Question
QUESTION: 2001 Deville a/c will not turn on. Compressor will not spin. Fooling around shutting car off and a/c heat off then back on made the compressor turn on for a few seconds. All fuses are good. There has been no recent work to car to expect error. Heater works and all other functions work properly. A/c was working properly blowing cold air without any noises from compressor.

ANSWER: It is most likely that you either have a leak in the AC system or depending upon where you live, It is to cold for the AC to engage.
