So I've had my 350z for about a month, and for the first 3 weeks the air conditioning worked fine, it would blow hot and cold air whenever needed, and it did whatever I told it to. But starting last week it literally started doing whatever it wants. It'll start blowing hot air full blast out of nowhere, then later it'll blow cold air at half blast. The cold air still works when it occasionally decides to blow it, so it's something with the computer I'm assuming. Sometimes the AC light will be blinking rapidly, then sometimes it'll be on, but either way it doesn't do what I tell it to. Is there an easy way to fix this or do I need to take it to a professional?

 

Do you have an aftermarket stereo?

 

No, everything is stock, although I did open up my whole front console recently, and a sirius xm radio box or whatever it is was kind of like stuffed in there with all the wires under the radio, looks like a really ghetto setup, should I take that out? I've seen some people say that if the ribbon cable is pinched then it could affect it.

 

Well I figured out what was wrong with it. I took the the ribbon cable out of the white ac box, and when I put it back in, I didn't push it all the way back in and my ac is completely responsive now.
