What are the reasons for the Wuling Hongguang S's warm air not heating the feet?

[MacEli]

The reasons for the Wuling Hongguang S's warm air not heating the feet are: 1. The cable controlling the air duct outlet's baffle is damaged; 2. The pull-out wire is separated from the fixed frame. The working principle of car heating is: 1. The compressor sucks in the low-temperature and low-pressure refrigerant gas at the evaporator outlet; 2. It compresses it into high-temperature and high-pressure gas and discharges it from the compressor, reducing pressure and temperature; 3. The refrigerant gas condenses into a liquid, releasing a large amount of heat. The method to turn on the car heating is: 1. Locate the vehicle's air conditioning control button at the display position in the cockpit; 2. Click the off button on the air conditioning control button to turn on the vehicle's air conditioning; 3. Click the air conditioning button on the car's air conditioning to turn off the car's cooling function; 4. Rotate the air conditioning temperature setting knob to set the temperature to the desired level, and the warm air will be turned on.
