near the firewall on the passenger side
I found the low pressure ac port on my 2001 sable by the passenger side firewall.
No, the 1994 Mercury Sable does not use R12 for recharging the A/C unit. The 1994 Mercury Sable uses R134a Freon.

To add Freon to a 2002 Mercury Sable, first locate the low-pressure service port on the AC system, typically found on the larger diameter aluminum line. Make sure the AC is turned on to the maximum setting. Attach the refrigerant can to the low-pressure port and follow the instructions on the can to add the Freon, ensuring you do not overfill. Always wear safety equipment and check for leaks before and after adding refrigerant.
To charge the AC in a 1997 Mercury Villager, first, locate the low-pressure service port, typically found on the larger diameter AC line. Connect a refrigerant recharge kit to the port, ensuring the engine is running and the AC is set to the maximum cool setting. Add the appropriate refrigerant until the pressure gauge indicates the correct level, then disconnect the kit and replace the service port cap. Always check for leaks and ensure the system is functioning properly after charging.
The AC clutch cannot be replaced without physically removing the compressor on a 1997 Mercury Sable. The compressor and magnetic plate must be removed before you can access the clutch.
*Assuming* you are looking for the connection for adding coolant: facing the engine, the refill port is in the back left hand corner, up near the firewall. It has a black screw-on cap on it.
On a 2004 Mercury Sable, the low-pressure port for the air conditioning system is typically located on the larger diameter aluminum line that connects the compressor to the evaporator. It is usually found near the front of the engine compartment, close to the firewall. Look for a service port with a plastic cap, often labeled with an "L" or blue color. Always ensure the engine is off and the system is properly handled when working with AC components.

If the AC is on, this is normal.

the lower port is located under the hood, at the very top of the engine compartment on the passenger side. Its a black hose with a black cap. see attached link for video i found on you tube. http://www.youtube.com/watch?v=cBOTUXCannkn youtube
