Question about 1995 Cadillac DeVille
I looked in the car manual & it clearly reads that if in econ mode, the A/C Compressor will be shut off. Looked up on computer that all codes must be reset& new codes entered when replacing A/C Compressor, also said could be switches on dash for choices.
There should be a switch inside the car to choose whether you want econ mode on or off, Econ mode helps to save fuel and power.

You'll need to have the A/C system serviced. It is low on freon so the compressor isn't coming on, and you won't have any A/C. Usually you'll just need some freon.

This usually means the ac refridgerant is low. In Econ mode the ac compressor will not turn on, your car is staying in Econ to avoid damage to the compressor. If you are low on refrigerant it means you have a leak. Don't just buy a can and refil, have a professional shop check for leaks and fill the system with the proper oil and add refrigerant to the proper pressure.

If the car was retro fitted with R134a this was a common problem. There was a low side pressure sensor that needs to be changed. R134a runs different pressures than the r12.. When you go down the road the condenser cools off the system and the pressure drops below the minimum pressure. You need to make sure that the system is fully charged, not just cold to the feel. Both pipes coming out of the firewall need to be the same temp. this makes sure that the evaporator is flooded.
I hope this helped. Re-post if you need more info. Have a nice day and good luck.
