On the tube between the firewall and the a/c compressor. On some Fords the low pressure port is on the dryer (aluminium cylinder). Good news is the low pressure and high pressure port are different sizes. You cannot mess it up.

Remember the flow for the a/c system is :
1. From the compressor a high pressure (HP) gas goes to the condenser in front of the radiator.
2. From the condenser a HP liquid goes to an expansion device (orifice tube or expansion valve)
3. From expansion device the low pressure gas enters the firewall to the evaporator.
4. From evaporator the low pressure liquid/gas mixture goes through the dryer back to the compressor suction.

SOURCE: AC low pressure port

Go to your closest ford dealer and ask if they have a book showing all the parts and lay outs of your vehicle, or even try e-bay or a book store. But Ford should be able to help you.

What is the location of low pressure port on a 1996 eagle vision tsi?


Usually close to the drier in the tube on the low pressure side. Drier looks like an aluminum cylinder about as big around as a soda can and twice as tall with two aluminum tubes coming out of it. The port has a screw off cap to access.

Look back on the firewall for the two a/c lines. One is large and on is much smaller. The larger line is the low pressure line. Follow that line back to the compressor. The low pressure port will be on that line.

Where is the low pressure for AC located on 2000 Lincoln Navigator


The low pressure port is the only one that your AC charging tool will fit on if you are planning to charge the AC unit with refrigerant. The high side port is much larger and the quick connect tool won't fit it. Look up high toward the firewall on Fords and Lincolns.

AC Low Pressure location on 2004 Chevy Suburban


You find the AC low pressure at the top of the compressor, orientated toward you , facing the front of the vehicle. You can also follow the compressor line to reach the port.

The valve is covered a plastic cap covering it.
Near the compressor you find two ports, the high port and low port.

To find out which one is the low port, run the air conditioner for a couple of minutes withthe engine on.
Then turn off the care and touch the lines from compressor to the two ports covered with plastic caps. Only one of the pipes will be cold, the cold line will lead you to the low port.

Regards.
