Look at your ac compresser, there will be two different size hoses on it. the large line is the high pressure , the small hose is the low. If your trying to ad freon, your hose from the can will only fit the small line fitting, it wont allow you to access to high pressure side. The fittings will usually have a small black cover on them, just unscrew it and your fill hose will connect to it. You can only fill from the low side, the fill hose wont fit the high side fitting

I am assuming you are talking about the A/C. From the compressor, locate the large black hose comming from the A/C compressor. It goes into a small hard line, the valve on this hard line is the low side service port. The hose the comes from the A/C condencer is the high side service port.
