Mercedes-Benz S63 AMG AC blower not functioning after replacing blower and resistor, persists with no air from vents on Mercedes-Benz S63 AMG

Some Mercedes-Benz S63 AMG owners report experiencing issues with the AC blower not functioning even after replacing the blower and resistor, resulting in no air coming from the vents. These problems may stem from a refrigerant leak, which can cause the AC system to malfunction and prevent cool air from circulating. Additionally, electrical climate control issues, such as faulty fuses, relays, or wiring, can hinder the blower's performance. A malfunctioning air conditioning compressor may also contribute to the lack of airflow from the vents. Owners are advised to check for refrigerant leaks, inspect the electrical components related to the blower motor, and verify the condition of the air conditioning compressor. If these troubleshooting steps do not resolve the issue, consulting a professional mechanic or an authorized Mercedes-Benz service center is recommended for a thorough diagnosis and repair.
