Upon start up of car there is no radio display. It's blank as no power. Radio does not work. AC controls do not work. But defroster is on. Only button working on is the 4 way flashers/emergency flashers. I've checked all fuses. No issues. Took AC control panel off and checked connections, all were good even pulled radio display with bezel for AC vents to check connection again all is good. Just stopped working to today. Tried pulling fuses for radio and AC to start car with and without fuses cycled car. But nothing is working.
