I owned a Nissan Maxima that exhibited this same behavior.

My wife owns a Lexus and the heater start blowing hot air from the vents as soon as I turn the climate control up.

I don't know what the climate is like where you live, but here temperatures can get as low as -35 Celsius (about -30 F) sometimes, and I kind of like the fact that it waits to get warm before it sends air through the vents... Believe me, the only thing that sucks more than -35 degree temperature is having it blown in your face by a fan on a cold engine! Windchill is harsh!

Yup, all Nissans/Infinitis are like this. The fan will not start blowing until the engine reaches operating temperature. The only exception is if you put it on defrost.
