THIS IS DEPENDENT ON AMBIENT AIR TEMPERATURE , THAT IS TEMP OUTSIDE NEED TO GET TEMPERATURE PRESSURE CHART TO DETERMINE THIS NUMBER , ALSO LOW SIDE OR HIGH SIDE , LOW SIDE PRESSURE IS THE ONE I USUALLY USE TO ADJUST CHARGE , BUT AS I SAID IT IS DIRECTLY RELATED TO AMBIENT AIR SO THERE IS NOT A GIVEN NUMBER SHOULD BE ABLE TO GET CHART @ AUTO SUPPLIER OR JUST ASK ONE OF YOUR AC PEOPLE IF THEY CAN MAKE YOU A COPY OF ONE .

There are 2 hoses that come off of condensor in front of radiator. 1 is high side, has large cap on top goes to a/c compressor. The other is low side it, it goes toward firewall into or on the receiver dryer (looks like big can) You will find the charge fitting there. It is a smaller fitting usually blue or black cap on it.

Rick, u will need to take your car to get serviced. If your ac is not working properly it might be something inside that needs to be looked at. You might need to replace your heater box.

The AC charge port is the on low pressure AC line (large line from compressor) near the firewall. Take care not to overcharge, there are other causes of no cooling like a stuck AC compressor cycling switch or a air temp control blend door motor malfunction, what is the issue u have? does the AC compressor run?

If you find the big round silver thing (reciever/dryer) it is in it or in the same line nearby. Probably area of passenger side close to firewall. The low pressure side is the larger of the tubes.
