Interior • Headlight switch icons are not lit blue

I was looking into the MKT headlight switch swap for my 2012 SEL and noticed it was discussed that the switch icons light up blue. My switch doesn't light up at all?! Apparently, it is supposed to light up with the positions in blue? Actually the only part that lights up is the fog light indicator when you pull out on the switch. I have swapped it out for a known good switch and it also doesn't light up. The instrument cluster lights up fine. The interior light roll switch that controls the dimming of the cluster and such does work, but it is kinda flaky in some places as you roll it. Would that cause the headlight switch to not light up?
Any ideas what else I could check and/or a continuation of troubleshooting ?
