Would this help to save fuel?
One of the simple ways I myself to observe if the AC is cycled is thru the cooling fans. My mazda AC blows really ice cold - I could feel that the AC kicks on and off thru the fans. I feel good on that.
My SVXi blow ice cold too (but not as good as the Mazda when on traffic jams). Once the AC is on, the both cooling fans are always, always running; they might go to different speed but I never seen them off, most of the times. I don't know...I actually don't like it, feel consuming alot of gas (feeling) and keep wearing out my cooling fans (shorten the lifespan)
I guess they are just the different system. But I was very positive, there're couple times in the cool mornings, my AC was cycled off a few times ... I heard the fans were off when it was on AC mode not Econ. Weird.
But I actually felt happy on that....felt like it worked as my Mazda and Nissan On and off = enough charge = save more battery energy...
