What is the BMW air conditioning auto function?
1 Answers
BMW air conditioning auto is the automatic mode of the air conditioning. When pressed, the air conditioning will operate in automatic mode, automatically adjusting the airflow and the compressor's engagement based on the set temperature and the actual ambient temperature. If the car makes a vibrating sound as soon as the air conditioning is turned on, it may be due to the following reasons: 1. Dirty air filter: A dirty air filter can cause excessive noise and abnormal sounds. 2. Debris in the blower fan blades: Debris in the blower fan blades can cause abnormal sounds. You can test this by turning on the blower without starting the engine to see if the sound appears. If it does, the issue is likely with the blower. 3. Fan issues: Deformed fan blades or a damaged fan motor in the car's air conditioning system. 4. Worn clutch bearing: A worn clutch bearing in the air conditioning pump can cause the engine sound to become louder when the air conditioning is turned on. This component cannot be replaced individually; the entire air conditioning pump assembly must be replaced.
