I just bought a used 2007 infiniti g35 4 door, I try to turn on the AC and it does not get cold at all. What could be the cause of this ?

What is your question?

I've only had the car for a day. It blows heat when I need the heater but the AC doesn't come out cold.

What makes this problem better or worse?

How long has your 2007 INFINITI G35 had this problem?
