most house are not air balanced! Air balancing is using a heat loss caluation to determine the energy required to heat or cool a room the location in each room to southern exposure a small room would need less air the larger room would need more air. the rooms located closest the the heating are cooling source will tend to get more air. you would use what we call balancing dampers to slow the flow of air to the warmer or cooler rooms? On commerial construction we hire special trades to come in and balance a system as per engineers specifications. House are small and can be done by the home owner.

There may be a stuck vent door or an issue with the heater blower control head.
I have the same problem, and looking for answers. Please help!
Your AC might be blowing out of dash vents on the windscreen as you might have turned the knob to that particular mode. It is also possible that the vent mechanism might be out of order or broken.
The heater core is leaking coolant.

If central air conditioner turns on but is not blowing through the vents, check the filter. If it is dirty, change it. Change the thermostat into cool, this will defrost the air conditioner.
Gable vents are actually counter productive when used with ridge vents. It is better to have ventilation at the soffits which will create a draft drawing in cooler air and exhausting it through the ridge.
If the air vents of the Chevy trailblazer 2004 are not blowing air, have the fuel pump checked.
you may just be low on freon
your cabin filter might be dirty
When there is a problem in the vent system it defaults to defrost setting. Check the doors & vac supply
