Problem overview

Some Cadillac ATS owners report experiencing issues such as the center console overheating and the rear AC blowing hot air while the front AC remains cold. These problems may stem from a refrigerant leak or a faulty AC compressor, which can cause the rear AC to blow hot air. Additionally, the center console overheating could be linked to a bad electrical connector, broken wire, or a defect in the climate control unit affecting the blower motor. Insufficient refrigerant in the AC system is another factor that may contribute to the rear AC's poor performance. Furthermore, owners should check the blend door actuator, as it plays a crucial role in directing air across the heater core or AC evaporator. To resolve these issues, it is advisable to consult a qualified mechanic or HVAC technician familiar with car air conditioning systems for accurate diagnosis and repair.
