Air Conditioner Temp

What's the proper temperature coming out of a fully operational air conditioner? The air out of the vents in my Dodge is only 60-70 degrees so it has to run full blast nearly all the time to cool. The Dealer says the system is fully charged.

Your temp coming out of your vents should be somewhere between 10 - 20 degrees below the ambient temp.

60 degrees is already cool enough.

Thanks
