I’m currently having similar issues on my 2006 Chevrolet Silverado.
My doors won’t power unlock or lock , windows won’t go up and down, radio doesn’t turn on, my four gauges are not working( battery, oil, pressure, temperature, gas) and interior lighting only turns on when I manually pushed the buttons.
My battery light is on so I replaced the battery because it had gone out but didn’t fix the problem.
My ABS light is on.
No check engine light.
I checked my fuses and relays and they all look good.
not sure the problem.
