All interior illumination other than footwell and opera lights is dead, no low beams(parking and flash to pass work), checked all fuses when this started. Going to recheck them today on my lunch break.
All turn signals brake lights, wipers, radio etc are operational, the firm ride light is asap just nothing else.

May be the headlight switch... can you test output at the bulb connector to verify bulbs aren't blown (unlikely).
Do the gauges work?

I found the issue! I thought switch as well so I pulled it, checked connector and then took it apart and cleaned all the contacts etc. Then installed it and checked the red/yellow wire to make sure 12v were leaving it when switched on and they were so then I went to the mfs and checked the red/black wire for the 12v leaving to the headlights and there was nothing. So I pulled the connector and sure enough it was melted on the inside! So I bypassed it by tying the red/yellow to the red/back with a fuse in-line. Plan on replacing mfs on payday this week!
Thank you for all your help!

What are you referring to as the MFS? Multi function switch? The highbeam/turn signal stalk?
