What Causes Intermittent Air Conditioning Failure in a Land Rover Range Rover?

[VanJoshua]

Reasons for intermittent air conditioning failure in a Land Rover Range Rover: 1. Excessive Refrigerant: Leads to reduced cooling efficiency. Excessive impurities in the refrigerant and refrigeration oil can cause minor blockages, resulting in insufficient cooling capacity. 2. Insufficient Refrigerant: Inadequate refrigerant leads to insufficient cooling capacity. A dirty condenser or a loose compressor drive belt can also cause the air conditioning to blow warm air. 3. Excessive Impurities: High levels of impurities in the refrigerant and refrigeration oil can cause minor blockages, leading to insufficient cooling capacity. If there are too many contaminants in the entire air conditioning system, the filter screen will inevitably become clogged, reducing the refrigerant flow capacity, increasing resistance, and decreasing the amount of refrigerant flowing to the expansion valve, thus resulting in insufficient cooling capacity.
