Air Conditioning problem V8 Four Wheel Drive Automatic 137000 miles

I need to know where the low side of the air conditioner system is to add R134 refrigerant. I know it is the line that feels cold as the air conditioner is running. I can only see the high side (high pressure port) which is hot to the touch.

Do you
have the same problem?

The low side service valve is located on the accumulator near the fire wall. Here are some guides and diagrams to help you get the job done.
