Question about 1997 Cadillac Seville
I had the same problem. The thing is you need to have the air on while you're recharging it and the compressor won't turn on. I was able to recharge the air by disconnecting the positive battery cable and reconnecting to reset the computer and immediately have someone inside the vehicle turn the air on before the computer can recognize that the refrigerant is too low and disable the compressor again. This will allow for the compressor to turn on and for you to recharge the air. Make sure that you have the replacement refrigerant connected before you turn the ac on so the refrigerant goes in and keeps the compressor on before the computer catches it again.

I had to take mine in to get recharged and they had to reprogram the compressor to come on.

Tips for a great answer:
Have the air-conditioning system discharged or evacuated of refrigerant by certified personnel at a dealer service department or automotive air-conditioning repair facility.
Raise the hood and disconnect the negative battery cable terminal from the battery using a box-end wrench.
Disconnect the electrical plug-in connector from the compressor clutch by hand.
Remove the drive serpentine belt from the compressor clutch pulley by taking the tension from the pulley using a breaker bar and compressing the torsion spring tensioner.
Disconnect the refrigerant lines from the compressor with the box-end wrenches. Plug the open fittings to prevent the accidental entry of dirt and moisture; quarter-inch rubber stoppers are a good fit for these connections.
Loosen the mounting bolts with the box-end wrenches, and remove the bolts from the compressor clutch mounting bracket and lift the clutch out of the vehicle.
Pour out the refrigerant oil into a graduated container so you know how much new oil to add to the new compressor.
Installation is in the reverse order of removal. Always replace all O-rings with new ones that are specifically made for use with the new R-134a refrigerant. Lubricate the new O-rings with R-134a-compatible refrigerant oil.
Evacuate and recharge the system with the proper amount of R-134a refrigerant by the same certified mechanic that discharged the unit before you replaced clutch. Have the mechanic start the engine and let it run for a few minutes; this will let the system stabilize and the compressor cycle on and off.
