Mercedes-Benz Sprinter 3500 AC blows cold for 20 minutes then stops on Mercedes-Benz Sprinter 3500

Some Mercedes-Benz Sprinter 3500 owners report experiencing issues with their AC system, such as it blowing cold air for only 20 minutes before stopping. This problem may be attributed to a refrigerant leak, which can go unnoticed until the AC ceases to cool. Others have encountered electrical climate control issues or compressor malfunctions that lead to hot air blowing after a brief period of cooling. Additionally, some owners find that the AC works intermittently, particularly in cooler temperatures, but fails to perform adequately in warmer conditions. Airflow problems, such as weak air output, may also arise due to clogged cabin filters or vent issues. Furthermore, external factors like extreme ambient temperatures can negatively affect AC performance. It is recommended that affected owners consult a qualified technician for a thorough inspection and resolution of the issue.
