Should the AC Be Turned On in a Car During Rainy Days?
2 Answers
It is not always necessary to turn on the AC to defog the windows on rainy days, as in most cases, turning on the cold or warm air in the car can help eliminate fog. More details about the car AC switch are as follows: Definition of the AC Switch: Simply put, the car AC switch is the air conditioning cooling switch. AC stands for "Air-conditioning," meaning air conditioning device. This button controls the activation and deactivation of the compressor, and the car air conditioning's cooling function relies on the operation of the compressor. How the AC Works: After turning on the car air conditioning's fan, air will blow out because the blower in the air conditioning system starts working. However, the cooling system of the air conditioning is not yet activated because the compressor has not started working. Once the AC switch is turned on, the car's onboard computer receives the signal from the AC switch and then sends a signal to the air conditioning compressor. Upon receiving the command, the compressor starts working, and only then does the car air conditioning begin to cool.
Turning on the AC on rainy days is absolutely necessary! Having driven all kinds of vehicles in the rain, experience tells me that without AC, the windows fog up easily. Once moisture builds up, visibility gets blurry, and that's just unsafe. The AC quickly removes humidity, helping defog the windows so you can see clearly and drive steadily. Sure, running the AC consumes a bit more fuel, but what’s that compared to the risk of an accident? In rainy seasons, the car interior can also get musty—turning on the AC keeps the air dry and passengers comfortable. Make it a habit to turn it on as soon as it rains—prevention is key, so you don’t have to slam on the brakes when fog suddenly appears.
