gauge lights and courtesy lamp issue

[Scott Delaney]

I jumped in my 83 C20 last night and while the headlights work fine, the gauge cluster lights and courtesy lamp under the dash (no dome light on this truck) were not working. They were working a few days ago.

My instincts tell me this is a bad headlight switch but before I contort myself up under there I figured I'd ask if anyone had any other ideas.

There is a 25A fuse on my 84 for the cabin light & a 5A fuse for the gauge lights. I would check those before removing/replacing the headlight switch.
