I took mine to the dealer today to have them check it out, and as my luck goes, after a half hour and $50, they told me it is working fine. I was skeptical, but paid the $50 and left. Sure enough the A/C was cold and working fine. (I hadn't even used on the way to the dealer.) I drove around town, made a few stops and each time I got back in the air was cold. Half way home, (I live about 8 miles out of town) no more cold air. So there goes my $50, and I don't know more than I did. So I'm not sure where I go from here.....
