What are the reasons for the Wuling Hongguang compressor not working?

Long-term operation under high-speed load conditions may cause mechanical wear and tear of compressor components in advance, leading to failure. The method to detect compressor issues mainly involves comparing the pressure values on the high-pressure gauge and low-pressure gauge with normal values to determine the specific reason for the compressor not working. Additional information: Introduction to Wuling Hongguang S air conditioning faults is as follows: 1. Air conditioning temperature regulation system: Check if the heater switch control cable is detached and whether the heater water valve is in the closed position. You can touch the front and back of the water valve by hand; under normal circumstances, the side near the engine should be hotter, while the side near the vehicle body should be cooler. Otherwise, adjust the heater switch to the closed position. 2. Avoid prolonged high-speed operation of the engine: Check if the condenser is blocked by dirt. If there is no blockage, observe the refrigerant sight glass to see if there is excessive refrigerant, indicated by visible liquid flow.
From what I see, your issue is likely due to a faulty Wuling Hongguang compressor, which is quite common. My own car had this problem before. Common causes include the compressor clutch not engaging properly or a loose/slipping belt, preventing the AC from starting. Voltage instability or a blown fuse can also cut off the entire circuit. If it's a sensor issue, like a failed temperature sensor, the compressor won't respond. Lack of refrigerant or a clogged AC system can also cause it to stop working. I suggest popping the hood—listen for the compressor startup sound. If there's no sound, check the fuse box; if there's sound but no airflow, inspect the refrigerant. Get it fixed promptly, or you'll suffer in summer heat with an uncomfortable ride. A friend’s car had a seized compressor that fried the whole system, costing way more for a full replacement. Pay attention to AC usage habits—don’t blast it at max right after starting the car. Gradual care saves hassle in the long run.
I think the compressor not working might be related to the electrical system. I've repaired similar cars before, and usually, you need to check for loose or corroded wiring connections, because over time, moisture can get in and affect conductivity. It could also be that the solenoid valve is broken and can't control the compressor's on/off, causing the fan to spin but the AC not to cool. Fan issues can also indirectly affect the compressor, leading to excessive energy consumption and burnout. If the control unit is faulty, the AC switch signal won't get through. It's best to plug in a diagnostic scanner to check for fault codes—it'll be clear at a glance. Also, check the refrigerant pressure; if it's too high or too low, the compressor will shut down protectively. I remember last time I was repairing a car, I cleaned the entire AC filter and found that blockage could cause extra strain on the compressor. Safety first—if it's raining and the windshield fogs up without cold air, it can be really dangerous not being able to see the road clearly.
