    Need more information

    Was is the compressor replaced because it electrically stopped working not a burn out

    Was is the compressor replaced because it was a burnt out with metal flake and burnt oil ?

    was there a collision front end damage condenser replaced and the compressor was replaced because there was damage from a collision ?.

    What is a loyal balance procedure performed on the new compressor ? Using the old compressor as a reference point for the quantity of oil in the system. ?

    Was the AC system filled using by weight through one of the large recovery, recycling recharge machine using the grams weight printed on the label under the hood ?

    Or was it filled with little cans and a hose to the low side service port ?.

    If small cans of refrigerant were used was at the cans that have oil inside of them and leak stop or any other item other than just 100% pure refrigerant, with nothing else mixed in it ?

    Can you hear the compressor engage in spinning?

    When it stops blowing cold, can you hear the compressor disengage stop spinning, and the suction line the large line going back to the compressor becomes warm.

    If you’re in a high humidity area when it’s been running about 15 minutes and you have it on maximum cold does the suction line hit condensation forming on the pipes water droplets ?

    Does it stop operating while you are driving down the freeway ?

    Or does it stop operating when you are stopped are in very slow moving traffic ?.

    When it is stopped and you lift the hood, do you see both fan spinning? When the air conditioning is working

    When the air conditioning stops working after 30 minutes, you lift the hood every 30 seconds or every minute do you hear the compressor attempt to try to start?

    And do you see the condenser fans momentarily try to spin and then immediately stop ?

    Was the system properly evacuated for 30 minutes prior to charging? What are system pressures (high and low side) when it blows cold, as well as when it doesn't?

    Any warning lights on the dash?

    Any two-digit codes on the MFD when you hold down the steering wheel 'a/c auto' and 'fresh/recirc' buttons while turning the car on?

    Assuming whomever replaced the parts knew what they were doing then if it were me I’d look to the blend door/vacuum system, yes. You can take it back to the repair place and have them check the pressure but I’m guessing it’s fine as it initially blows cold. I would be interested in knowing if the compressor is still turning when she goes warm? I mean is it blowing warm because the compressor has halted for some reason?
