Hello I will help you with your question, During high humidity you can have vapor or even frost blowing out the vents. The path the driver's air takes through the ac evaporator core means it is just a bit cooler so you might see some vapor. This is normal on occasion. Low refrigerant in the system can make the core colder than intended and might be enough to freeze it. As long as the system is cooling sufficiently there is no issue with a little vapor. Please let me know how I can help you with your question Thank you
