i have a 1995 ls 400 and my stereo doesn’t work at all doesn’t turn on the screen is either completely dead or there is a blown fuze somewhere I found the engine fuze box and the interior one but I can’t figure out why there’s no power going to it anyone have any answers why that is ?

 

Well, you have the diagram for the fuse block. Pull the radio fuses and physically look at them, you'll be able to tell if they're broken. They're transparent to allow you to see the piece of metal.

 

There are other fuses which supply +B 12V to the radio. You need to check the fuse radio No.1 and the dome fuse. Those are located in the big fuse/relay box behind the car battery. Check those too but what I worry about is that the radio itself is dead.
