94' 379. Last night my driver said his brake lights, wipers, backup lights, and AC fan quit. Started looking and found that one side of the fuse box is dead. I took out the fuse holder so I could flip it around and I traced the wire for that side up behind the air cleaner tubing but can't reall tell where it goes from there. Up into the dash? To the solenoid behind the frame rail? Any ideas where to look?

Should be a continuous duty accessory solenoid in the dash feeding that panel with key on. I don't recall the exact location but cycling the key on and off will likely lead you to it by sound if that part is still functional.
There are also main breakers inside the frame rail that could interrupt your cab feed.Roger McG Thanks this. -
Behind the far left little dash panel with the storage cup there is the relay that powers half the fuse box and w breaker also there is a breaker for it aswell in the fuse panel

Found a dead relay behind the far left side of the dash. I about fell over when Peterbilt charged me $80 for a chinese knock off relay, but atleast it works now. Thanks guys.

Good afternoon!
I have a similar issue I need some help with.
The right side of my fuse block is dead. I can hear/feel the solenoid clicking with the key on the far left dash panel. It is hot on both sides (tested with test light).
What am I missing?!
My tachometer, speedometer, fuel, Volt gauges are what is not working. -
If the relay is working but it's not getting down to the right side of the panel there must be a wiring issue
Check the backside of the panelRanch Hand Thanks this. -
I had a 93 pete come into the shop today. I could hear the solenoid click but still had no power to white wire that feeds the right side of the fuse box. I hit the relay with my screwdriver, all the power came back on. Don't be afraid of whacking it too hard. There were lots of fuses inside all three panels, dont forget to check those.
