What is the reason for no air coming out of the Wuling Hongguang air conditioner?

First, check whether the temperature of the inlet and outlet pipes of the heater core is hot to the touch. If both pipes are hot, inspect the air ducts or the hot/cold air control flaps. If the inlet pipe is hot but the outlet pipe is not, it may indicate a blockage in the heater core, which requires replacement. If neither pipe is hot, the coolant circulation system should be examined. It is recommended to visit a repair shop to diagnose and confirm the faulty component. The correct method for using the car heater: 1. Do not turn on the heater immediately after starting the vehicle. In daily driving, many drivers habitually turn on the heater as soon as they get in the car. However, this practice is incorrect because, in winter, the engine's coolant temperature is very low when first started. Turning on the air conditioner at this time will not quickly raise the cabin temperature but will instead slow down the warming of the coolant.
After driving the Wuling Hongguang for so long, the most common issue with the AC not blowing air is a faulty fan motor, which could be due to seized bearings or overheating damage—simply replacing it will fix the problem. Another frequent cause is a blown fuse, usually located in the engine compartment fuse box; check the AC blower fuse. Poor connector contact is also common, often caused by dust buildup leading to loose connections and no power. Commercial vehicles like the Wuling Hongguang are used intensively, making the fan more prone to issues—it's advisable to repair it early to avoid delays in cargo transport. Wiring shorts aren’t uncommon either, especially in humid environments where corrosion is more likely. If you’re unsure, it’s best to visit a professional shop for a comprehensive fix.
