Most climate controls have two temp settings - one for the passenger and one for the driver. I'm always hot and my wife's always cold so I always have mine set slightly lower than hers and the blowers on that side of the car blow that temp setting. Thus having the capability of producing a climate of two temps.
Air conditioning allows the temp of the air intake to be refridgerated slightly for warm days. But is distributed through the car at that temperature.
Normal blowers just blow on the cold setting at the temperature the air is took into the car and can only increase the temperature and not lower it.
