Why does the warm air sometimes blow cold and sometimes hot?
1 Answers
Warm air sometimes blows cold and sometimes hot because the warm water valve in some vehicles is controlled by the air conditioning computer. During operation, internal sticking or influence from the air conditioning computer can cause the warm water valve to close or fail to open. As a result, hot water sometimes cannot enter the warm water radiator in time, leading to intermittent warm air from the air conditioning. Car air conditioning refers to the air conditioning device installed in vehicles, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. The air conditioning system has become one of the indicators to measure whether a car is fully equipped with functions.
