ECONO JUMP FROM AC AUTO

1989 Cadillac Deville

Air Conditioning problem
1989 Cadillac Deville V8 Front Wheel Drive Automatic 89000 miles

the A/C service light come on and the " Auto" setting would automatically jump to " economy mode". We took the car in and had the compressor and feon replaced. Out of the shop the A/C worked well for 1 minute and then the A/C auto setting jumped to economy and shut off the A/C. We took the car back to the shop, there is no leakage of freon, the computer has been cleared and reset, relays (black box, under the hood) checked, but we still have the same problem.. What could this problem be?
