dash board is showing "very low refrigerant level, a/c compressor off" we tried adding refrigerant but because compressor is off it won't let me. Is there a way to reset the compressor? This is a 1997 Deville Concours

Enter the onboard diagnostics and clear the DTC's. That will enable the compressor.

Do what Ranger said. Then while u are adding refrigerant, the compressor will come on/off a lot. It won't stay on totally until the refrigerant is full. I thought my car was broke because the A/C wouldn't stay on at first until I figured it out.

Disconnecting the battery will clear the DTC's, but will add some "U" codes.
