Hmmm, after reading these posts I think I'm ok.
I noticed the same AC prob, and took the X into the dealership today. The culprit, that leaky high pressure line.
They told me $250 for replacement and full recharge. I figured they got me by the nutz cause I don't have the foggiest idea how to mess with A/C stuff. But if folks are doing it by hand for $200, it sounds like I didn't get a bad deal...
I haven't gone to pick the X up, but hopefully that takes care of that.
