Where does the cold air come from in a car?
While your car’s AC is responsible for creating the cold air that you need to cool it off, it’s the blower motor in your car that is responsible for actually delivering the cold air to you through your vent. This blower is designed to take the cold air from your AC system and push it out through all the different vents in your car.

Where does the coldest air come from on an AC unit?
The rooms closest to the unit will receive the strongest and coldest air flow, while those farthest away will unfortunately get the weakest air flow. One way to balance out the air flow to all the rooms in your house is to close the vents in the cooler rooms partway.
Why does my Mitsubishi Triton not have air conditioning?
Doh! The final straw was the 38.5 degree day yesterday – having to work outside in the sun for most of the day, it was damn annoying to get into the car and have air conditioning that was next to useless. I was pretty sure the problem was lack of heat rejection from the condenser coil.
