the r-134a service ports on todays cars are industry standard sizes. the high side port is slightly larger than the low side so you can not hook them up in reverse.make sure your not trying to hook up to the high side port. low side ports are usually located on or near the drier. or in the larger diameter a/c line going to evaporator.

It is on or near the reciever dryer or shiny looking thing at the right rear of the engine compartment. You need gauges to correctly add refigerant as you can overcharge it.

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.
