I was wondering about the expansion valve, but I would have thought you wouldn't be able to get a full charge with a bad valve. I to need information from someone technical, but I think they are replacing the valve today.
I didn't even know about this forum or Fastlane until after I got to where I am now. I wish I had known this looks like a great place.
AutoZone charged me $342 for the compressor and $49 for Rec/dryer.
