Where is the port to charge my air conditioner

The charging port is located in the larger of the two hoses/lines that come from the AC compressor, the fill port will accept only the right fitting from the charging source hose fitting. Before you add refrigerant you need to locate the leak, the refrigerant doesn't just disappear, it leaks out somewhere.. My guess would be the AC compressor front seal.

What you are wanting to add is R134a Freon. The port that you are talking about looks like the same connection that is on your tires. It is called a Schrader valve. They have a cap on them like a tire valve stem. They are located on the air conditioner lines that lead to and from the compressor to the cabin. They are different sizes and if you are not familiar with them, find someone that is because you can get hurt or damage your a/c if you make a mistake.

The port in the larger of the 2 AC lines from the compressor is the port you charge at.

The easiest way to locate the low side charge port on any vehicle is to locate the A/C compressor, follow the "larger" of the two lines all the way back to the firewall. Some where along that line you will find the low side charge port.
Good luck.

look in the center of the firewall behind the engine for a black cap that looks like a tire valve stem cap ,......only larger

LOOK AT LOWER BACK OF ENGINE LOWER FIREWALL LOOK FOR EVAPORATOR LINE WITH BLUE CAP THATS YOUR CHARGE PORT.YOU NEED A LONG CHARGE LINE TO REACH THE CHARGE PORT.

They hide these service ports good,don`t they?Follow the large ac line coming from the ac compressor,until you come to the low side service port,this is the easiest way.

Low Side service port is on a larger hose assembly on passenger side heading out of the compressor to the firewall into the vehicle compartment(evap housing).This is the service port which will be low pressure and will accept freon.High side is always small metal piping and heads up front towards the reciever drier and condenser....be safe

remember you will always charge an air conditioner on the low side. which is always on the larger hose. there is a smaller one which is the high side so stay away from the small one.. look up near the radiator and see if you see the dryer which is about 3 inches across and 8 inches long and looks like a cylinder.. on this device there is a port where you can charge it .. also this year might be up near the firewall .. they change locations too often .. thanks and holler if you need more.

follow the air conditioner line from the front of the car. valve on the line will be near the front
