Im not sure if this is a common problem but i have a 2000 gt and the ac does not blow cold out all the vents. The 3rd middle vent to the right and the pass side blow cold. Every vent to the left gets warmer until its hot. My car has no dual temp selector so can anybody tell me how to fix it. I just charged the ac up. It could have a small leak but i need some cool air on the driver side.
