Does anyone have any suggestions on what I can do about my AC. The temperature warms up from 72 to 78-80 at stop lights and stop and go traffic. While I am going the temp of the air hitting the driver is 72 and inside the vent is 58. It doesn't sound light at big difference (72-78) but it is the difference between sweating and not while coming home from work. I had thought about changing crank pulley size to a larger one, but I didn't know if it would mess things up and I didn't know where to get one nor did I know what size to actually get. I also thought putting an electrical fan blowing into the core (by the grille). Are there any other suggestions? yes do one of these or no, don't do those?
