You need a manifold gauge set. You set up a fan in front of your vehicle. You hook up the manifold gauge set. You run the motor with the AC on max until the compressor clutch starts cycling, and you note the high and low pressures on both the high and low side. There should be a chart which comes with the manifold gauge set which gives you ambient air temperature and relative humidity, and what the corresponding pressures should be under those conditions.

How do you identify the low pressure port valve on the ac 02 f350?
it will be on the accumalater or the small one
Ac clutch f350 does not engage?
Check the following items......... 1. Freon levels. 2. Electrical harnesses for the a/c system. 3. Clutch air gap. 4. Pressure switches.....
Why ac does not want to work on your 1998 jeep Cherokee sport?
Have a shop check the AC system pressure
Refrigerant capacity of 1990 fORD F350 ac?
2.15 lbs
Why doesn't cold air come out when ac on a 2003 Toyota Camry?
Check if the blower motor is working, and you will need to check the pressure in the AC line.
Why would the AC compressor turn on and off repeatedly on a 99 Olds Aurora resulting in no cooling little on pass side System is pressurized but when compressor turns off pressure rises to 65?
The ac system may be low on Freon. Check the pressure with a gauge. If the pressure is ok then check the ac relay, as they can be intermittent.
Low pressure ac port 2000 buick century?
The low pressure AC port on a 2000 Buick Century is located on the accumulator. It is used to fill the system with refrigerant and to check pressure levels.
What would cause AC low pressure line to be to high?
If you check the pressure on the low pressure line and it is very high then you should make sure the compressor is ON. You may have put the blower on, but on the dashboard there usually is a button that turns on the ac compressor. When the comp is on the pressure will drop into the "blue" range. This is the first check, and the simplest
What would cause the AC compressor of a 2005 Toyota Tacoma not to turn on besides a fuse?
Check the Freon pressure first. The AC compressor will not turn on if the Freon pressure is too low.
Cabin ac filter on 2000 f350?
Does not have a serviceable filter like some cars.
Why does your car shake when you turn off the AC?
Check the alternator or the main lead of the ac wire to check for either if there is too much pressure is being applicated to the alternator or if theirs a shortage in the main lead wire to the ac
How do you charge the ac in a 2001 Buick le Sabre?
Freon is added through the low side ac port. A gauge is recommended to check the Freon pressure, as too low or too high pressure can cause the ac not to work properly.
