Default heater AC panel lights

2k c5 AC/Heater control lights. I don't have the display screen one just the generic 3 turn **** one.

Issue

When I turn on my headlights the ac/heater panel lights up for a second and goes off. The ac light and rear defog light buttons don't light up showing on or off.

If my headlights are off The ac and rear defog buttons light up if I turn them on to use them.

Before I tear apart this dash this weekend what should I look out for?

Thanks

Have you tried messing with the dimmer switch while the lights are on?
