Anybody know where the heck the fuse for back of sleeper lights are? I have took my test light to every stinking fuse in the truck even under bed and don’t have a bad one.

Might be under the gauge panel

If the fuse(s) are good, you may want to check the wires @ the hinge area of the mattress box. The routing, at least on mine, is horrible that area, and they pinch under the frame.

It being paccar, try disconnect all batteries for 30 min and let the cab controller reset. They are notorious for software quirks with lights, dash gauges, etc.

may not be the problem, just mentioning it as a reminder to those who may searching for solutions for this kind of stuff.

If it's a sleeper truck the fuse for the load lights is in the sleeper fuse box

I’ll try to reset cab control first since it’s the easiest.

Along with the CECU in the cab if it has a sleeper, it has chassis nodes that probably control this. I've been chasing a bad one in mine for quite some time..... Don't get me started.

I still haven’t got mine fixed. I’m about to lite a match
