I finally found it myself under an electrical connection, on top of the dryer.
Under the dash on the passenger side
I believe it is under the air filter housing.
You can find the air conditioning low pressure charging port on top of the air conditioning compressor. The low pressure port will be on the right hand side of the air conditioning compressor.
the service port is on top the rec-drier on the right side fire wall, its hard to find,
The Low side line attaches to the compressor on the driver side of compressor. The charging port faced forward. The high pressure port faces up.
The low-side port is located next to the compressor. It will have a cap on it. This is very visible..and will be where you charge your system. Your charging adaptor will only fit the low-side anyway. follow the directions to your charging kit carefully.
The low side charging port is located high up, near the firewall, on the driver's side, right by the brake master cylinder.
I had the same problem. It is on the right side of the firewall under the heater box. CT
there is a high side charging port up top and a low side underneath the car on the compressor.
It is near the firewall on the passenger side of the vehicle. It has a blue cap.
On the passenger side near the fire wall. Coming out of the fire wall you will first see the high side port then the expansion value the next port is the low side port. You will know for sure because the charging hose will only fit on the low side port. You can also see a diagram of this on the link below. Just follow the icon "Find your cars low side port."
The best thing to do is is to start at the left side of the vehicle where the drier is and follow the large line from that point until you find the charging port. If you can't find the port like that, chances are someone removed the A/C.
