Hey guys, a while back I posted about the AC freezing up. The dealer replaced the expansion valve and it seemed to have taken care of it but since then, I haven't taken any long drives. Right now, in on my way from Missouri to north Caroline and 100 miles in, my AC froze up. I had it on regular AC, not max, and had the fan set on 2. Do you think that make the grill shutters have anything to do with this? Because when they close, there's no air hitting the condenser, causing it to freeze. Let me know what you guys think.
