What are the reasons for the BEV BJAC air conditioning compressor not working?

[NicoleMarie]

Below are the reasons why the BEV BJAC air conditioning compressor is not working: 1. Internal wear: The compressor has severe internal wear, making it unable to function properly. Since the compressor plays a crucial role in the air conditioning system—its main job is to compress and deliver cold air—it operates at high speeds for extended periods, which is one of the reasons it may fail to work normally. 2. Circuit system failure: A circuit system malfunction can effectively prevent the car's air conditioning compressor from operating properly. If this issue arises, the owner can check whether the circuit is functioning smoothly and inspect the temperature sensor solenoid valve.

Recently, I encountered a situation with my BAIC New Energy vehicle where the air conditioning wasn't cooling and the compressor wasn't working. There could be several possible reasons. For example, a fuse might have blown—this can be checked in the car's fuse box, and replacing it should fix the issue. Another possibility is loose or short-circuited wiring, where a connector isn't plugged in tightly or is worn out, preventing current flow. The compressor itself might be faulty, with coil issues or seized bearings causing it to jam and produce strange noises when starting. If the refrigerant is low, the protection system may prevent the compressor from starting to avoid damage. Problems in the high-voltage system of the new energy vehicle could also cause the entire air conditioning system to fail, such as a software error in the control module requiring a reset. I recommend starting with checking the fuse, and if that doesn't work, take it directly to a 4S shop for repair—driving without air conditioning in summer is unbearable. Regular inspections can help prevent such issues in advance.

From a car repair perspective, there are several common reasons for air conditioning compressor failure. A blown fuse is the most basic issue and should be checked and replaced immediately. For relay failure, use a multimeter to test whether the power supply is normal. Short circuits or open circuits in the wiring can interrupt signals, requiring a full vehicle inspection of the wiring harness. Mechanical failure of the compressor, such as internal wear preventing startup, can be judged by listening to the sound. Low refrigerant pressure may cause the system to automatically disable startup. For new energy vehicles, issues with high-voltage components like the fuse module might be the main cause. Malfunctioning controller buttons should also be considered. It's recommended to diagnose step by step and avoid disassembling randomly. High-voltage components are dangerous and must be handled by professionals. Using the right tools can save time and effort.

Simply put, the main reasons why the compressor doesn't work when I drive are: The fuse is blown—replace it with a new one in the fuse box. The control switch is broken—the AC panel doesn't respond when pressed. There's a wiring issue—poor connection or worn-out wires preventing electricity from passing. The compressor itself is faulty—it doesn't start or makes noise. Refrigerant leakage leads to insufficient pressure. New energy high-voltage system failure might be related. Don't try to fix complex issues yourself—go to a professional shop for solutions.
