Hello so I recently bought a jdm double dash kit for my 03 g35. There was already a metra one installed but when I stopped my ac would turn it self off so I bought the jdm one to replace it. I took it to a audio shop and had them instal a pioneer double in and the new dash kit. But when they plugged it in the fresh air light just flashes rapidly. When we plugged the metra back in the ac controls worked fine but once we plugged the jdm one in the fresh air light on the controls would flash. So has anyone ever encountered this problem maybe shed some insight. I already took it to a dealer and they said they have no idea what's wrong with it. I'm already down 700 with radio dash and install so please help.
