So, I went to charge my r12 today. After many attempts and not getting it to put itself into Econ mode, I finally got it to start taking r12. The clutch kicked on and off fast, and all was good. All of a sudden the clutch stopped moving and I started to smoke because the pully wasn't turning free of the clutch, the clutch stopped. Now I am back to the car putting it into econ mode. So, what are the chances that it is just a bad clutch and that the compressor is still good?? Thanks for the help.
