AC not blowing cold air

Please find a little more info , is the A/C SYSTEM functioning , mechanically AND electrically , but the air from the vents is not as cold as it used to be? When you have it at the mechanics next time , note down a few items and post them HERE for additional help. AFTER car has been shut off for at LEAST 10 minutes , see what the pressures are on high side , and low side. Next , with it runnign , turn it on 'MAX-COOL' then let it idle and write down those pressures low side when clutch is NOT engaged , then when it is , write down the LOWEST reading it goes to before it disengages. same for the high side , during clutch engagement then what it goes up to when it goes off. NEXT , visually inspect the temperature controls for proper function 'blend door'air mix control actuator Heater control valve function if equipped. Next and importantly , while all this was going on , was the radiator/condenser fan ALWAYS cycling along with the compressor clutch?

Hi, when you say " I have replaced " Does this mean you have paid a shop or done it in you own yard.? Regards Matt
