Good morning to see if any expert can help me, it's been a couple of days since my air conditioning comes out cold, after diagnosing with xentry, there are no recorded failures, and the actuators are ok, I only see something lowers the pressure of the refrigerant gas about 5 bars, it may be due to lack of gas, some other idea, Thank you in advance.

Double check the compressor governor PWM valve. It jams and prevents pumping normal cooling pressure, just as if charge was low from leaking.Originally Posted by Marcosvg

With 5Bar (cold engine bay) A/C should cool nearly well.
It does not so :
Read the "compressor solenoid"...
** IF ** solenoid % duty is shown active without high side pressure increase then replace your failed/jammed $50 solenoid or new compressor.
