You can also check for HVAC DTCs by following this procedure:

How to Retrieve a DTC

The heater control panel has a self-diagnosis function. To run the self-diagnosis function, do the following:
1. Turn the ignition switch ON (II).
2. Turn the fan switch OFF.
3. Press the recirculation control button to select Recirculation (recirculation indicator comes on).
4. Press and hold the recirculation control button to select Fresh (recirculation indicator goes off). Continue to hold the button until the recirculation indicator comes on for 2 seconds, and then goes off.
• If the system is OK, the recirculation indicator stays off.
• If any trouble is found, the recirculation indicator blinks the diagnostic trouble code (DTC) to indicate faulty circuit or component.

Cancelling the Self-diagnosis Function:
5. Turn the ignition switch OFF to cancel the self-diagnosis function. After completing repair work, run the selfdiagnosis
function again to make sure that there are no other malfunctions.

DTC 1 - A problem in the air mix control motor circuit.
DTC 2 - A problem in the mode control motor circuit.
DTC 3 - A problem in the evaporator temperature sensor circuit.

Also I must say, do read a bunch of old threads about A/C problems. Just asking where a part is can be the wrong approach. Start by saying just how it does not work. You can even do a search using some terms about how it does not work. It may have a leak and be low of refrigerant. It may have a cooling fan not working (or it's relay) I just know there are a lot of conditions in which the compressor is shut down.

How much did you add? If it was completely empty, vacuuming should have been done and adding oil too. This would increase the efficiency and cooling...

If the pressure gauge was accurate, that is the proper range. Problem is I've seen those all in one recharge kits and they have bad gauges underestimating the pressure...essentially not enough being added to the system hence insufficient cooling....
