I have a similar issue (2000 LX w 186k miles). Dealer wanted to replace the a/c suction line and recharge for $370. I said no thanks. Worst case, I'll have them do it in the spring, but meantime I'll look into doing it myself. If anyone has replaced this line before, I'd appreciate any advice or cautionary comments they have to offer. I figure I should have to worry about any evacuation, considering the thing blows nothing resembling cold air at this time.
