switch supposed to be illuminated at night? My headlight switch is, as well as the cargo light symbol, but not the dimmer switch. I was wondering if I have a burnt out bulb, or if GM just cut corners on the work truck. Thanks for your time.
