There are 2 fuses boxes in cab and 1 in engine bay
we test the fuses, we dont change them out willy nilly.
even better, is to measure the voltage at at the radio.
the power pin is 12vdc, keyon
if not the fuse is blown or the wire is cut.
end story.
my guess is car wiring was hacked long ago with stereo upgrades
or other hacks, (alarms,etc)
old cars are like that, hacked.
