Completely forgot, here's the rest of the story not related to the mudder... my A/C compressor siezed up on my way up to WI. Had to drop it off at the dealer and pick it up on the way back (dealer definately charged me the stranded motorist rate). Ended up being a pretty spendy trip, although the crappy little KIA I rented finish the drive got great milage compared to the XJ.
So $800 and a new compressor later, my A/C doesn't isn't quite blowing cold, cool but not cold. I called Sam Lehman in Bloomington, IL (the dealship that did the repair), and their telling me I have a leak in the system or my h-valve needs to be replaced. I doubt I have a leak. How common is it to see an h-valve go bad?
