I bought recently infiniti ex35 2010, now I affronted a problem with the AC system, it starts automatically on mode auto at the same time that I start the engine, and i want to ask if this problem has related to ambient temperature sensor, because the ambient temperature is not showed in my dashboard?
Thanks for listening.

Not sure I understand the problem, but you should be able to see the ambient temperature when you select it using the button on the dash. Also if you turn off the ac auto, or off button, it should not turn on when you start the engine.

Maybe your button is sticking. Spray a little WD40 or electrical cleaner or both. (Very little.)
