I just changed the radio out in my 05, and last night noticed that I do not have any interior or dash lights. Al fuses look good, headlights, tail lights, blinkers, hazards are all working fine.

Thinking back, the problem may have originated before the radio, because a while back I was moving my truck (I haven't driven it much lately) and noticed that I had no lights in the center section where my climate control is. I can't remember if I had dash lights then or not, but I know I had interior lights.

I was using the interior lights while installing the radio. I didn't mess with any of the factory wiring, simply wiring the radio to a harness that plugs into the factory harness. I've tried unplugging the radio harness to see if the lights came back, but no go.

I'm kind of stumped as to what it could be. The only thing that changed since having interior lights and not having them, is running my cable for satellite radio under the dash, but I'm fairly certain I did not disturb any wiring, but it is possible I guess, so if there is something under the dash that could cause this that I could check, I'd gladly jump on it.

Anyone have any ideas? I did pull the IOD or whatever fuse that is in the fuse holder for gauge cluster, it was good. All gauges work. I'm not sure about speedo since I haven't driven it but everything else is good to go.

 

Well I feel like a genius. I checked all fuses with a multimeter checking for continuity and apparently I was cold and ran through them fast because on another check I found my fuse labeled illum was blown. So the one fuse I really should have double checked, I either skipped or went across so fast that the multi meter was still beeping from the previous fuse and I heard the beep and went on. Everything seems to be fine back to normal now, including me being an idiot.

 

Haha, don't feel bad. I missed a blown fuse too the other day. It's still a nice find.
