Is it ice cold on the highest setting? How many bars do you put it at to get it cold under 5 mins? At first i thought the my AC was really cold but after have more people in my car and having a really hot day close to 100, I noticed it seemed lacking. Before I would put it on 1 bar and it seemed to cool the car very well I would sometimes have to switch the dial to the half way point between cold to the middle of the dial. Im hoping tint would help the car alot.
