Passat ordered how to turn on the warm air.

When the water temperature rises, it is recommended to adjust the temperature to the red area and turn on the fan. Warm air is generally suitable for blowing feet, and blowing face is easy to get sleepy. The driving device of the heater is powered by a DC motor, which can send hot air into the car through a blower and also remove frost from the windshield of the cab. The heating mode of Passat Mausoleum is as follows: 1. For automatic air conditioning models, just turn up the air conditioning temperature and then turn on the fan above; Manual air conditioner models need to turn the hot and cold air switch to the red area and turn on the fan. 2. If the vehicle has a warm air valve, you can touch the warm air valve behind the two warm air pipes by hand. If the temperatures are in the same open state, one is hot and the other is cold. 3. There are two black rubber hoses with the same thickness behind the engine heating pipe, which can be judged by hand feeling. The knob of the workbench needs to be set to the red area, and the heating and cooling selection knob needs to be turned to the red bottom of the indicator light to warn the warm air, and the blue one is the cold air. The heat source of the heater is sent to the radiator of the heater through the water pipe with the help of the residual heat of the engine cooling water. As long as the engine is not turned off, the cooling water will keep a "small circulation" with the radiator.
