There is generally a test port on the injection rail.Make sure you use only a high pressure tester and proper test fittings.The pressure is quite high and can be a serious fire hazard if not done right.

Freon is added to the lower pressure line port. It is the only port a refill kit will fit. I suggest taking it to a shop that does A/C repair if you do not know that already.

To add R-134a refrigerant to a 2000 Mercury Villager, first ensure the engine is off and locate the low-pressure service port, typically found on the larger diameter AC line. Remove the cap from the port, then connect an R-134a charging hose fitted with a gauge. Start the engine and turn the AC to the maximum setting; then, slowly add refrigerant while monitoring the pressure gauge to avoid overcharging. Once the desired pressure is achieved, disconnect the hose and replace the service port cap.
The AC port for recharging the air conditioning system on a 2001 Mercury Villager is typically located on the passenger side of the engine bay. Look for the low-pressure service port, which is usually situated on the larger diameter line connected to the AC compressor. It will have a plastic cap, often colored blue or black. Make sure to consult your vehicle's manual for specific details and safety instructions.
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.
Error codes on a 1997 Mercury Villager can be found by connecting an OBDII code reader to the diagnostic port. The service manual has a full list of error codes and their causes.
