Open the hood and look to your left and right below the coolant reserve tank you should see a silver steel line going across the engine at the very front of the hood right by the hood latch and you will see on the left side right on this line a black cap and that is your "recharge port" for the R134A AC. hope this helps! I got a 2001 SE and that is where mine is.... :-)

On my '93, there is no consumer serviceable port. I think the recharge has to be done by a technician.
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 AC recharge port on a 2004 GMC envoy is on the low pressure connection. It is the larger of two hoses near the firewall.
You can recharge your 2004 Lincoln LS from the low pressure port. The low pressure port can be found on the top of the air conditioning compressor.

lay on your back and look up at the compressor in the right front section of the engine compartment, it is a fitting on the larger hose coming off of the compressor.
I have a 2001, and the recharge port is on the passenger side, on the firewall. It's got a green cap on it and so far has been impossible to get to. Good luck.
