Solutions for Wuling Zhiguang's heater not being hot: 1. Check the cold/hot air control to see if the AC button is turned on and set to cold air. If so, turn it off. 2. Inspect the coolant level. If it is low, add more coolant. The car's heater generally relies on the engine's heat, which is delivered into the cabin through the cooling circulation system. The Wuling Zhiguang is a model under SAIC-GM-Wuling, with body dimensions of 3695mm in length, 1495mm in width, and 1860mm in height. The Wuling Zhiguang features a four-spoke steering wheel, popular in international passenger cars, offering better handling and a more enjoyable driving experience (standard model). Its frame is made of die-cast magnesium-aluminum alloy (commonly used in most passenger cars), which is lightweight and high-strength.
I've been in the auto repair business for many years and frequently encounter complaints about the Wuling Zhiguang's heater not working properly. The most common causes are insufficient coolant or a stuck thermostat, preventing the engine from reaching optimal temperature. In such cases, I first advise the owner to check the radiator and coolant level—it's simple enough to spot at a glance. If the coolant is low, topping it up should suffice, but avoid cheap, off-brand fluids as they can clog the pipes. Additionally, the heater control valve might be faulty, especially in older vehicles where corrosion can block the heat output. Pipe blockages are also common, particularly in northern winters due to scale buildup, requiring a flush. Overall, this issue can be fixed with minor repairs, but neglecting it can be dangerous in winter, as fogged windshields impair visibility. I recommend getting a professional inspection, usually costing a few hundred yuan—prevention is better than cure. During routine maintenance, pay extra attention to the cooling system, replace fluids regularly, and don’t wait until the heater fails to act.
As an owner of a Wuling Sunshine for five years, I just fixed the issue of the heater not blowing warm air last week. It was freezing that day, and after driving for a while, the air was still cold—I thought it was a big problem. Later, I checked the manual and decided to tackle it myself. First, I checked the coolant level and found it was low. After topping it up with pure coolant, things improved significantly. Next, I inspected the thermostat and found it wasn’t stuck, but I replaced it anyway as a precaution. The pipes were slightly clogged, so I flushed them with warm water. Honestly, Wuling vehicles are economical and practical, but their heating systems are simple and prone to minor issues. After that experience, I learned the importance of regular maintenance—now I check the radiator and fan monthly to avoid freezing. Avoid modifying the wiring casually, as a short circuit could make things worse. Fixing cars isn’t too hard, but getting help from a knowledgeable friend speeds things up. Safety comes first when driving in winter—don’t tough it out if something’s wrong.
