Actually, it sounds like there is a problem with the blend air door. This door is near the heater core. Its job is to turn one direction to allow the fan to blow air through the heater core and heat the vehicle, and the other direction is for the AC to cool the vehicle. Based on your description, it sounds like it is stuck in the middle. Therefore, you don't get good AC or heat and there is less air entering the vehicle.
