How to Repair the Non-Heating Issue of Wuling Zhiguang's Warm Air?
3 Answers
Methods to address the non-heating issue of Wuling Zhiguang's warm air: 1. Locate the car key below the steering wheel, turn the key to start the engine; 2. After the vehicle starts, turn the right knob of the air conditioning system clockwise to activate the system; 3. Once the air conditioning is on, press the AC button on the right knob of the air conditioning system to turn off the AC cooling function, which will then allow the warm air to heat up. The vehicle's warm air system can heat the air inside the cabin or the air drawn from outside, increasing the interior temperature. In terms of body dimensions, the vehicle measures 3797mm in length, 1510mm in width, 1820mm in height, with a wheelbase of 2500mm.
Last winter, the heater in my Wuling Zhiguang wasn't warming up, making the car extremely cold. I first checked the coolant and found the level in the reservoir was low, so I added some antifreeze. But it still didn't work—when the engine warmed up, the heater hoses felt ice cold. Later, I thought the thermostat might be stuck, preventing the engine from reaching proper temperature. I took it apart myself to check and replaced it with a new thermostat, which immediately solved the problem. Through this process, I also learned some DIY skills—bleeding air bubbles is crucial, as trapped air in the system can prevent the heater from working. Finally, a reminder: heater issues are quite common in older cars. Don't delay fixing them, as fogged-up windows can be dangerous, especially in rainy or foggy conditions—safety comes first when driving. Paying attention during regular maintenance can save a lot of trouble.
As someone who frequently works on car repairs, when the heater isn't producing enough warmth, I start with the cooling system. First, check if the coolant level is sufficient and top it up if needed. Second, start the car and wait for the engine to reach normal operating temperature, then check if the radiator fan is spinning; if not, the fan might be faulty. Third, try bleeding the system by placing a bottle at the heater outlet to remove air bubbles. If the issue persists, the heater core might be clogged or leaking, requiring a professional flush. Basic tools like a wrench and an empty bottle are enough for simple DIY fixes at home. However, don't push your luck—if the problem seems complex, visit a 4S shop. Parts for the Wuling Sunshine are affordable; replacing the thermostat costs just a few dozen yuan. DIY repairs can be fun, but be cautious to avoid burns. Regular coolant maintenance is key to reducing the risk of clogs.
