What are the reasons for the lack of heating in Wuling Zhiguang?

There are two main reasons for the lack of heating in Wuling Zhiguang: 1. Engine cooling system issues. Check the temperature of the two inlet pipes of the heater core. If both pipes are hot, it indicates a problem with the air flow control mechanism. Conversely, if both pipes are cold, or if one is hot and the other is cold, it suggests an issue with the cooling system. 2. Malfunction of the heating control mechanism. The car's heating system uses a blower to direct heat from the heater core into the cabin. If the air flow is insufficient or the distribution of hot and cold air is poor, preventing the heat from the heater core from being effectively dispersed, the heating temperature will not rise. In this case, first check if the air filter is dirty or clogged, and clean or replace it if necessary. Then inspect the operation of the blower at each speed setting to ensure that each setting achieves sufficient rotation speed.
I've encountered this issue several times, and friends who drive Wuling Zhiguang often complain about the discomfort of having no warm air in winter. Having driven for over a decade, I know the most common reason is insufficient coolant—such as a leaking radiator or the expansion valve not working when temperatures are too low, preventing hot air from coming out. Another major issue is a clogged heater core, possibly due to rust buildup, which requires cleaning or replacement. There's also the problem of the fan not spinning, resulting in reduced airflow or no air at all. Faulty control switches are not uncommon, especially in older vehicles. Lastly, don’t overlook a clogged air filter, as restricted airflow naturally prevents warm air from blowing out. In short, the lack of warm air not only affects comfort but may also compromise driving safety. I recommend first checking the coolant level and temperature gauge to ensure they’re adequate before investigating other components. If the issue persists, visit a reliable repair shop instead of toughing it out.
