What to Do When the Air Conditioning Cooling Effect of Baojun 730 is Poor?

[DeChase]

Solutions for poor air conditioning cooling effect include cleaning dirty air filters and radiator condensers, and adding system refrigerant. The most common causes and solutions are as follows: 1. Low air conditioning airflow: Check if the air filter is dirty, if the blower can operate normally, and if the air conditioning flap motor can switch properly. 2. Lack of refrigerant in the air conditioning system: Inspect the system for leaks. After confirming and repairing, add refrigerant to the standard range. 3. Dirty radiator condenser: Engine cooling system failure, leading to excessively high water temperature, such as a non-working cooling fan, resulting in poor heat dissipation from the radiator and condenser.

I've been driving my Baojun 730 for almost three years now. Last summer, the air conditioning suddenly stopped cooling, leaving me sweating all over. First, I checked the cabin air filter and found it clogged with dust and leaves. I removed and cleaned it myself, which immediately improved the situation. Then, I had a friend help me check the refrigerant pressure, which was indeed low—probably due to a minor leak. After topping up the refrigerant at the repair shop, it was completely back to normal. They also reminded me to clean the condenser fins under the hood to prevent dust buildup from affecting cooling efficiency. If the compressor were faulty, it would usually make unusual noises, but mine was fine. I suggest you first check the filter and refrigerant—these simple DIY fixes can solve 80% of problems. Don’t keep driving on highways without AC or wait until winter. Regular maintenance is crucial. Also, when it's extremely hot, the AC is under more strain, so starting the car five minutes early to ventilate before turning on the AC can make it more comfortable. If none of this works, then visit a professional shop to check the electrical system or compressor—safety first.

Poor air conditioning cooling performance in the Baojun 730 is often caused by clogged filters or insufficient refrigerant. I recommend owners first check the cabin air filter location, clean or replace the filter to ensure adequate airflow. Secondly, use a pressure gauge to measure refrigerant levels - replenish promptly if below standard to avoid compressor overwork. Insufficient fan speed or severe condenser dust accumulation can also lead to poor heat dissipation affecting cooling. Don't neglect routine condenser maintenance - clean surface dust quarterly. Compressor failure may occur in older vehicles but is less common - judge by operational sounds. Electrical aging like blown fuses is another possible cause - troubleshoot with a multimeter. The easiest solution is a comprehensive inspection at a 4S shop where professional equipment can quickly locate leaks. Mandatory AC check before summer - don't substitute open windows for AC as it's both stuffy and unsafe. Long-term neglect may damage more components, ultimately costing more.

Having driven for decades, if the AC isn't cooling well, it's mostly due to a dirty filter or insufficient refrigerant. My Baojun 730 had this issue before. It's simple - go to an auto parts store to buy a new filter and try replacing it, or take it out yourself to blow off the dust. If the refrigerant is low, just add a bit, but don't overfill as it affects efficiency. If the compressor runs normally without strange noises, it's basically fine. Regularly cleaning the condenser prevents poor heat dissipation. As the car ages, there might be minor leaks in the system; timely inspection avoids worsening. Don't let small issues escalate - summer maintenance in advance saves money.
