1997 Cadillac Seville Strange A/C Problem with 97 Seville!

Has anything been done to address this yet, have the pressures been read? You need to know that you have a proper charge amount, a properly installed expansion device(orifice tube), and a compressor capable of pumping. Sometimes the orifice tube is in backwards, sometimes it is clogged. Pressure readings can provide some insight. Look for possibly a slipping compressor, too weak electromagnetic clutch and/or excessive air gap between the drive plate and the pulley.
