On my car I followed the aluminum pressure hose (the thicker one) from the passenger side firewall until i reached the nozzle cap.
If the refill nozzle doesn't fit ask a pro.
To refill freon in an AC system, you will need to locate the service valves on the unit. Connect a refrigerant gauge to the low-pressure service valve. Slowly add freon until the pressure reaches the recommended level. Be sure to follow safety guidelines and regulations when handling freon.
To properly refill the freon in your window AC unit, you should first turn off the unit and unplug it. Then, locate the service valve on the unit and connect a refrigerant refill kit to it. Follow the instructions on the refill kit to add the appropriate amount of freon to the unit. Be careful not to overfill, as this can damage the unit. Once the freon is refilled, securely close the service valve and plug the unit back in.

Freon may need to be added when the ac is not blowing cold enough. A Freon gauge can tell you for sure if the pressure is low.
The Freon is added through the low side ac port. Using the proper type of Freon and a gauge, fill the system to the recommended pressure.
The ac is recharged through the low side ac port. Using the right type of Freon and the proper gauge for that type of Freon, connect the Freon to the port and fill to the proper gauge reading. Check the can for exact refill directions.
Use a freon gauge and freon refill can. Connect the gauge to the low pressure ac port of the 2003 Stratus. With the engine running and ac on high, fill the system until the gauge shows full.

Can anyone tell us where the lines are to refill the freon in a navigator
Personal posession of freon is illegal in the US. Unfortunately, you are required to take it to a shop.
A Freon system on a 1993 Honda Accord uses a valve on the A/C hardline where a user can connect a A/C refill can. Following directions on the refill bottle will show how much Freon is needed to pressurize the system.
