I replaced the radio, hooked up the new one blew a fuse. I replaced the fuse blew that one, unhooked the radio replaced the fuse the dash lights worked. Put in a 20 amp fuse instead of a 10amp (dumb) now the lights don't work but the radio does, i cant read my gauges none of the dimmer lights work, replaced the dimmer switch still don't work. i cant figure it out, must tear dash apart to find problem i guess, maybe i burned a wire with the 20amp
