I have a 1998 Deville, the warning message says " low coolant, A/C off. I cannot add freon with the compressor off. Does anyone know how to fix this?? Thanks for your help.

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

Simultaneously press and hold the OFF & WARMER buttons til the DIC lights up. After the DTC's are displayed, answer the prompt with the HI & LOW fan buttons. HI = yes, LOW = no. eg. PCM? = yes. I forget the next prompts but they will be answered no til you see CLEAR PCM CODES = yes
