2007 DB9 AIRCON PROBLEM-TURN OFF

[Carnival40]

In cold weather AC works without a problem. The warmer the more turned off.
It turn off in spite of the switch of air conditioning is still lit.
Blower work perfectly all the time-when the aircon is off the air begins to fly more and warmer air (just stop cold).
Then you need to turn off the air conditioning or the engine for a few minutes and turn on the air conditioning or the engine again it generally works fine, but for a few minutes.
When is hotter the more it shut down and the longer it takes to re-enable it or is it definitely related to the temperature or pressure.
Sometimes when I turn off after a while turns on alone.
I did a test and plugged air conditioning to instrumentation. On the basis of instrument readings have found that at the time how you turned off, the pressure in the system clearly indicating that the system is turned off.(AC swith was ON)
I replaced the two elements of the aircon
4G43-19F598-AA Sensors A / C Evap
1R12-89-10192 A / C SWITCH-HIGH PRES
Nothing is nieda³o.
Did someone have the same probelm? Can anyone know how to solve this problem?

Sounds as if it's low on refrigerant gas.

To the garage you must go. It will end up cheaper than changing parts willy nilly!
