I'm still having issues with my a/c as well. I followed advice, took it to an indy, and he added refrigerant. I thought all was well. It blows ice cold at first. After driving a few minutes, all the front vents just stop blowing, but my rear is still blowing cold air. If I turn it on auto they all started to blow again, but soon stopped. Again, the rear vents still blows. Any ideas?
