So I have an 04' G35 coupe and I have the Hvac issue were my a/c blows on 60 degrees non stop and my radio doesn't work I have read on here about checking the a/c sensor or un doing to ribbon cable that connects from the cd player to the circuit board. I have also checked to see if maybe a transistor is loose and needs to be soldered non of this fixes have been of any use does anyone else happen to how to fix it with out buying a double din after market unit (money is tight and winter will be upon us soon) don't want to freeze my *** off lol but any advice would be helpful.

 

Try replacing the stereo head unit minus the Bose stereo.
