1997 Cadillac Seville AC low, AC compresser off

The check engine light and the A/C low are seperate issues. If I remember correctly, and your climate panel has a passenger side temp that adjusts with a rocker type switch, I can get you into diagnostics to obtain the trouble codes. If you press and hold OFF, and the passenger temp switch in the warmer position, it will eventually light all the displays, and you can release the buttons. At that point it should start displaying trouble codes by module on the info center. I am not sure, but they should be alphabetical by module. You are looking specifically for ABS, ACM, and PCM codes(or ECM). Record the codes, and report them back.
