Why does the Haval H6's air conditioning not cool when parked?

[LeGage]

Haval H6's air conditioning not cooling when parked can be due to the following specific reasons: Lack of refrigerant: Car air conditioning systems generally require refrigerant (Freon) replenishment every 2-3 years, with some vehicles needing it annually. Even with excellent sealing, refrigerant can still dissipate over time, especially if there are minor leaks in the air conditioning pipes or condenser. Dirty condenser: During summer, when poor air conditioning performance is often noticed, testing might show no issues with the system and normal high/low pressure readings. In such cases, repair shops or 4S stores often recommend cleaning the radiator. The primary purpose of cleaning the radiator and condenser is to improve heat dissipation.

I once encountered an issue with the air conditioning not cooling when parked while driving my Haval H6, and it was really unbearable. When the car is parked, the engine speed is lower, and if the air conditioning compressor doesn't start or the fan doesn't spin, the cooling effect is significantly worse. The most common issue is insufficient refrigerant or a leak, where aging pipes or damaged gaskets can cause leaks. Compressor failure is also quite common; if the bearings wear out, it can't drive the cooling cycle. Another issue is a clogged condenser with dust, which leads to poor heat dissipation and no cooling. When I took it to the repair shop that time, the technician added refrigerant, and it worked fine afterward. I recommend checking if the air conditioning fan is functioning properly before parking. If there's no cool air from the vents, get it checked or visit a professional repair shop immediately—don't wait until it becomes a safety issue. During regular maintenance, clean the condenser to prevent clogging, which can save a lot of trouble.

As a friend who frequently works on car repairs, I've noticed that the non-cooling issue with the Haval H6's parking air conditioning is often related to the electrical system. It could be due to a burnt-out compressor relay, where corroded contacts lead to poor electrical connection, preventing the compressor from operating. Alternatively, a blown fuse might be the culprit, where excessive current causes the circuit to break. When parked, low battery voltage can also be a factor—if the air conditioning control module sensor is faulty, it won't respond to commands. A loose fan motor can also cause cooling problems. I've helped someone address this before: first, check the air conditioning fuse in the fuse box; if it's intact, then inspect the relay and wiring connections. Avoid dismantling the compressor yourself to prevent damaging electronic components. Make it a habit to inspect the air conditioning circuit connections every six months to prevent issues before they arise, which is also beneficial for the car's overall health.

I drive a Haval H6 to commute, and it's really frustrating when the air conditioning doesn't cool in summer when parked. A common reason is insufficient refrigerant, which naturally evaporates or leaks over time. If the vents only blow hot air without cooling, the compressor might not be engaging or the fan could be clogged with dirt. This is more noticeable in hot weather and affects comfort. My solution is simple: after starting the car, press the AUTO button and wait a few seconds to see if it cools. If not, try manually adjusting the temperature or fan speed. If it still doesn’t work, it’s likely time to refill the refrigerant. For routine maintenance, get an AC recharge every two years to prevent leaks. When parking, try to find a shady spot to reduce the load on the AC.
