Ok so I have an 2003 infiniti g35 sedan. Of course I had been experiencing the radio issue where the display goes out and the ac is on full blast and you can't control it. I decided to remove the wired to the radio and I accidently broke the white plastic part the holds the wires in place while pluged into the radio so I covered the wires and left it unplugged. Now the dash lights turn off when I turn my headlights on and the car takes a few trys before it will start. I don't think I blew a fuse that would stop the car for starting? The car lights up and it just hums. My check engine light is on now and when I took it to autozone to see what code it was giving they said it said no communication? Please help

 

maybe your grounding the wires somehow

 

You def blew some fuse, did you disconnect your battery before doing anything to the stock radio?

 

I didn't disconnect the battery before working on the radio :-( I checked all ny fuses in the 3 locations and replaced the burt out ones
