Left switch cluster bulbs don’t work

[GrindhouseProject]

I went to replace the left switch cluster (fog light/rear defrost bulbs) 74 bulbs for the symbols and even with new bulbs they don’t work. Even stranger the rest of the dash light work. Would anyone have any ideas?

Have you checked with a multimeter to see if you're actually getting power to those sockets when the dash lights should be on?

What year?
