Air Conditioner problems of the 2000 Chrysler Concorde

2000 Chrysler Concorde lh; ac evaporator failed after about 3 years; dealer charged me more than $500 for an analysis and re-charge, which lasted 2 months; took it back to dealer, who then told me it was the ac evaporator, and that it was out of warranty! to fix it would cost more than $1,200. I contacted the dealer and Chrysler on 7. 8. 2005 and was told there was nothing they could do. This is grossly unfair -- especially when Chrysler knows there is a known defect in its air conditioning systems. Chrysler said there has been no recall on this equipment so there is nothing they can do.
