Why is the air conditioning in the Cadillac ATS half cool and half not cool?

[VonKhloe]

Cadillac ATS air conditioning may be half cold and half not cold due to issues with the air vents, stuck air valve plates, accidental activation of control functions, or insufficient refrigerant. Below are the detailed reasons: Air vent issues: If one of the air vent servo motors is faulty, it can cause one side of the air conditioning to not cool. Stuck air valve plates: If the air valve plates are stuck, it hinders their rotation, affecting the airflow on one side. Accidental activation of control functions: If it is an automatic air conditioning system, the dual-zone control function might have been activated. Simply deactivate the dual-zone air conditioning function. Insufficient refrigerant: There may be a leak in the air conditioning system. It is necessary to check for leaks before adding refrigerant; otherwise, this issue may recur after some time.
