Brother's truck, drivers door functions and brake lights dont work

[Silverwolf2691]

My brothers truck has no power to

- the radio

- the power windows

- the door locks

- and dome lights

he also has no power to his brake lights.

 

Every now and then though he gets them to turn on while driving or moving a connector. Haven't had a chance to go and see what connector he's referring to. My first thought was the IOD fuse but it gets power every now and then. All of those circuits I believe run to the in dash fuse panel. Is there anywhere else that they connect to?

Could be a faulty fuse just change it and see if it helps.

Here is a power distribution map.

Luckily it was an easy fix. Under the dash where the large bolted in connector is, there is a second smaller "normal" style connector that had come loose. that fixed everything but the brake lights. Turns out he blew the fuse under the hood. Such a simple fix for the windows that cost him an inch of water in the truck..
