I ended up finding the port so I figured I'd answer my own question and maybe save someone else some pain down the road. I was initially looking at the high pressure port, which is located right behind the air filter. The port looks like it would fit the recharge hose, but it is just slightly to big. I was told that all low pressure ports are the same size, so after I figured that out it was pretty obvious I had the wrong port instead of needing some sort of reducer or something. The low pressure port is behind the engine by the transmission oil dip stick. Basically right below the middle of the windshield. You can see the AC line come up and go back down and it's right on that hump in the line. Mine has a black cap on it. It's pretty easy to get to.
I have a 2003 Grand Prix GT and the AC recharge port is right behind the motor on the firewall. Look for the silver pipes coming out of the firewall right near the middle. You will see the recharge port on one of the pipes there.
The 2002 Pontiac Grand Prix OBD 2 port is under driver side dash right of steering column
On my '93, there is no consumer serviceable port. I think the recharge has to be done by a technician.
You can add Freon to your 2005 Pontiac Grand Prix air conditioning system through the low pressure port. The low pressure port can be found on the air conditioner compressor.
below the steering wheel
Center/ top of the Firewall.
The 1996 Pontiac Grand Prix OBD 2 port is on lower edge of dash; right of steering column
I own a 96'' grand prix 2 door myself and had to find it myself it's located under the air filter box right underneath there are to lines with 2 black caps one is for cold and ones for hot to recharge it's the smaller line port with the smaller nozle. You can recharge it yourself just go to walmart to the automotive section and look for a tall can with a hose and gauge connected to it the directions are on the back of the can hope I helped a little.
The port is located on the firewall, top/center.
To recharge the AC on the 2002 Ford Escort ZX2 you need to use the low pressure fill port. It is located on the larger of the two hoses coming off the compressor.
where is the ac recharge port on a 93 ford explorer located?
On the low side service port that is located on the a/c compressor manifold.....
