The port on the accumulator is the low side. The high side port is smaller than the low side. The low side port is the one that gets cold when the compressor is running.

The low pressure port on the 2003 grand am is actually behind the engine, near the firewall on the passenger side. Good luck getting your hose down there though, I ended up buying an extension hose.
