What Causes Normal Low Pressure but Low High Pressure in Car Air Conditioning?

[VonMariana]

When a car's air conditioning system exhibits low low-side pressure and normal high-side pressure, it is typically caused by a malfunction or failure of the air conditioning compressor. Below is a detailed explanation of this issue: 1. For compressor failure leading to normal low pressure but low high pressure, the solution generally involves replacing the air conditioning compressor with a new one. 2. Due to the cramped and compact space around the car's air conditioning compressor, disassembly is quite inconvenient. Additionally, temporary recovery of the refrigerant is required, making the process labor-intensive. It is recommended to have this service performed at a 4S dealership.
