What are the steps to diagnose the AC issue in a 2016 BMW 650i xDrive Gran Coupe?

To diagnose the AC issue in your 2016 BMW 650i xDrive Gran Coupe, start by checking for a refrigerant leak, as this is a common culprit when the air conditioning fails to blow cold air. Look for any visible signs of leaks, such as oily residue or pooling liquid beneath the vehicle, which can indicate a refrigerant leak. Next, inspect the electrical climate control system, as malfunctions here can disrupt the AC's functionality. Pay close attention to the air conditioning compressor, as issues with this component can lead to significant AC problems. If these initial checks do not reveal the issue, it may be time to consult an air conditioning specialist for a more thorough diagnosis. By following this structured approach, you can effectively troubleshoot and potentially resolve AC issues in your vehicle.
