Hello guys

My AC system is empty and I am thinking about filling it with R12 replacement. I have noticed that the clutch of the compressor does not work aswell. Is there some sort of a protection built in that if the system is empty the clutch does not engage?

Thanks guys.

There's a pressure switch wired in the factory AC system that will prevent the compressor clutch from energizing if there isn't enough refrigerant in the system. It's there to protect the compressor from running dry in the event that much of the refrigerant (and the oil that goes with it) leaks out.

 

Thanks buddy! I did not qute understand the writeup in the workshop manual. thank you for the clarification.
