Mine doesn't blow very cold either, even at full blast. That was my one complaint on the vehicle in the survey.
Unless I turn both dials all the way to the blue, it's not very cold to me. Even one notch down it doesn't seem cold, and at full blue it's cold, but not icy cold.
Very unhappy with the A/C... my previous Nissan blew this one out of the water, no comparison whatsoever.
My Jeep at full blast is like my Nissan at half.
