What's the reason for the low air volume of the Wuling Hongguang S heater?

The low air volume of the heater may be due to the low speed of the blower or a blocked pipeline. More information about the car heater is as follows: 1. The heater should not blow directly at the head, as prolonged exposure can cause driver fatigue and affect driving safety. It is recommended to open the window slightly to allow air circulation when using the heater for a long time, ensuring sufficient oxygen levels in the car and keeping the driver alert. 2. Owners should not leave the heater on while sleeping in the car, as this can easily lead to carbon monoxide poisoning. 3. After turning on the heater, the car becomes a closed space, creating an ideal environment for bacterial growth and spread. If someone smokes in the car, the amines and nicotine in the smoke will adhere to the surface of the evaporator. When the air conditioning is not used frequently or during rainy weather, bacteria can proliferate on the evaporator surface, leading to air pollution inside the car when the air conditioning is turned on again.
My car often has the issue of weak warm air flow, mostly due to a severely clogged air filter where dust and leaves accumulate and block the airflow. I usually open the filter box under the glove compartment, take out the filter, and find it completely black. Cleaning it with a hair dryer or water usually solves the problem. If the airflow remains weak after cleaning, it might be due to an aging blower motor slowing down or ventilation ducts blocked by debris. Try increasing the temperature to see if there's any change—sometimes a faulty control switch can prevent the airflow from increasing. For the Wuling Hongguang, the filter is located in front of the passenger seat. If you're handy, you can do it yourself—it saves trouble and prevents bigger issues. Remember to check the filter every season; replacing it is cheap and easy, so don’t wait until winter when you're freezing to deal with it.
