BMW 5 Series Air Conditioning Cooling Intermittently

[DelLily]

The reasons for the intermittent cooling of the BMW 5 Series air conditioning are as follows: Insufficient refrigerant: The car needs to frequently add refrigerant to maintain the cooling effect. If the refrigerant is insufficient, it is necessary to ask maintenance personnel to check for leaks. Decreased heat dissipation capacity of the condenser: The more oil, dirt, or debris covering the surface of the condenser, the lower its heat dissipation capacity. In addition, faults in the cooling fan or slack in the drive belt can also lead to decreased heat dissipation capacity of the condenser. Compressor failure: If the refrigerant is sufficient, check whether the air conditioning compressor can work normally or whether the air conditioning pressure switch is faulty.
