Bus lights
Looking for help fixing light issues with my 2003 chevy express 3500. It was made into a prison bus before I bought it last year. I renovated it into a mobile home for travelling. Currently the high mount brake lights in the rear are not working, I replaced the bulbs and the fuse under the drivers seat. The reverse lights in the rear are also not working and replaced bulbs and fuse as well. One of three high mount front light is out, bulbs and fuse were also replaced. I did have the license plate light out but after changing bulb and fused that one worked. I need all these lights to work to pass a NYS inspection. Any tips?
under drivers seat fuses 13,4,16,6,14,19,20,21,22 and
under hood 28,3,4,9,10,42,43,44,45, fuses reading 0v but pass the beep test
wires from ignition red pink and orange all at 12v
