I had a problem with a vehicle with rear air. The dealer told me it would cost a fortune because of corrosion in the system, so I drove it on the front air for a couple years more. Then I got to thinking and realized that he was flinging bull. It turned out that the Thermal expansion valve for the rear had a kink in it that bled the fluid out of the valve. The TXV is purely gas operated, and the operation of the valve has nothing to do with the rest of the system. The fluid in the valve evapaorates at a certain temperature, opening the valve which allows cold freon to enter the cooling coils. When the coils are cold enough, the fluid in the valve shrinks and closes the valve. When the fluid in the valve leaks out, the valve thinks the system is cold, and will not allow more cold freon into the evaporator. Go see a real air conditioning mechanic who can diagnose simple problems.
