Interior lights not working

[eli weldon]

So recently I’ve noticed none of the interior lights in my 96 C1500 stopped working altogether (dome light, lights in the footwell, glovebox light). I highly doubt all the bulbs went out at once, and I have replaced them all with LEDs within the past year. I checked the fuses and they seem to be fine. The dome override switch didn’t work either. And ideas on what’s wrong?

Do they come on if you roll the dimmer wheel on the headlight switch all the way up to the top position? If so, my guess is bad plunger switches on one or more doors. If not, my guess is a bad headlight switch.

I’ve tried that, and it doesn’t work. There is power going to the switch because when I have my headlights on I can still dim the gauge cluster lights.

Power going in doesn't necessarily mean power going out. If I were you I'd swap headlight switches and see where that gets you.

I tried getting a new headlight switch, that didn’t work either lol. I may try replacing the plunger switches but I wouldn’t think that they both crap out at the same time. If that doesn’t work my guess would maybe be something wrong with the wiring.

Replaced the plunger switch, did not fix problem

Update: I’m an idiot. I looked at the wrong fuse. Thought it would be the lights fuse but it was the one labeled CTSY, for courtesy lights.

Do you remember the part number for your courtesy led bulbs? I have a 92. They were taken out b4 I got it
