1996 Pontiac Grand AM: Low A/c Service valve?

Low A/c pressure port.These is the port from where A/c refrigerant has to be charged.

The low side service port is located near the back of the A/C compressor.
For its easy access follow the larger line away from the compressor and it is about 4 inches down the pipe.
You have to reach down between the high pressure hose and the intake to feel it. It had a blue cap on it from the factory.

See below the  picture of the a new A/C hose is marked with a blue arrow where the port is.
