Dash and side switch lighting inop

My gauge and switch lighting is not working. Headlights, park lights, and turn signals all function properly. Iíve turned the rheostat the full range and the courtesy light comes on fine. I get no gauge lighting.

Iím brand new to motorhomes so any ideas appreciated! 2000 HR Ambassador.

First look for blown fuse. Next is to try HL switch. They are often older than coach popular GM or Ford car parts. My coach has separate dimmer wheel I missed it and ordered a bunch of dash bulbs lol.

In my front drivers side electrical bay I have large fuse box and two smaller ones.

In the #1 smaller box there is a 10 amp fuse labeled Key SW Feed, this is the fuse that controls the lights on the dash.

I had a problem with my pull out head light switch that also dims these lights, it has a rheostat type of dimmer and it was bad, had to replace this to get my lights to work as the power goes through it.
