I have a 2017 Chevy Traverse Ls Awd. I’m having a problem with electrical, is the DIC issue. It’s dark cannot see or read it, even in daylight and dark. The dimmer switch which is next to the headlight control knob does not dim the dash, the high beam to leave on does not work either, but when you pull towards you for a quick high beam it will work. Turn signals and four ways work. The gas gauge and the odometer and rpm gauges work. I thought it was the little knob in the middle of the dash up by the windshield if it was dirty or something, I had a sunshade screen cover it one day and removed it and it came on the DIC but not bright. I want to fix this myself but there is no YouTube video for it and I don’t know if there is a recall, could anyone help with this, only had the truck for two years.
