The air conditioner compressor on my '92 is always engaged (and putting out cold air) even when the controls are set to 'off'. I assume the problem is in the control unit, but guess it could be mechanical with the compressor clutch stuck in the engaged position. The compressor was replaced in the last 2 years and doesn't have many hours on it. I assume mine is not the first NSX to have had this problem! Any help diagnosing and repairing? Thanks.
