Hello, there should be a backlight, check your panel dimmer and make sure it's not set to low.

Sorry to be so specific, but as you can see by the picture, everything else is backlit blue even the power and menu buttons, but the two bigger knobs that say auto and sync should have the blue glow in back, is that correct? Because that hvac unit is brand new from dealer

That's correct, It not uncommon to have a new part with an issue. They should swap it out for you at no additional cost.
