320 CDI wagon - aircondition issue.
I just need a little help, gent's.
The aircondition is completely crazy - left side no cooling, only outside air.
Right side, nice chilled air.
The center console down between the front seats and to back seat very hot air.
Where should I start troubleshooting?

poor AC cooling
Then you review every Temp sensors and pressure data using scanner.
"Low refrigerant".… that means leak!
In AC system leaks are not easy and nor cheap to repair well the first time.
Do you know how to use a UV die or gas detector to help locate discharge location ???

Where you should start is by scanning the HVAC AAC Module for a fresh list of faults.

Pls come again!
Your AC shop can't locate your leak... then find it yourself!
Simply look for oily stains near your AC circuit loop.
