What are the reasons for the Baojun 730 air conditioner not cooling?
2 Answers
Baojun 730 air conditioner not cooling reasons: 1. Lack of refrigerant, car air conditioners need to be refilled with refrigerant every 2 to 3 years, refrigerant loss is mainly due to leakage, if the car air conditioner does not cool and starts cooling again after adding refrigerant, then it is necessary to consider whether there is a lack of refrigerant; 2. Damaged air conditioner flap, damage to the air conditioner flap motor is a relatively common fault, if there is a problem with the flap motor, even if the air conditioner can cool, cold air can only come out through the gaps; 3. Dirty condenser, the main purpose of cleaning the radiator and condenser is for cooling, they need to be cleaned regularly, first use an air gun to blow clean, then wash with a water gun; 4. Aged or loose belt, during maintenance, 4S shops will remind to replace the belt, if slippage occurs during use, it can cause the belt to break, leading to the air conditioner not cooling and other situations.
I own a Baojun 730, and it's really frustrating when the air conditioning stops cooling. The first time it happened was during summer driving—the car kept getting hotter, and I initially thought the switch was broken. Turned out, after checking at my friend's shop, it was due to a refrigerant leak, probably caused by a crack in the pipe. Replacing the part fixed it. But there are other causes too, like an aging compressor that stops working—that’s the most expensive repair. Or the evaporator coil freezing up, where the fan doesn’t blow cold air out. Electrical issues, like a faulty temperature sensor, can also give false readings. Regular maintenance, like changing the cabin air filter, can prevent such problems—otherwise, if it’s clogged, no air will come out at all. My advice is to first check if there’s any cold air blowing out. If there’s no air, it might be a duct issue; if there’s air but it’s not cold, then the cooling system needs inspection. Either way, don’t delay—driving in high heat can make you drowsy and dangerous.
