Multiple reasons may cause this issue: 1. The compressor itself is faulty and cannot start. 2. There is a problem with the power supply to the compressor. 3. The compressor lacks refrigerant and cannot start. 4. The vehicle's air conditioning control panel is damaged. Any of these issues can lead to the compressor not working. For more details, please see below: Additional information: For the air conditioning system of a motor vehicle to function, the compressor must be operational. The prerequisite for the compressor to work is that the motor vehicle must be started. Once the vehicle is started, the power transmission system will provide part of the power to the compressor to make it work. For small-displacement vehicles, after the compressor starts working, there will be a noticeable decrease in vehicle power. At this time, whether overtaking or accelerating, it is necessary to downshift to avoid insufficient power.

I just encountered a situation where the Wuling Hongguang's air conditioning compressor wasn't working, what a headache! It happened during a long summer trip, the car was as hot as a steamer, and not a bit of cold air came out of the vents. I thought about it myself, it might be an electrical issue, like a blown AC fuse—you can find it in the engine compartment fuse box; or a loose plug causing unstable signals. If the belt is loose or broken, the compressor won't start either. At the repair shop, the mechanic said it could also be insufficient refrigerant, a system leak triggering the protection mechanism to lock the compressor. It's recommended to first check the fuse and plug yourself, if that doesn't work, quickly find a professional. Delaying it, driving in high temperatures can easily lead to fatigue and accidents, not worth the risk.

From daily maintenance experience, there are many reasons why the air conditioning compressor may not work. Issues with the compressor drive system, such as relay failure or circuit disconnection, can result in no sound from the compressor clutch during inspection. Mechanical problems like belt slippage or breakage require observing the engine's operating condition. If the refrigerant pressure is too low, the compressor will self-lock for protection, indicating a system leak. Control unit errors or poor switch contact are also common issues. When troubleshooting, first check the fuse box—usually located in the engine compartment—by pulling out the fuses to see if they are blown. Then test the relay and wiring connections. If these are fine, pressure testing or software diagnostics may be needed. Avoid forcing the AC to start to prevent damaging more components; immediate repair is safer.

Driving a Wuling Hongguang for deliveries, suddenly the AC stops cooling, really frustrating. The compressor isn't working, I'll quickly check myself: open the engine bay to inspect the belt—if it's broken, it needs replacing; then look at the fuse box under the steering wheel, find the AC fuse and try replacing it. If the plug is loose, re-secure it, sometimes that's the issue. Or the pressure switch might be faulty, but that requires professional testing. If these quick fixes don't work, drive to the repair shop. This issue needs prompt attention—driving in summer without AC can make it hard to focus, which is dangerous.

Don't underestimate the non-operating air conditioning compressor in a Wuling Hongguang. It's a safety hazard, especially during scorching summers when high cabin temperatures may lead to heatstroke and impair driving judgment. Common failures include poor electrical contacts or refrigerant leaks—the latter triggering protection devices to prevent compressor activation. If the belt is damaged or lacks lubrication, mechanical components may seize. Long-term neglect could potentially cause engine damage. Upon noticing AC failure, immediately pull over to inspect fuses and connections. Avoid pushing through during peak traffic congestion; instead, seek a technician's assistance promptly to ensure road safety.
