It is on or near the receiver dryer or shinny can looking thing at the right rear of the engine compartment. You really need gauges and a refrigerant recovery system to properly do the job.

The low side port is on the low pressure hose off the AC compressor. Easy to get to from under car.

The 1998 Plymouth Grand Voyager low pressure port can be found on the top of the air conditioner compressor. The low pressure port should be labeled as such.

You can put Freon into your 1997 Nissan Pathfinder from the low pressure port. Connect the Freon bottle to the port. Release the Freon into the air conditioning system.
