My air conditioner compressor clutch is engaging when it is not switched on. At idle, it clicks on for a bit, then off. even when it is disengaged, it turns very slowly. Do the clutches fail engaged or disengaged? As an interim fix, is it safe to pull the connector on top of the compressor? And what is the root cause of the problem? I have not done much investigating as of yet. [Its been a long week] Also, after I shut down the engine, is sounded like pressure escaping until it bled dry after about a minute. I await your counsel.
