I put in a new radio last week. I've done this quite a few times before and even went by the instructions, but this time the radio doesn't turn on nor do my cab lights, under hood light, or door buzzers. And I checked my fuses and blew the radio fuse so I replaced it and still no change. Any help?

 

look for the IOD fuse in the end of the dash.
also check the fuses in the power distribution box beside the battery.
