Hey Scotty! Have a question about 2002 chevy cavalier 2.2l. The a/c isnt working the air compressor clutch isn't engaging but isn't locked up. P0530 code is showing on scan tool. Could this be why the Clutch isn't engaging. System was serviced not to long ago. Thanks Scotty

No. 1-1

Sounds like the pressure sensor is out or range or the refrigerant is undercharged, have you verified the refrigerant charge is ok? If so, then I'd try a new sensor.
